Travis McGhee, of Newberry, S.C., credits AMSOIL products for good fuel economy in all the vehicles he drives.
He started driving a 2008 Chevrolet* Kodiak* C4500 with a 6.6 Duramax* diesel engine in 2009. The truck had about 500 miles (800 km) on the odometer, and a conventional CJ-4 diesel oil was installed in the truck.
“Since day one, the truck had horrible fuel economy of eight miles per gallon,” McGhee said. “It caused the diesel particulate filter to regenerate frequently, about every 100 miles (160 km). The frequent regeneration diluted the oil with fuel and decreased fuel economy.”
The oil life monitor recommended an oil change every 1,800 to 3,000 miles (2,900 to 4,800 km). “This was more frequent than I thought an engine with an oil capacity of 15 quarts needed,” McGhee said. “I knew something was not right, but I didn’t know what. I hated this truck. It seemed like every time I turned around it needed a fuel fill, an oil change or some sort of maintenance.”
AMSOIL Products Increase Fuel Mileage
In 2013, McGhee started modifying his 2006 Pontiac* GTO.* “I was in the market for a high-performance oil at a reasonable price,” McGhee said. His research led him to AMSOIL products, and he became a Preferred Customer.
In April 2014, McGhee’s work truck was due for its 100,000-mile service (161,000 km). “Since I was a P.C., I decided I would change all of the truck’s fluids to AMSOIL products, including the engine, transmission, power steering and the front and rear differentials,” McGhee said. “I immediately started getting 9.5 miles per gallon. I was very impressed.”
AMSOIL technical information showed McGhee that a cleaner tune-up of the truck could mean even greater fuel economy and extend his oil change intervals. “I had my truck custom tuned in July 2014,” he said. “Fuel economy went to 12 mpg and regeneration frequencies went to 300 miles (380 km).” He also started using AMSOIL Diesel Injector Clean and Diesel Cetane Boost. “Now I am at 13 mpg and regeneration frequencies are at more than 400 miles (640 km) and getting better,” McGhee said.
He has logged 5,000 miles (8,000 km) without the oil life monitor light coming on. “I now enjoy my work truck and love to drive it,” McGhee said. “Not only has the fuel economy gone up, but it also has much more power.”
Denali* Improves MPG With AMSOIL Motor Oil
McGhee recently purchased a 2012 GMC* Denali* that had the GM oil from the dealer installed. “I was getting an average highway fuel economy of 18.55 mpg. I switched to AMSOIL Signature Series 5W-30 and went to an average highway fuel economy of 19.65 mpg.”
