Owner reviews for engine oil

Mobil 1 5w50. Temperate climate. Car always garaged. Annual changes at 4000 miles. Zero top ups required.

I run 5w30 in my 17 tundra, 16 Corolla and soon my 23 4Runner. My Tundra was noticeably quieter after the switch. The Corolla was quieter, but the change was not as dramatic as the 5.7 V8 in the tundra.

Liqui Moly Leichtlauf High Tech 5w-40 and 450ml of Liqui Moly MoS2 anti friction additive.

Good results with Castrol Edge Euro full synthetic. No issues. 138,000 miles, no oil consumption or smoke.

Dt 40… also use motul xcess gen 2 in the 986, the cayenne and a couple of bimmers. Blackstone reports look g great with all of them.

5W50 Liqui Moly on an engine with 156k miles on it.

I’ve used Motul, LiquiMoly, Molygen, and Redline 5w40. Oil analysis was best with the Redline, but it’s pricey…although worth the better numbers IMO.

If in Europe use Aral Hightronic 5W40. This was the best oil for my A4 130PD TDI.

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

my valvetrain was always noisier when I used to run Mo1 0w40.
