Pony Express Monster Truck
AMSOIL/Turpen Motorsports Inc.

"We put all the AMSOIL Lubricants in the monster truck, including grease in the differentials and transfer cases, and it has freed the truck up tremendously.  It used to get hot after you do a doughnut, but now the differentials are staying cool. Everything is staying ten to twenty degrees cooler than before.  And not having to change them as often is really good.  Now that it's freed the truck up, it's very smooth now, very responsive with the big motor in it . . . It's been a nightmare for everybody we race."
