Engine oil Shell or Mannol

Rotella 5w-40, for no other reason than it is good oil that I can use in every internal combustion engine I own, including wet clutches.

I've used for the last 20k miles and no problems! Just change at 5k.

Rotella 15w40 for mine. Never an issue and good oil reports for several hundred thousand miles.

Rotella T6 has been good to me.

Shell Rotella T6. It's marketed as heavy diesel oil, but it meets the exact same specs as mobil 1 full synthetic and just has some extra detergent like diesel oils do.

This oil in OG 9-3 that have the crankcase retrofit kits clean the entire engine very well after a few oil changes getting rid of and preventing any sludge issues. The oil even eliminated some nasty tappet noise due to low oil pressure in my 2002 9-3 after a few seconds when I bought it.

I just hit 19k miles on my 2017 390. I ride it like someone stole it. Also thousands of high revving miles on the highway.

I use nothing but Rotella T6 15w-40. It is really good oil and it is cheaper than almost anything else you can use.

Shell Advance Ultra - yung full synthetic. Mahal pero worth it. I change oil every 2.5k - 3k max.

Also been using Mannol. Do 6k oil changes though. Made chain noise on start up. Swapped back to mannol noise gone.

I've used Mannol for a few years, it's dirt cheap here in the UK and I've never had any issues with it.

I think factory recommendation is Rotella but honestly you can go with any high quality oil. I have used Rotella, Castrol, and Valvoline synthetics in my 500 and I honestly don’t think it matters.
