We have just purchased a new(to us) 2007 Ram 3500 with the 6.7. It has 8000km(5000 miles) on it and I'm wondering if anybody out there has used synthetic oil in a similar motor? Being under warrenty is a concern as the oil has to meet Dodge specs. This truck also has the 6sp auto and has anybody used synthetic oil in the tranny? One other quest, we had a K&N in our older diesel 1-ton and liked that. Any recommendations there?? Looking forward to your recommendations..RMK

I started using synthetic oil at 10,000 miles. I have heard different ideas about when to start, I tow heavy alot!! So I decided to make the switch. I am using Guardol 15w- 40 full synthetic. The only thing that you need to look for is that the oil you choose is API CJ4 and it's low ash...
Good luck. I havent tried synthetic in the trans. But I will be doing the diffs soon.
