1970 VW Beetle - 127,562 miles - Was in for somewhere around 1 year and 1,300 miles. Was pretty dark with quite a bit of dirt in it. Spotless under valve covers though.
NOTE: Very easy oil change--due to the height of the truck, the cartridge filter is a reach (on top of the engine) and requires a step stool to stand on to get to it.
2001 ES300. Doing a really short OCI for now, as this engine is a notorious sludger and I don't know the history for the past 100k miles.
Only 1300 miles on since my last change from a month ago (though posted here a few days ago).
Out: Mobil 1 5w30 High Mileage w/ M1-102 filter
In: Wacky mix of oil, most of which I had left over for topping up my old now-totaled car. Wanted to get rid of all these random bottles, though now i have 1/3rd of a bottle of TGMO left >.<
