I like changing oil only because I usually don’t get to work on cars much, which I like to do. Plus I inspect stuff.
My van gets a 6000 OCI, which is below the OLI, but above my desired 5000 miles, which I extended after spending time here. I’m on month 6 on a change now and almost to 6000 miles. It’s also our “nice” car, having only 88k miles on it.
My Camry will get its first change by me around 4000 miles due to it having the trade in dealer fill in it now, and that will even up the miles to 230k. I’ll probably run 7500 miles or once a year on it due to the 22 miles per day it gets on my commute to work out in the country. It’s a commuter beater, and nothing more, though I don’t let maintenance slide, even on beaters.
My daughters Bug will be once a year, as miles will be low, but harsh due to shorter trips.
The Jeep is once per year and I may be rebuilding the engine next year if my annual bonus is good. 251k miles on the 2.5l, and idle oil pressure is just under the 10 mark on my mechanical gauge
