Engine oil MOTUL or AMSOIL

5000 miles with a quality full synthetic will serve you well for the life of your vehicle.

Motul 300V 15W-50 In my "circle" it is used up to 1200+ HP.

Maintenance, that’s what I’m focusing on rn so far ive done oil and coolant, went with amsoil and Nissan blue

I used AMSOIL signature, and do yearly oil changes.

I used Amsoil when I did mine. The squeeze bags they have make changing the fluid a lot easier and it's good oil.

Aside from the sodium levels, which they mentioned they aren’t really worried about but to check my coolant between changes (which I do and I’m not losing any). I feel pretty good about these results!

Motul 7100 10 w50 good after using 4000 km

Motul 7100 4T 10W-50 i use this and it's pretty good

I just use Kawasaki mineral oil or the Honda/Yamaha similar. Never had issues. Tried motul, liked the smell, same performance, more expensive, no point for me.

motul 8100 is defenetelly worst oil you can use.
