Owner reviews for engine oil

The best oil I've ran till date is LiquiMoly

I drive a German car so I run liquumoly molygen or Motul Xcess.

My Mazda3 which I service myself now, Castrol edge 5w-30 and feels happier. Same engine too.

I’ve had good luck running Valvoline VR-1 in engines with flat tappet cams.

Valvoline VR1 in whatever viscosity is suitable for the season and the VR1 has plenty of zinc for old engines.

I always used blue "german" coolant in my e90 bmw oddly it also recommended Castrol oil. Specifically called for it in oil cap

Switched to Liquid-Moly and had good results.

It gets regular 10K oil changes with Liqui Moly Top Tec 0w20, and doesn\u2019t burn a drop between oil changes.

I have been running Motul 5w30 Xclean EFE and have used Pennzoil Ultra Platinum as well.

Voyager Silver is a Sh*t quality oil. Stated as 10k kms oil, It's roughly equivalent to a 5000 km oil, effectively.
