Hallgren Brothers Racing has been using AMSOIL products in our off road race truck for four years.  Every year, we push the truck harder and harder.  Every year, the AMSOIL products in the truck perform flawlessly.

We use AMSOIL Series 2000 20W-50 engine oil, transmission fluid, grease, Series 2000 75W-90 gear lube, AMSOIL air filters and air filter oil.  Each year we continue to push the edge of the envelope.  We are always trying to go faster and faster.  Each year, AMSOIL is up to the challenge.  The searing heat, revving the engine to 8500 rpm, the mud, the rain, whatever the conditions, AMSOIL performs.

There is no use having a 700+ horsepower engine if the transmission and gear cannot get that power transferred to the ground.  Thanks to AMSOIL, the transmission and gear have no trouble doing that.  Our transmission runs at 220 degrees all day long.  Some of our competitors reach 300 degrees!  (They are not using AMSOIL.)

Hallgren Brothers Racing believes in AMSOIL products.  We punish this stuff...hard.  It is the best preventative maintenance we can do. Hallgren has reduced oil changes to once a season and rebuilding transmissions is a thing of the past. “AMSOIL saves us time, money and worry. The only thing we need to worry about is if the dipstick reads full!”

Thanks AMSOIL!
