Does it work? How would I know?
What can I say? I buy it because of the reputable name, and I know of no cases where a motor has failed because this oil was used. I have strict requirements from my oil - it must keep my engine running well until I either destroy or sell it. Period.

PROS: No assembly, Portable, Works inside and outdoors, Doesn't smell bad

CONS: Tastes AWFUL, Messy if spilled, Pricey

Can't go wrong
I use this in my ninja 1000, and all my 400/450cc dirt bikes for the last 13 years. Oil maintains its consistency even if I go longer than I should between changes. Never had any issues whatsoever.

PROS: Runs Clean, Always Consistent

Smooth shifting
Used this when changing out full synthetic in my FZ1. So far I have noticed improved shifting performance vs the old oil, other than that it seems to lubricate like oil should!

PROS: Improves Vehicle Performance

Perfect for the streets of Vegas
I would definitely buy this again...I always do anyway. It works great in the summer time in Las Vegas. It's a little heavier and it just seems to feel smooth.
