There are the recommended motorex formula 15w50 and other options for 390 engine. It seems motorex formula is thinner and has lower TBN than others. I ended up using 7100 10w50 for the next 2 oil changes.

Thanks for putting this together!
No problem my friend, I just made up my mind using motul 7100 10w50 for next couple of oil changes since it is thicker than motorex formula 15w50 at all temperature. And I am not a fun of Repsol, Castrol or any other European brands so they are excluded.

I am always a big fun using American products. but the KTM shares the same problem of European cars of using rare viscosity oil. I still remember my old Murcury Grand Marquis using conventional 5w20 all year long and run like dream.

Ride Safe.
