Question on 2013 Dodge Ram Oil Change Recommendations
I am wondering what AMSOIL will do to address the new 15,000-mile drain interval suggested with the 2013 Dodge Ram with the 6.7L Cummins engine.
Since the 6.7L engine was introduced in 2007 with the DPF and regeneration system, AMSOIL has dropped the 3X OEM drain interval recommendation on its Premium Synthetic Diesel Oil.
With the new OEM drain interval now set for 15,000 miles on the 2013 model Cummins-equipped trucks using conventional oil, I would think AMSOIL Premium Synthetic Diesel Oil could revert back to the 3X drain interval.
AMSOIL supports the OEM recommended 15,000-mile drain interval in 2013 Dodge Ram applications. Dodge
redesigned the emissions strategy of its 2013 6.7L Cummins engine with the introduction of the selective catalytic
reduction (SCR) system, an improved exhaust gas recirculation (EGR) system with a larger heat exchanger and improved air induction system.
The diesel particulate filter (DPF) and its regeneration strategy, however, have not changed; in-cylinder regeneration pushes fuel on the exhaust stroke. Although the reduced frequency of DPF regeneration may decrease the fuel dilution issue, AMSOIL believes the risk is still there and
does not recommend extended drain intervals beyond 15,000 miles without appropriate oil analysis.
AMSOIL OE Synthetic Diesel Oil presents an excellent lower-cost option in these applications.
AMSOIL recommends Premium Synthetic Diesel Oil (DEO, DME) for extended drain intervals of up to three times the original equipment manufacturer (OEM) recommendation, not to exceed 50,000 miles/600 hours/one year, whichever comes first.
