We provide Amsoil to our customers to help them reduce emissions, increase gas mileage and reduce hazardous waste buy reducing oil use and change out intervals. Amsoil is a pure 100% synthetic oil unlike the others who just play on words. The law states that if an oil has more than 51% synthetic in it you can call it a synthetic oil, the only Amsoil can state it is a 100% pure synthetic oil and thus it does not have all the issue like the others. In fact if used with the special and superior standard Amsoil filters, your oil intervals can be extended up to 15,000 miles or more if used in conjunction with the Amsoil special bypass filer. We can attest to this as the President of Go Green World Product, LLC has used nothing but Amsoil in his truck and he only changes the oil every 30,000 miles. He has gained 2 miles to the gallon and Chevrolet preformed a compression check on his engine as 110,000 miles and could not believe that it has the same compression of an engine with only 40,000 to 50,000 miles on it. This contest to the superiority of this product and why we deal in it exclusively!
