5W-20 Increases Fuel Economy

Ford Motor Company reports that the company’s switch from recommending 5W-30 viscosity motor oil to 5W- 20 viscosity motor oil has saved 700 million gallons of gasoline since 2001. By reducing load and internal friction, lighter viscosity 5W-20 motor oils reportedly increase fuel economy by a half mile per gallon. In addition, Ford reports its use of 5W-20 oils has reduced carbon dioxide emissions by about one million metric tons a year. AMSOIL Synthetic 0W-20 Synthetic Motor Oil (ASM) and XL 5W-20 Synthetic Motor Oil (XLM) deliver outstanding fuel efficiency and superior wear protection over competing synthetic and conventional motor oils.
