What truckernix said. Lucas oil stabilizer is a viscosity enhancing additive making the oil "stickier" for it to cling to the gear more. The stuff works well with petroleum based products. I would not use it with synthetic as the synthetic (Mobil 1, Red Line, etc.) already have viscosity stabilizers in them. I myself switched to Mobil 1 trans lube a cumulative 750k miles ago and will continue to switch all my transmissions, differentials and transfer cases to it.
