I've heard that Schaeffer's 170 Extreme Performance 75w140 would be a good option for the troublesome / half qt capacity / no drain plug transfer case of CX-9's. Looks to be good oil but I can't find it locally and the shipping online is outrageous. Would it be worth it anyways since I could get two vac and fills out of a single quart? Anyone here have any experience with it? Currently running RP MaxGear and it comes out terrible everytime. Looking to step it up.
