Highest miles on engine using 0w20 or 5w20

200k on Kia Forte 4 cylinder before transmission took it out. Was stolen at least 3 times.

Yeah, but had you used a 5w30 oil like the engineers truly intended, that tranny would’ve lasted a nobody would’ve stolen it.

360K on 04 Ford Ranger 3.0 vulcan, 5K OC of MC 5w20 syn blend until 3 years ago. Now it's getting Super Tech 5w20 syn blend since MC decided they don't want to sell the oil due to the $10 price increase for 5 qt bottle. If Napa's syn blend is on sale cheap I'll get it.
