Owner reviews for engine oil

Not saying it is better than anything else, but on my G60 turbo i used Mobile1 FS-X 5w-50 and will continue with this oil on my PG/ABA turbo.

Redline recommended 10w-40 Full Synthetic for my 1.8 solid lifter JH turbo application and the tech guy suggested modern synthetics don't cause seal leakage (like OG synths of 25 years ago) and holds up way better than the 40w rating in hot temps and protects much better when cold than even the current crop of Castrol 20/50 dino oil I was running. I swapped over the M81 to the same Redline oil and have not yet noticed any new oil leaks yet.

I ran Mobil 1 20w/50 for 24 years. The guys at NGP use Liqui Moly everything so I switched after reading up on it. I'm REALLY liking Liqui Moly since I switched 3 years ago.

I'd go with [Liqui Moly Leichtlauf 5W40.](https://www.fcpeuro.com/products/vw-oil-change-kit-5w-40-liqui-moly-kit)

I use Amsoil 0W-20 (also on my 2020 Audi Q3) since it meets the specs.

I don’t use the Mazda-branded version, but Idemitsu is my go-to oil in all of our Mazdas

0W-30 VW 504 spec Penzoil Euro Platinum is all I use in my MK7.5.

Pennzoil has been pretty good to me. Not pushy.

Total quartz is good

Valeo from FCP Euro, lifetime warranty on almost everything including oil, great company, already on my third free oil change with them
