Engine oil MOTUL or IDEMITSU

Motul 5W-30.

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

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

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

Motul 8100 xcess for high mileage. I've had a few subies thrive on this stuff.

Idemitsu all day. It’s synthetic but what needs to be emphasized is the ingredient blend is purpose designed for a rotary to make the right lube + burn.

I've been running that exact oil in my rx8 for about 1k km now and its still as smooth as ever

I only use Motul in my car, but I only drive enough to really do 2-3 oil changes a year in 3000 mile intervals usually.

Did switched my D400 to Motul 7100 4T 10W-50 @ 8K kms but in a non Bajaj service center.

Difference that I notice:

Engine looks a bit refined and smoother at high speeds or cruising above 70.

I used to run Motul 800, but switched to 710 now. 800 has a higher flash point for high rpm racing, and I was getting carbon buildup from not running the bike hard enough.
