Engine oil VALVOLINE or MOTUL

Now if you were to get Motul 300V, there would be a real difference there. Higher end “boutique” oils have additives, such as esters that will build up a film on moving parts over time, adding a layer of protection if for some reason you were to lose oiling to that part.

I used to run the 10w-40 Valvoline high mileage synthetic blend from Walmart.

Motul 8100 x-clean 5W40 seems to be the sweet spot, all of my friends drive it in EA113/EA888 engines.

Other Euro brands such as Castrol or Motul are also fine choices

I used Motul and it made shifting noticeably better

I used the Kawasaki 10w-40 for the first year I rode mine, it would always have an odd mis shift here and there. Last year I used Motul 7100 and it made a huge difference, way less shifting issues

If you are considering an oil additive, best practice is to instead use higher quality oil (I like motul) and select one which matches your use case.

I use conventional 20W-50 VR1 for oil, love it.

As a Shop owner that Services a ton of Euro Cars we pretty much use all the Valvoline Euro Spec'ed Oil. They meet all the OEM requirements as we've also sent it in for testing. I have a 2014 CC APR Stage 3+ and thats what I run, Valvoline 5W40 Euro. No Issues.

Valvoline vr1 20w50 I'm convinced they basically make it for rotary's to begin with.
