If you want to go a whole 3 yr 36k lease without an oil change and roll the dice on engine failure, you are dumb. If that engine blows for any reason and its due to lack of maintenance, the leasor is on the hook for that damage. They sure as hell won't cover it. They won't have to drop the pan to figure that out either...People are mind blowing dumb. Now if u managed to make it in sure they won't usually check, but that's a scary ride for a few 29.99 quick lubes.I bet this is a lot more common than we think. There's a lot of people who lease cars, make the payment every month and turn it in at the end of the lease without doing anything.
Our recent experience returning a leaseon certainly makes that easy. They didn't ask for any maintenance receipts and didn't even care that it was in a pretty substantial accident. Knowing that, the current one is going to get the correct oil, but it's getting changed once a year and that's it! Not doing every 6 months.
