Engine oil VALVOLINE or FUCHS

I use Fuchs Titan SuperSyn 5W-40 - widely considered to be the lowest-consumption oil for the M54 engine, and it's very cheap.

Mann filter.

As a Shop owner that Services a ton of Euro Cars we pretty much use all the Valvoline Euro Spec'ed Oil. They meet all the OEM requirements as we've also sent it in for testing. I have a 2014 CC APR Stage 3+ and thats what I run, Valvoline 5W40 Euro. No Issues.

Valvoline vr1 20w50 I'm convinced they basically make it for rotary's to begin with.

I've been using the valvoline personally and like it better than the pennzoil platinum.

Used this for years in my 4 strokes. Quality oil.

I run valvoline in everything I own wether it’s diesel or gas. I used to use Rotella for my truck and pensoil for everything else, but valvoline seems to make it all run better and smoother

I run Valvoline blue and love it. Run it in my IDI and my 454 Burb

For the last 17 years I've run the recommended Valvoline Blue in all of my Cummins and so far the internals have been spotless when looking inside.

'03 GX470, had 240K miles when I bought it just over a year ago. Now on my 2nd oil change at 245K miles with Valvoline High Mileage 5W-30 full synthetic and Fram XG3600 filter. It's quiet and doesn't burn or leak oil.

Valvoline Advanced with black Wix filter!
