I went to Autozone and had to try this thing out. Everybody has been praising it so highly. The car is a VW GTI 1.8T AWP. Currently running M1 0w-40. The guy at Autozone pricematched Kragen's coupon for $1 off a quart on Castrol Syntec, and also gave me the Autozone Rewards Card. I think the bottom said 0502..., but when I shined my flashlight in, it looked green to me. The M1 was yellow. Do you guys think its going to be in Nevada heat? I mean, if the M1 thins down, and the GC thickens, I figuered I should be ok.
