Engine oil Shell or Eneos

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.

My shop has a racing team and I've been using it ever since he got a sponsor.

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.

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