Time or Miles Longest You've Gone wout an oil chg?

[Ducked]

Think its currently about 4 years on a roughly 50:50 accidental blend of CPC straight 40 and Mobil Delvac 15/40. Very low miles.

Looks OK but I have no UOA data and aren't likely to get any.

3 or 4 years technically, the car burned so much oil that really i almost didn't have to change the oil.

My track day car, never had a single "oil change" in 5 years; went in for lots of [partial] engine rebuilds though and got fresh oil each time

16 months and 57k miles into my current run. I'm running a dual bypass system, with Amsoil Signature Series 5w -20

5 years and 1800 miles on my 92 Suburban. M1 oil was still fine.

Went 21k miles on conventional in my 2002 Cavalier; even posted a UOA here, but it was more than 5 years ago so cannot post link to it.

Oil actually didn't do that bad, considering.

5 years on low mileage/use pick-up.

When I was a teenager in the 1960's some cars never got changed. Just topped up every few 100 miles
