Engine oil PENNZOIL or MOTUL

I just run Motul. 7100/7200 or the 300v.

Years ago I went down the oil rabbit hole and now I recommend motul 7100 4T

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.

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

I personally like using pennzoil euro platinum 5w-40 in my Mk7.

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

I've run Pennzoil Ultra in 5W-30 for the past 4 years and never had a problem.

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

Some 5w-40 can be quite thick in cold. The 0w-30 here is German Syntec, and trust me it's the same visc curve as 0w-40. As you see, 5w-40 is 3-4x thicker in cold than jug 5w-30
