More MPG with AMSOIL! Less Friction, Better Fuel Economy

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.

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.

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.

At the request of AMSOIL INC., an independent research institute conducted a month-long test comparing the fuel consumption of Class 8 diesel trucks equipped with AMSOIL synthetic lubricants to Class 8 diesel trucks equipped with conventional lubricants.

The research institute used the SAE J1321 Joint TMC/SAE Fuel Consumption Test Procedure-Type II, an industry standard test procedure for comparing in-service fuel consumption of a vehicle operated under two conditions, one with the control lubricants in place, the other with the test lubricants in place.

The control lubricants were Shell Rotella T 15W-40 for the engines, Quaker State SAE 90 for the transmissions and Citco 85W-140 for the drive axles. The control truck used the control lubricants for all driving segments and the test trucks used the control lubricants for their baseline segments.

The test lubricants were AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil for the engines, AMSOIL Series 2000 Synthetic 20W-50 Racing Oil for the transmissions and AMSOIL Series 2000 Synthetic 75W-90 Gear Lube for the drive axles. The test vehicles used the test lubricants for their test segments.

All vehicles used Exxon No. 2 diesel fuel dispensed from the same storage tank for all driving segments.

Each test vehicle ran a baseline segment, in which the truck was equipped with the control lubricants, and three test segments, in which it was equipped with test lubricants. The control vehicle concurrently ran each driving segment using control lubricants.

Conditions including speed, tire pressure, headlight and fan use and window openings were held constant between all vehicles in each driving segment. Finally, testing proceeded only if wind direction, wind speed and temperature were within test parameters.

The results showed that the vehicles equipped with AMSOIL synthetic lubricants in the engines, transmissions and drive axles demonstrated up to an 8.2 percent increase in miles per gallon (mpg) over the mpg obtained by the vehicles equipped with the control lubricants.
