Update August 2016: Chrysler now requires API 5W-40 motor oil for all model years of Ram 1500 with the EcoDiesel engine

Finally someone is offering a diesel engine option for a modern day half-ton, but we can’t offer an engine oil for it just yet. Here’s why…

If you have a 2014 Dodge Ram 1500 equipped with the brand new “EcoDiesel” 3.0L diesel engine and are looking for AMSOIL synthetic engine oil for your truck, please stand by. At the moment, AMSOIL cannot make a definitive motor oil recommendation for this engine and are performing due diligence to see if any of their current products will meet the Dodge spec or require reformulation.

What we do know so far is that these engines require a synthetic 5W-30 with low volumes of sulphated ash, phosphorous and sulphur (also known as “SAPS”). The required engine oil specifications are “ACEA C-3” (from the European Auto Manufacturers’ Association) and Chrysler “MS-11106”.

Why Can’t Just Any Oil Be Used?

Tip: Do not use just any 5W-30 diesel engine oil in this new RAM 3.0L engine. The reason that a low “SAPS” motor oil is required is because this engine is equipped with very sophisticated emissions components that can be fouled when exposed to high volumes of certain motor oil ingredients. For this reason, it is vital to stick to an oil that meets the aforementioned specifications. Dodge is not trying to make your life complicated by suggesting an engine oil that may not be offered at every parts counter. This engine really does require a motor oil with specific fundamentals.

We have seen this situation for years with many European auto brands, so rest assured that eventually product options will expand. The reason that this engine requires an motor oil that could be considered “Eurocentric” may have something to do with the fact that it is manufactured by VM Motori, an Italian engine maker.
