AMSOIL Won’t Let Two-Million Mile Trucker Retire

One of the highlights of working at AMSOIL is hearing stories from people about the extraordinary performance of AMSOIL products  – people like Jerry Pruett.

In October 2012, we brought you the story of his one-million-mile-plus Kenworth. The Woodhull, Ill., native installed AMSOIL synthetic lubricants when he bought the truck new in 1999. After reaching 1.6 million miles on the original transmission and differentials and 1.1 million miles on the factory-rebuilt engine in 2012, Pruett has since eclipsed 2 million miles and shows no signs of slowing down.

The truck, which Pruett uses to haul freight predominantly around the Midwest, has required little maintenance since 2012. In November of that year, Pruett did finally need to replace the fuel injectors. “The spray pattern on the pistons was still good,” he said. “The springs must have weakened over time. Other than that, there was nothing wrong with them.” All six injectors lasted 1.1 million miles, which Pruett attributes to continuous use of AMSOIL Diesel Injector Clean.

Since he was replacing the head gasket anyway, Pruett elected to replace the entire cylinder head to expedite replacement of the injector cups. Other than the head and a new water pump, the engine has required no work in the intervening years. “It keeps humming along,” Pruett said. The turbocharger is still original. Pruett runs AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Oil. He also uses an AMSOIL DUAL-GARD® Oil Filtration System and changes oil approximately every 100,000 miles, which saves him significant money. And, the differentials and transmission are still original after 2 million miles.

The people with whom he shares his story still have a tough time believing it. “They shake their heads in disbelief,” Pruett said. “They think, ‘No way can you have that many miles on a truck.’ And I only change oil once a year.”

Now 64 years old, Pruett doubts he’ll be working long enough to see 3 million miles. He hopes to spend more time pursuing his AMSOIL Dealership – and he has a great testimonial for everyone he meets along the way.

“I’m not only an AMSOIL Dealer, I’m an AMSOIL user and abuser,” Pruett said. “I won’t use anything else.”
