Engine oil Shell or MOTUL

I use Motul 8100 EcoLite in mine. Paired with the appropriate Motul fluids in the trans and diff, and RBF660 in the brake lines.

Motul 5W-30.

I'm running 10w60 MOTUL 7100, I sit on the revs though, always Tach out!

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.

I recommend Motul and I advise tou to never use RS8, it's a rebarded Xhina brand.

Shell Advance Ultra - yung full synthetic. Mahal pero worth it. I change oil every 2.5k - 3k max.

I was at LordCo recently and one of the workers was going off while i was looking at Motul.

I have been using Shell Rotella T5 for decades in big v twins. Currently 1900cc Statoliner.

Im with all these 5w40 rotella guys, just started running it in my 91 1500 with 145k miles with the 4.3tbi and she loves it, I notice a slight bump in oil pressure for sure.

I used Motul with ester. 15W-50 I think? It was for a 16’ Continental GT. Seemed to work fine.
