Incorrect. They do monitor, in the higher-end cars.

You can check the oil itself, and it's possible to look around just see if there is any sludge.

They inspect everything these days. If you can't prove you did your maintenance and they think there might be a problem....

You'd be surprised at how incredibly technologically illiterate some automakers are.

Not really. You get charged a hell of a lot if you don't return it in good shape.

My point about looking in the oil fill hole is to look for sludge build up or lack thereof, on some cars you can see the cam, since you are looking right at it you might as well see if you see any scoring.

I didn't say that old oil caused camshaft scoring.

If you are looking at a car to buy, generally you can't tear the engine down and mike everything - would be great if you had a way to do it but it's not in the cards. So instead I suggested a simple inspection that you can generally get away with doing.

That said, some cars have a baffle under the cam cover and you can't see the cam, but in general I do take the oil cap off and take a look on a car that I am considering buying. It's not a definitive test but it's easy to do and you can tell if an engine is clean or dirty internally.

Well I asked 7 people at work who only lease cars. None of them said they ask for service or oil change records at turn in. So theoretically you can lease a vehicle for 2-3 years and never change the oil. And the engine would still run decent.

And whom do they lease them from? Do they service at the dealership?

If so, then they have no need to ask for records.

If not, then they probably wouldn't ask unless they noticed a problem.

And the engine would not run decent if you didn't change the oil for 3+ year, or 30K or more miles.

yes, of course, coz they requires we perform the scheduled maintenance in timely manner, even not go to the dealer but to somewhere outside shop for Oil change, we are required to show them the receipts as a proof when return the car.

So far they accepted and has no problems with this. I lease cars more than 10 years...

No servicing at the dealership (too expensive). But I bet you I can lease a brand new car today and drive for 30K miles without an oil change and turn it in and dealer would not have an issue with the engine.

Give it a shot. See what happens.

By the way, the dealer has nothing to do with lease returns other than a drop-off point.

They may be visually in good shape, but a leased car is less likely to have been pampered. There's no way to know how many times the engine has been red lined or how much wear the transmission has just by looking at it.

"Eh, I'm not keepin' it, lets see how fast this thing will do 0-100" .
