AMSOIL synthetics and Rex Shobes Oldsmobile are a winning combination. Rex is a Dealer in Kimberly, Idaho. He got into AMSOIL products mainly for his 1976 Oldsmobile drag racer. Rex put AMSOIL Series 2000 20W-50 in his 5-year old 485 horsepower 455 engine prior to a race in 1999. Rexs car ran an elapsed time of 7.62 at 87 mph in the eighth mile and a 12.32 elapsed time at 107 mph on the quarter mile which earned him two wins. After putting AMSOIL in the engine we found an oil pressure gain, Rex said. Elapsed times picked up a little after several runs once the oil got worked in. Rex also uses AMSOIL Series 2000 racing grease in the U-joints and front wheel bearings. "I am still using the parts I had in the car 4 years ago when I started using the grease," Rex said. With the Series 2000 75W/90 Gear Lube, Rex is averaging 2 years per gear set. After seeing what AMSOIL products have done for my race car, Rex said, I am starting to sell more of it and plan on selling the 2000 racing products at each track I go to.
