I haven't used the BG MOA but use the BG Coolant and BG Synthetic trans. fluid in two '04 vehicles. The one that took advantage of the $2,000 BG trans warranty wasn't the one that I expected it might be. Only was a few hundred dollars for out of pocket cost for a complete rebuild and the work was done at the best shop around. I use BG 44K once a year and Mobil 1 at about 4,500 change intervals when it is starting to change color. Both run fine and the Tahoe waterpump and intake gaskets are covered by the BG warranty. BGFINDASHOP.COM for someone near you. Thanks. *BW*
