Three things people seem to be ignoring:

One - many casual drivers go over the recommended maintenance schedule. At a recommended 15k interval this could end up being much later, say 20k or more. Some lease cars never get their oil changed (so 30k or more) which can create some sludge problems.

Second, have you seen anything at all about blown engines due to long oil change intervals, cause I haven't. You really don't see this as a way for them to get you in their dealerships more often?

Third, some guy just posted in here that he hit 200k miles with 17.5k average oil change intervals. Others have done oil analysis at similar mileage with only minor degradation being reported.

It's like everyone believes in science and advances in technology except when it comes to oil and then they resort to some strange primitive 3k or 5k oil change interval on fully synthetic oil because that's what their Grampie told them, lol.
