Gaining miles per gallon after switching over to AMSOIL 2002 Chevrolet Malibu LS with spoiler.

"I was first introduced to AMSOIL when I had my 2002 Chevrolet Malibu LS. I was told by the dealership that the specifications on the car were 26 miles per hour highway and 23 miles per hour city. After purchasing the Malibu my mechanic informed me about AMSOIL. After the second oil change I noticed a significant increase in miles per gallon (10 mile per gallon increase to be exact). My miles per gallon increased to 36 miles per hour highway and 33 miles per hour city. All that I changed was the oil from standard 5w-30 to the AMSOIL 5w-30 XL. Since then I have bought a 2007 Ford Explorer XLT and have changed the oil, air filter, added AMSOIL’s PI fuel additive and the Coolant Booster and have seen an increase in fuel savings. I have noticed that I am getting the Ford’s measured mph rating of 20 miles per hour highway and 15 miles per hour city after two oil changes. Prior to switching over to AMSOIL products I was only receiving 15 miles per hour highway and 10 miles per hour city.

I will never go to any other type of oil." Frank Mottola
