"I have just ordered 2 pails of . There are alot of Z33 racers that use this in japan and think its the best thing. I thought I would try since its only $55 for 5gal. and the viscosity test where better than Mobil1. The only thing is that no one in the US sells it. So you have to import it." The above is an excerpt from a G35 forum. I had never heard of this oil so I figured that this is the place to ask... who's the resident expert on the above?
