We are proud to offer the Liberator Fuel Saver for Heavy Duty Diesel Truck application. We have spent years researching the effectiveness of the Liberator Fuel Saver in heavy-duty diesel trucks. According to our many on road tests, a typical truck operator can gain a .4 miles per gallon with the Liberator Fuel Saver installed. With the average loaded heavy-duty diesel truck obtaining only 6.0 mpg, a .4 mile gain equals to an incredible savings. That savings equates to thousands of dollars per year per truck! Figure the possible savings like this – if a truck averages 2500 miles per week at 6.0 mpg, the average amount of fuel burnt is 417 gallons bought at $2.75 per gallon, equaling $1147. The same truck averaging 6.4 mpg will only pay $1074 for fuel during the same week. That’s almost $75 per week in savings, or $3900 per year! You can save up to $3900 a year for only $99.95! And, if you have an engine without an EGR unit, you can expect even greater fuel mileage increase and savings.

And, don’t forget, the Liberator Fuel Saver not only reduces your fuel use, it increases low-end torque. Here’s what one over the road truck driver had to say about his experience with the Liberator Fuel Saver – I have been driving a truck for almost 43 years. This device gives it more pulling power, where you can go up the hill and not shift, and makes it a lot better, cause the less you shift, the better fuel mileage you get! – Denis Lee Durant, professional truck driver for Teton Transportation
