Subaru Impreza

Review
Brought my car up for trackday last weekend, but only after hydrating it up with these awesome goodness: the Power Up 10W-30 SM/CI-4! I notice a much more responsive engine and gearshifts, which just makes my trackday a satisfying one. They are really something most track junkies would love, and I think they wouldn't go back to any other after trying it, like me. I just couldn't get enough of the oomph it is producing. Would definitely recommend to the spirited drivers out there!

What I like
Provides the ability for the engine to response much more promptly and smoothly!

What I do not like
Slightly expensive than the normal performance engine oils.
