Reviews of Shell parts For Business

dude stick to the engine oil grade mentioned in the user manual and fill shell synthetic of that grade

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

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.

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

I did use the Shell T6 Rotella 5W40 for 4 OCI's and then got a misfire issue. When my mechanic was going thru the possible symptoms he asked what oil i used. When i told him it's a full synthetic deisel truck oil he shook his head and said that not a good idea. Too thick, and that could have an impact.
