Engine oil Shell or RED LINE

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!

I use Red Line in everything. The M3 gets 15w-50.

Shell Rotella T6 15w40, has worked fine in my F800GS for 40k miles.

I would recommended shell ultra 15w50 . KV100 is 20 which is thick as fuck and won't shear down quickly. Mogul 7100 is thin and will shear down to 40 grade and internationally considered garbage oil. Shell is made of group 3+ base oil so its going to perform better.

Rotella 5w40 only. I daily and track mine

With the redline, my car barely burns any oil, and significantly less is directed to my catch can. Night and day difference.

On an old e36, 5w30 full synthetic no matter the brand would often cause some leaks. Switched to some thicker Rotella oil made for diesels and suddenly no more leaks.

Redline is what I'm currently using for engine oil, shock fluid, and brake fluid.

Redline 5w-40. 6k mile intervals. Probably much nicer than what my little GTI needs, but I like supporting local businesses and it's amazing oil.
