I bought a hone and the oil last week. Got to use it last night. it worked great. my yz250 cylinder looks like brand new inside now. Much easier than going to the dealership. i think i will start charging my buddies!

This is the only oil Ive ever used where I can actually tell a difference in the way my bikes run. Ive been using it in both my street & dirt bikes for a couple years now & wont use anything else period. Expensive , yes a bit but so are engine repairs. Cheap insurance to me.

I have 2004 SUZUKI DR-Z 400E...I ride hard in the woods and far. all i used is this Castrol Act Evo 4-Stroke Motor Oil 20-50 in my bike,, At 10000 miles, i had to instal a new Cam chain and at the same time why not replace Piston ,so i did..let me tell you, all of the Engine components are in specs, no wear ,,this is great oil.---always do your oil changes often and clean your air filter and use this Castrol oil
