Hey guys I know there is alot of controversy over the best tranny oil.. I would like to know however what would be better to use if I hadto use one that I currently have in my garage. I have 80w-90 gear oil and 10w-40 Motorcycle oil with wet clutch protection. Which one would be better to use if I needed something in a pinch. I also was wondering if someone could tell me if you need to rejet if you advance the timming on the blaster. Thanks !
