Proven Fuel Economy with Advanced AMSOIL Motor Oils
Fuel economy is becoming more important with each passing year. Gas and diesel prices keep rising, putting a major strain on businesses that rely on vehicles and heavy equipment in their daily operations. AMSOIL synthetic lubricants improve fuel economy by allowing moving parts to move more freely, using less energy and creating less friction than when conventional lubricants are used.
Testing Fuel Economy Where it Really Matters
The science behind fuel economy with advanced AMSOIL motor oil is simple. Less friction and drag improves fuel economy. This applies for any vehicle or equipment that has an internal combustion engine (Gas or Diesel).
Our customers report significant fuel economy gains as much as 10-15%. To better understand and standardize expected fuel economy gains AMSOIL decided to put it to test using an independent research institute. A month long test were conducted on Class 8 diesel trucks (Semi Trucks).
Semi trucks were chosen for 2 reasons. First reason is that fuel costs effect trucking industry more than any other. Secondly, if AMSOIL benefit Class 8 Trucks to save fuel, it should benefit just about any other engine.
Fuel accounts for roughly 37 percent of Class 8 truck operating expenses, and reducing fuel expenses is a top priority for truck operators.
AMSOIL is the leader in the race to develop fuel efficient low-viscosity lubricants for trucking and other heavy-duty diesel applications. Independent laboratory testing shows AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil in the engine and AMSOIL synthetics in the drivetrain provide up to 8.2 percent more miles-per-gallon than other popular lubricants provide.
For best results, use AMSOIL Synthetic 20W-50 Racing Oil for the transmissions and AMSOIL Synthetic 75W-90 Gear Lube for the drive axles along with AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil for the engine.
