Engine oil VALVOLINE or Shell

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.

As long as you’re not mixing fuel with it you’ll be fine. All of my stuff runs on basic and cheap T4 Rotella 15w-40. Have never had a single issue

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.

Rotella T6 full synthetic, zero problems, never let me down.

Rotella t6 never let me down cannot get it so Schaeffer's it is. As long as you change it you're good. Schaeffer's has a 5w40 which I like because I see thirty below in the winters

Rotella T6 15w40 is like franks hot sauce, I run that shit in literally everything. Civic, VW tdi, cummins, generator, even my KTM 450 dirtbike. I’ve owned the bike since new and for a very high performance engine at 120 hard hours it looked nearly brand new, I’ve never seen an oil perform like that.

Rotella T6 5w-40 and it’s finally easier to find now!
