What Oil to Run in 12Bolt
My new 3.73 Posi, Ring and Pinion should be here via Brown today and the guy that is doing the set up for me recommended a 80 - 90 weight oil named Mystick JT7. He said that they have run this oil for years in his race cars and it will make the rearend run much cooler than conventional oils. It is not a synthetic however.
What are you guys running? Would you recommend a synthetic with the locker? It is a Eaton locker. Thanks
