Maximum Miles Per Gallon
AMSOIL synthetic diesel oils' low coefficient of
friction reduces friction-related energy loss, which increases fuel
economy. In fact, the Environmental Protection Agency's (EPA) Federal
Test Procedure (FTP) confirms a 1.6 percent increase in fuel economy
at a mix of 55/45 city/highway driving when using AMSOIL Premium
5W-40 Synthetic Diesel Oil in place of conventional 15W-40 diesel
oils. Many AMSOIL users report even greater improvements. The result
directly reduces fuel costs.
Extended Drain Intervals*
synthetic diesel oils neutralize acids, resist heat and control soot
longer than conventional oils. Their premium synthetic chemistries
allow motorists to safely extend drain intervals up to three times
longer than OEM recommendations, saving money and time.
Extended-drain savings can mount further when by-pass filtration and
oil analysis are used.
