I've got a new truck & am wondering at what miles I should do the first oil change. Salesman said 8K which seems way too high to me. I was thinking 1k or 1.5K on the first change, but I'm wondering if Dodge uses break in oil on their new trucks. Also was thinking of putting synthetic in but someone told me the 5.7 Hemi's should not use synthetic oil. Any guidance would be greatly appreciated.
Whoever told you not to run full syn in Hemis is full of s***. Including the first change from factory oil, I have gone 6000-7000 miles per change, and I switched to full syn on the first change.
