Engine oil Shell or FUCHS

Shell advance long ride or power you have two choices for fully synthetic trust me dude once you try shell there's no going back castrol is the worst for Royal Enfield and motul is better suited for high compression engines like KTM etc

Fuchs is excellent oil, run it in my nismo 370z cause it has specific esters that the cylinder liners need. Don't think it's necessary BMW engines but it is very good quality oil.

I run Shell Rotella T6 15W-40 diesel engine oil in my Versys. It has all the ratings necessary for a motorcycle engine and a wet clutch, and it is a quarter of the cost of bike oils.

Rotella T5, up to 14k in between changes per oil analysis. Great oil, never had any issues.

I've used Rotella T4 15w-40 in my 2008 6.7 Cummins year round in Canada. The ol girl has 700,000km (420,000 freedom units) and she runs like a top.

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.

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.

Rotella T6 Full Synthetic 5w-40... Burns a little.
