Engine oil MOTUL or Motorex

I live in the same area with the same motor and run Motul 300V competition 5w40 on my high mileage track car at the recommendation of my mechanic

Well I decided to try Motorex on my F800 GS, bought the 4T Top Speed full synthetic, in 15W50, boy I cant help it but recommend this oil, the gearbox is so smooth and silky.

I would say 0w20 Motul 8100 is a solid choice.

I use Motul's 0w-20 "Eco-lite" and change about every 4-5 (or April-October really) with about 25 autocrosses and the highway driving to get to them.

I use Motul 300v 0w20, plus oil analysis from Blackstone Labs, currently every 6k miles until they tell me otherwise

Motul 8100 5w-30

Check the oil recommendation in the manual and then go with castrol edge or motul if you want to go the safe by the books route.

Motul 5w40 - shit is so good you can pour it over your salad.

Motul 5w40 every 3500ish miles
