Owner reviews for engine oil

Been running Castrol in my VWs for 20 years. Never had any issues.

I have use Amsoil European since new! 185,540km so far, and still purrs like a kitten, does not use oil, and the oil is highly rated!

Castrol euro has been good to me for the last 120k miles.

Great oil, I go with the Ultra Platinum. So far it's been the absolute quietest (based on subjective valvetrain sound) and smoothest driving oil I ever used. I tried OEM, Valvoline, Castrol. Nothing was as smooth as the Pennzoil even after a few thousand miles. I still change it every 5k for peace of mind.

I switched to Rotella about 15 years ago after it worked good in an ej22 that was averaging a quart every 300 miles.

I’ve have always used higher quality oil like liqui-moly (0w-20 till 60k kms)

I might add use the best oil you can find - this will keep your PCV system spotless and other good things. I always use oil to the severe service Volvo spec listed in the owners manual. I now am pretty exclusive to the LiquiMoly line. I insist on 3rd party certification

I use Amsoil 20w40 in all of my semi truck motors. I change it according to what the lab says the condition of my motor and oil. I am going 100,000 miles on my over the road trucks. I go 25,000 on my power stroke and could go much farther.

I use mobile 1, 0-20w in my 5.3 GMC. 3k miles every change w filter. In the colder months it looks brand new coming out. Little bit darker maybe. My most recent change with the past month being 85+ I noticed it finally being very dark and red.

5w30 pennzoil, doesnt make the vtc rattle with that oil, mobil 1 sucks i would stay away from it it also burns much faster
