Six months,

David:You might be surprised
what we find.
People have to recognize
this is a sales job every time you go in
to get your car fixed. David:You can’t afford
to miss your

drivers know about when
to get an oil change.David:Can I ask you a really
quick question for
CBC? Sure. David: Your oil
change sticker up there. Yes. David: How often do
you get the oil done? Whenever it tells me. Whatever that kilometres
on there, that’s when I take it in. David: And do you know how
often that is, every–? About every six months. David: How often do
you change your oil? Once every three months. Every 5,000 kilometres. Why? ‘Cause that’s what
they recommend to do. David: Who does?

costing as much as a hundred

the right advice?
Can you read something for me? Sure. David: What’s that
line there say? Change the

engine oil every year. Yeah. David: How often

you can go longer before
replacing your oil.[ ♪♪ ] Siri From Phone:The

David:We want to
see what dealerships,
which are owned independently
from the manufacturer,
will recommend to us.So we choose six vehicles with
the same instructions in their
owner’s manual.That is, replace the oil when
the indicator light comes on.
Not to exceed 12 months

whichever comes first.[ ♪♪ ] David:Then we pay
a visit to one of each
corresponding dealerships.David:The service advisor at

same recommendation

David:But at
this Fiat facility.
David:How about
this Dodge dealership?
David:And at
this Ford dealer.
David:Remember, the manual
says as long as the indicator
doesn’t come on,
it can go twice that.
David:So who’s telling
the truth and who’s taking
us for a ride?Mark Wynnton is a licensed
mechanic and former instructor
in south-western Ontario.Oil changes, what if the
dealership says get it done every six months but your
owner’s manual there says only every year. The people who built the car
and engineered it and assembled it, all their
knowledge is in that book, and that is king. It overrides anything
a dealer can tell you. In most cases today, cars have
an oil change monitoring system where the car alerts the driver
to the oil change requirement when that might be. That’s what you follow. Nothing else. Otherwise, you’re changing
your oil too soon, you’re polluting
the environment, you’re wasting your money. [ ♪♪ ] David:So far,three of the five
dealerships we visit do not
even mention following that
oil change monitoring system.
So we head out for
one last test drive
with our 6th vehicle,this 2013 Jeep Wrangler.It belongs to Eric.He works for us.[ ♪♪ ] David:Just like our other
five test vehicles,
Eric’s owner’s manual says to
change the oil when that change
oil message appears.But no later than 12
months or 16,000 kilometres,
whichever comes first.It’s been eight months and
about a thousand kilometres
since the oil’s been changed.And there’s no
oil change message.
So what will they recommend
we do at this Jeep dealership?
I was looking at the owner’s
manual and it was saying that you can go up to 12
months or like 16,000 so —But why is it —
like why would —
David:A marketing ploy?Time to call in science.Fluid Life in
Brantford, Ontario.
It’s one of the largest
providers of oil analysis in
North America.Manager Mark Sherman
first pumps out
a sample to be tested.He also takes a
sample of brand-new,
unused oil.Mark:A little basis
of comparison.
David:Certainly looks darker
but does it need to be changed?
I’m using sample
stickers, Mark. David:The samples are
then shaken, weighed,
and placed in this
ICP spectrometer.
Mark:What we’re doing here
is we’re taking the sample,
inserting it into
the instrument
and it burns it
at temperatures
that are actually hotter
than the sun.
We’re really looking at whether
or not the oil looks like it is in a typical state for your
engine or whether it looks like it’s in an unacceptable state. David:The results should
tell us whether the oil in the
Jeep is still good.Give me the upshot. What have you found? Overall, these engine
oil results look really good actually. There was a slight
amount of oil degradation, but contamination level was
nice and the wear metals were quite low. David: Do you have a sense
of how much longer it could stay in that vehicle before it
needs to be changed? Well, it’s always difficult
to say that with a definitive answer but I can probably tell
you that this engine oil is good for probably another 3,000,
4,000 kilometres. David: Is there any
need to change it right now? I would not change
this oil right now. No, it looks good. David:So why might some
dealerships push more frequent
oil changes than needed?Lucas Leung,
he’s got a possible answer.
He’s a former service
advisor who’s worked
at six different dealerships.Because they’re
coming in more often, every time they walk in,
it’s an opportunity for us to find things on the
vehicle that may be wrong. David: So if you can upsell
the customer to have them doing an oil change more often than
maybe they need to do it, that’s your opportunity
to sell them other stuff. Correct. So every time they come more
often, it is a possibility that I can recommend more. David:We contact the
four dealerships whose service
advisors told us to change
the oil more often than the
indicator says.Dodge and Fiat say they stand
by the advice given by their
service advisors.Jeep’s got nothing to add.But the Ford
dealership confirms
drivers should consult theirowner’s manual to determine
their oil change interval.
So let’s take a look at this.Back at the gas station, we ask
people to take a look at their
owner’s manual.What’s that say there? However your engine oil and
filter must be changed at least once a year. It says every year, yeah. David: Yeah, it means maybe
you’re doing the oil four times more often than
you’re supposed to. Now I will go back to
Honda and tell them that. David: So, you’re going right
to the dealership? Absolutely. David: Why would a dealership
want you to come in to get something done more often? For the money. [ ♪♪ ] There’s 50 million cars in
Canada and they all take four, five litres so that’s a lot of
hazardous waste and it’s a waste of money. I mean, people have to
recognize this is a sales job. Every time you go in
to get your car fixed, there is no two ways about that.And I don’t know how to put
that any clearer than that.

About the Author: Michael Flood


  1. Oil should be changed at least 5000 miles because if you keep running the same oil say a year or so and if you have a regular oil in it and not synthetic you will have oil sludge buildup that’s basically like having cholesterol buildup in your arteries it’ll start blocking oil passages in the engine that more engine where in tear I’ve seen it first hand. Here in the us we have oil recycling centers that take old oil and make it in to new oil.

  2. I use full synthetic in my cars and a quality filter, I change every 5,000 miles. The timeline is not as important since I believe synthetic has a longer engine shelf life.

  3. I have repaired or replaced hundreds of engines that had A critical part that relied on pressurized oil fail. I repeat, A part. Usually a single rod bearing, which I attribute to inconsistency of tolerances in mass production. Total lubrication failure shows up on multiple parts. NEVER changing oil or letting it get almost empty usually causes a camshaft to seize in the head on a modern engine. Not changing often enough causes problems with cam chain tensioners and VVT systems. The factory recommended change interval is meant to get the engine to last through the warranty period. After that 3,000 miles is right for short trip driving and 5,000 for mostly open highway driving. I've owned all kinds of cars and trucks since 1966 and ALWAYS changed my own, plus thousands of times on customers' engines.

  4. I work at a dealership and we always do 5000km ask any mechanic I have seen what’s happens people don’t change the oil until like 10000km and it cost a lot to get fixed

  5. The report does NOT address the language in most manuals that cover first the recommendation for NORMAL DRIVING CONDITIONS…. then they go on to list HARSH conditions that would indicate more frequent oil AND FILTER changes, which include: High Altitude, Low Altitude, Coastal, STOP and GO driving, high speed, low speed driving, hot summers, cold winters, lots of steep hills, Right Hand Turns….. ok…. they do NOT mention lots of RH turns…. but the list covers most all of North America, and most all driving habits. Also, they list cars that sit for part of the year, not driven regularly…. So, I am not likely to go 10K MILES or a year… but 6 Months/3000 miles is fine. As long as one goes to a trusted mechanic, it is GOOD that they have a change to look the vehicle over, make sure the hoses and belts and all the rest looks good, no visible leaks etc. A MECHANIC will likely do an oil change SLOWLY, compared to the 5 min oil change scheisters…. which allows much more old oil to DRAIN while they inspect under the hood and undercarriage area.. less rush, fewer cross-threaded or over-tightened oil pan plugs. I would rather use normal PETROLEUM based oil, slightly more often than some snakeoil made from unicorns and rainbows, and stretching out that service to the last mile before disaster.

  6. Wow 6 diff dealerships wow that's terrible. Also we are trying to keep your car safe not upsell crap. I don't want to share the road with folks who have unsafe cars this is more important than anything else

  7. I do my own oil changes every 5,000 miles and never have any issues….. Ofcourse I'm also dealing with Texas heat so it's advisable to change it more often…… Believe it or not it's not that expensive to do it yourself…… Only spent $26 yesterday to get the oil and filter for my Jeep and then I hopped under and changed the oil….. So much cheaper to do it yourself and then just take the oil to be recycled

  8. Am I the only one that "heard" the answer directly from the owner's manual? Change the oil at LEAST once a year. This means that 2 or 3 times is OK because they are more than once, which is the least number recommended.

  9. It is ok for engines. In Europe most cars are in long life regime. Every 30 000 km oil to be chenged. But engines are scrap after 150 000. Personally i chnge between every 10 000 – 15 000 km.

  10. They tell you, you can go longer on an oil change so it wear out faster !!! They don`t want cars to last past 150k .

  11. It's basically a trade off of protection and cost. The manufacturer's recommendation is not "bible". They pick a point where most daily drivers can safely use the engine until the end of typical car life (like 150k miles). If you change it more often, the engine will last longer, but you end up paying more for the oil changes and you will also need to deal with other parts like transmission, suspension, etc. So it depends on the driving habit and intention for the car. If you race the car all the time, or are willing to keep the car to 200k miles or more, do it more often will save you a lot on engine rebuild. If you are with a daily car and only planning to drive it till it starts to be problematic, follow the manufacturer's recommendations would be best.

    Similar idea goes with the "lifetime transmission fluid". The logic is simple: if the tranny fluid is not changed, it will last 150k miles. If it's changed every 40k miles, it will last 300k miles, but changing the fluid and filter cost money. So it's your choice.

    At the end of the day, this rule never changes: mechanical parts always benefit from prime quality lubricant.

  12. If your engine is GDI or turbo charged change your oil every 5 to 6k miles even with synthetic! The fuel dilutes the oil way too much once it gets to those mileages. So now your 5w30 is acting like a 5w20 or worse. Blackstone labs has verified this on some of my used oil samples with only 4k miles on it! Bottom line do not count on that OLM the manufacturer puts on your vehicle. They want your engine to wear out faster so you can upgrade to a newer model or pay their service dept to put in a new/rebuilt engine.

  13. cbc is giving people bad advice, you need oil changes to prevent engine damage and if you wait as long as the manual tells you you’ll wear out your engine prematurely.

  14. A story on oil change specialist I've had trouble trying to get my brand of oil got ripped twice in 30 days

  15. You also have to realize, they engineer those parameters on changing you’re oil to where the motor will where out around 200,000 miles and then you need to get a new car. You’re best off replacing it every 3,000 miles or 3 months.

  16. Manufacturers long ago figured out "what warranty their giving you and YES they are doing what every other manufacturer is giving"
    (X miles or X time) Period! So, They know how long the engine will last for; X time or X mileage with basic services.
    Then when the "warranty" runs out…. So will the engine shortly after!

  17. Run synthetic name brand oil and change it every six to seven thousand miles, you'll never go wrong doing that.

  18. Get a little dirty and change your own oil. Then you'll know the job was done as well as done right.

  19. Months like 3 is BS. Miles =king. With that being said check your oil level every few K if you're going to run over 5000. Also be sure you are using full syn oil for 5000+ oil changes.

  20. What a complete waste of time. If you drive your car hard tow or drive in heat, it’s water. I don’t know why I even what this crap.

  21. I've always been told every 3 months or 3000 miles now my 1987 Toyota pickup I had years ago said every 5000 miles in the owners manual.

  22. Run full synthetic every 4500-5k miles (actual). I never go by the dash indicator. I use one of my (trip A or B) reset at the oil change. Then I can monitor the miles.

  23. When its not running smooth thats when i change it and normally happens after 2000k kilometer. Thats how i pamper my engine

  24. You may be right, my car takes synthetic. I drive a Honda, for longevity of the engine I just change it at 10%.

  25. Listen to these guys, change your oil once a year! Think that you're being scammed by frequent oil changes, I'll be happy to install a new motor in your car😳

    Why there's a national average of 3k change intervals? Because of old habits. Like the equivalent of putting oil in the oil filter before screwing it on lol, its unnecessary but old cars had inefficient oil pumps pre 80s era, driven by rotating lob, plunger style pump.

    Most cases today, cars oil are changed at 6500 miles in America,however this number drops as vehicle millage increases because of Clarence issues, wear and tear in engine.

    Besides, it's already bad enough people neglects other things and come in with a grocery list of issues. So to add engine issues to the list because in infrequent oil changes is nonsensical

  26. Many manuals show 2 different oil change intervals . The one for severe deriving conditions such as for mostly city and short distance driven vehicles is generally 6 months or 10,000 km/ 6,000 miles whichever comes first. Pls check your manual thoroughly.


  28. 2018 Toyota RAV 4, brand new….was told to change oil at 15,000 miles….went in at 5,000 anyways…..their own mechanic told me I did the right thing….

  29. so we ignore the system notification when it comes up on the dash.. it didn't mention type of oils used like synthetic or just regular .. what's the difference in that as well?

  30. Oil change intervals save you money. The used oil however is purchased from service centers for about $1 per gallon. The service center makes that profit but used oil then is not wasted by any means!!

  31. I change mine every 6000kms – 7500kms – which is once a year

    BUT I drive a Volvo 240, its old and I do it myself, so like hey I can put the best stuff in there and it wont cost me a ton of money

  32. Newer more efficient engines, advancements in engine oil both allow for longer oil change intervals.
    If you consider your vehicle being used as an average driver, my recommendation would be :
    Conventional oil – 5,000 km or 10,000 km for Synthetic. (who cares about 3mth 6mth or 12mth)
    Short trips in the winter, pull a trailer or operate in extreme conditions, consider changing your oil more often.
    Keep in mind engine oils are a blend of lubricants, detergents and seal conditioners, as the engine
    additives break down your protection diminishes.
    Oil companies don't drill 5w-30 or 15w-40 wells, and if its a synthetic oil its life began as a heavy oil
    such as that derived from oil sands.

  33. Every 3 thousand miles or every 6 months with Synthetic oil! No if and or buts. Oil for car engines is like water to our bodies!
    It's so cheap! Engines are not. I've been taking engines apart for 30 years, I see what not changing your oils does to engines! Compared to well taken care of engines.
    Owner's manual recommendations are for your car to fail, not last. Car companies want to put you in a new car every 5 years! Take care of it better and I guarantee you'll see results!

  34. I bought me second car 3 years ago .A 2000 Toyota Solara it had 172k on it.I changed the oil only last Mont at 284k.Oil changes are for wimpy cars.

  35. I think oil change depends on how often u use ur vehicle and I think what the manufacturer means is within that  year, one should change the oil of ur car, could be 3 months 6 months  but do it before that 1 year if it needs oil change. if ur car has an indicator and that indicator turns on I recommend u change that oil.

  36. follow ur manifacturer instructions manual on what type of oil to use on ur  vehicle make and model.u can ask the shop u take ur car for an oil change that u woul like to use the oil recommended by ur manufacturer.might be more expensive but will make ur engine run better and longer.

  37. one has to follow the OBD1(onboard diagnostics one) system for cars 96 and older you want to change that oil when it says so on your windshield I agree but if ur vehicle is within the OBD II( onboard diagnostic 2), 96 and newer change ur oil when that indicator tells u too.newer models are made with sensors for the oil that sensor is connected to that indicator that turns on when that oil needs to be changed.

  38. im not the greatest mechanic out here,but I know about an oil change im a certified mechanic from CET AUTOMOTIVE(automotive specialist)I specialize in brakes,steering,and alignment,but I took my classes in everything hands-on training and the book,i have over 7 years automotive experience.dont know much but know the basics,and believe me 60 dollars is a lot for me for an oil change!but with a sixty dollar oil change I would check all liquids without charge and would tell my customer an estimate of what ur car needs and why even put on board the computer for free no charge.

  39. $100!?!? Just do it yourself. You can put the best oil in your car for $30 plus the cost of an oil filter. I definitely would not go a year without changing the oil though. With full synthetic, your safe to change it every 7,500 miles.

  40. Go by your owners book clear and simple my last change I put mobile one oil in my sub it says I can go up to 15000 miles before next change and that's why it cost more I hear it's the best to buy for your car do I did very nice start after start

  41. I call bs i recommend sny.oil and change it every 6000 new engines with all the timing chains and their tensioner tell a different story if you dont

  42. its cheaper just to change the oil yourself its less than a hour and its never a bad thing to do it more its cheap and does not take time its the best thing you can do to keep your car running longer

  43. I always love these type of people. They change their oil once a year then cry about it when they have to replace their engine due to engine failure. There are interval options for mileages in easy climates vs extreme. Extended idle times vs mileage.

  44. Old news….I use OW20 synthetic oil for my 2012 Corolla and change my oil every 9,000 miles. And I have read I could change it 12,000 miles

  45. Buy FULL SYNTHETIC you'll get 2x the protection and 2 or 3x the mileage… ie. 7 to 12k miles. Should depend on your amount of highway miles. More than half of your miles on the highway you can go longer on your oil. Always check your oil every 1000 miles or so and top off as needed. Full Synthetic dosent break down nearly as fast as regular oil. Superior protection. Also important to use premium oil filters. KN, & PURALATOR are very good.

  46. Only 1000km on that Jeep's oil? Of course, it's still good! That a fair comparison to the other cars in the video. I would've liked to see one of those other 5 cars have it's oil analyzed.

  47. simple learn to do your own oil changes, and if you use 0w-20 "full synthetic" do your oil change every 5k miles or every year witch ever comes first . If you use conventional oil, do it every 3k nmiles.

  48. Not here to dispute anyone's point of views. Just want to tell you what I had learned from a friend of mine who is a retired mechanic for the Canadian Armed Forces. This is what he does: pulls out the dipstick, rub the oil on his fingers; take a sniff and notes the color of it under a bright light; then he determined the oil was still good for the time being.

  49. hotter than the sun? Anyway just use common sense. Do my own … not rocket science and done right …don't like it when they through the bung back in after 5 seconds while its still draining. All depends on the vehicle u have and how u drive it and WHAT oil and the QUALITY of oil u put in.

  50. Eh, still gonna change the oil myself ever 3k miles. I drive her with intent and fun, so better to be safe than sorry.

  51. Once every 3 months or so, that is between 5 and 6000 miles for me, I go to the parts house and I'll buy the oil and the filter and it comes with a drip pan and 4or5 shop towels and a funnel and I get everything for about 30 bucks. I watched about 15 different videos on YouTube and learned to change my own oil. Way better than giving 80 to $90 for an oil change.

  52. I'm pondering doing the recommended 10k full synthetic oil change on my 2016 Tundra.I pull alot of trailers,hual loads up hills? Check us out finding gold and many adventures 😁

  53. Once again CBS leading people wrong. Have you ever seen inside an engine that does 1 year oil changes?
    I have seen it. The extra sludge build up cause 75% of engine fails due to oil sludge build up where oil needs to travel better for lubrication.

  54. Soooo the Builders "Marketing Ploy" Would be 2 get u 2 Come in "Less" for Oil Changes?? Why "Lady Mechanics" Playing Receptionist?? 🤔🖕

  55. Well when it starts turning black it does thickn and looses lubrication properties but not enough to make any difference. The longer the oil is used after it turns black, the worse it gets at protecting an engine. So I'd say to be safe every 5 thousand miles for conventional oil and every 8 thousand for synthetic, that's for all city driving in average conditions. Now Highway driving with synthetic oil I'd say 10 thousand miles and 7 thousand for conventional oil given you live in a mild climate. This information is confusing because everyone gives different answers but I'm just telling people with a straight answer no nonsense. Hope this helps

  56. It all depends how you drive a car or truck . Just like a tire or brake pad that would wear out faster on aggresive driving or harsh climate. On top of all those how do those car manufacturers make money? By selling stuff or making your stuff last longer where you won't need thier parts service or even a new car .
