Have a new 2007 5.9 Dodge diesel, is it safe to use 2 cycle tw3 oil in the
fuel as a lubricant. I've read it can do damage to some of the new pollution
control systems that were installed on this years model. Worried about the low sulfur fuel use in the truck with a lack of lubricity. Does anyone know if it is safe to use 2 cycle mixture in this newer engine.

 

I run it without any problems in my 06 5.9, not sure if there is anything different between the years.

 

I thought the 5.9 wa spared most of the emission equipment that made its way onto the 6.7?

 

new emission stuff is on new moter, the 6.7
