    Communicate the discovery and cause of excessive fuel
    dilution in 2007–2010 light-duty diesel pickups from Ford,
    GM and Dodge and the resultant reduction in the drain
    interval recommendation for AMSOIL Premium Diesel Oils
    in these applications.
    AMSOIL has documented increasing levels of diesel fuel
    contamination (fuel dilution) in the engine oil in 2007–
    2008 light-duty diesel pickups from all major vehicle
    manufacturers, and indications are that 2009 - 2010
    models are affected as well.
    Research indicates that fuel dilution is intensifying due to
    the use of in-cylinder post-fuel injection during the engine’s
    exhaust stroke to regenerate the diesel particulate fi lter
    Fuel in the oil reduces the oil’s life expectancy and
    effectiveness. Because diesel fuel is a natural solvent, fuel
    dilution in motor oil causes a decrease in viscosity which
    may lead to an increase in engine wear rates.
