motul is the right brand to use.
if u think 300v expensive, you can consider motul 4100.
i am using Motul-4100, change every 3000km.
no joke, the oil temp drops significantly since change to Motul-4100. (sorry as i cannot remember how many degree it drops)
there are so many brands in the market. stick to motul, you can't go wrong.
the reason i do not use 300v:
1. very expensive.
2. much much costly if change at every 3000km.
3. it is "thinner" so less power loss. you feel more power. i believe it is expensive because it gives similar protection even though thinner.
4. i found out motul-4100 giving lower oil temp as well, more affortable, thicker means good protection.
btw, mine is evo8mr, not an evo-x ...
