    OBJECTIVE:
    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.
    ISSUES:
    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
    (DPF).
    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.
