1987 Toyota 4Runner 330,125 miles as I type this. Dealership serviced for the first 255,000 with bulk 5/10w30. Since my ownership its been mostly conventional oil as well with a few synthetic blends and one run of M1. Still consumes no oil.
2004 Lexus ES330. 166,000 ish miles. Family owned since new. With the exception of a few dealership oil changes (2-3) it went the first 130,000 miles with M1 5w30 @ 5-8k intervals with a few runs in there on Redline 5w30 as well. Since 130 k it's had Lubrication Engineer 5w30, VSP 5w30, M1, PUPPP 5w30 for a 10k run and PYB 30 for 5500. Currently filled with VSP 20w50. Also consumes no oil and I've yet to have a UOA with anything but single digit wear metals.
