ill have to look for the engine oil, that sounds like that should be fine, but im not sure the make mobil 1 high mileage in 0w30 for the transmission. The reason it has to be high mileage is because of the material the synchros are made of, they require the oil to have a high level of ZDP, 16000 PPM or more. The only oil so far to have that amount is the mobil 1 high mileage, the original mopar stuff, and the higher end racing oils labeled for synchromesh transmissions, although those are usually thicker. The mobil 1 has tested at being 99% the same as the original mopar fluid, which was designed specifically for this tranny, with the only differences being mobil one has a slight increase in ZDP, and a slight decrease in sulfer (which was used as an anti-tarnish agent in the 95 model transmissions with brass synchros)

Thanks for the help, and look for a project log this weekend, ill probably put it in here, since its going to be a combination of a lot of different things, from aero to weight reduction to some new things i want to try.
