Valvoline Max Life oil

does valvoline max life - high mileage oil help me at all or should i be using any type of oil?
my car has almost 300 thousand km on it.

it's all by opinion.

yeah i just wanna know what everyone thinks =)

Regular dino Castrol GTX 5w or 10w30 FTW. Seriously though, its all opinion like the man said, plus how much oil you burn.

well i used mobil one but now i use royal purple(in the rex).
in the prelude i use regular mobil, or castrol what ever i feel like at the time.

i used max life in my civic...but other times i used autozone oil b/c i was going thru it so quick
