use 0W40 for the past 4 years, tried TCM Shogun, Carlube, Agrip, AMSoil, astro boy, valvoline and other brand that I cant recall.
Best experience : valvoline (with engin flush, autosaver) then astro boy.
If I mainly drive in city with W40 oil then full tank can reach ~300+km
Highway within speed limit can reach 500+km per tank.
