AMSOIL DOMINATOR Synthetic 2-Cycle Racing Oil Solves Engine Issues

OM DONOHUE HAS SWITCHED TO AMSOIL DOMINATOR Synthetic 2-Cycle Racing Oil and is having impressive results. Donohue races his 2000 Yamaha GP1200R 1200cc, 155 HP personal watercraft. "Out of the box, it would go about 63 mph, not fast enough for Limited Class Racing," said Donohue. "As I began to modify the engine to gain horsepower, I began having reliability issues."

Donahue said he installed a milled head and an aftermarket exhaust system, and soon had a non-running motor. Upon disassembling the engine, Donohue could see the problem appeaared to be too much heat being generated between the pistons and cylinders.

"I decided to switch to pre-mix fuel and spent probably $500 repairing damage to the cylinders." No more than 40 hours later, he had the same problem.

"After rebuilding the engine a second time, I switched to AMSOIL, and that was 80 hours ago," said Donohue. "I pulled the head off the engine, and the cross-hatching on the cylinders is as visible as the day I had them machined." Donohue said that after the change-over, he initially ran AMSOIL Series 2000, but now uses AMSOIL Dominator.

"I have 100 percent confidence in your oil to run a two-to-four hour endurance race, and I know I will have a running motor when it's over," said Donohue.
