Hi,
I have mentioned this topic before, but I need a bit more detail. First, I have a 2004 Ram 2500, Cummins 305/555, auto, 4wd, etc ...
I got 6 years of free oil changes from the dealer. My plan was to use this service until I hit 15000 and then I was going to start changing my own oil with Premium Blue synthetic (Cummins suggestion).
The oil the dealership uses is Mopar 15w-40. I'm assuming this is probably Rotella ... ? Anyone know for sure?
Regardless, this is a 10 year truck and I want to use the best fluids in it. Is it worth, in your opinions, using the synthetic rather than letting the dealership change my oil for free?
Let the flaming begin ...
Thanks Craig C.
