I just bought a 2013 dodge ram quad. it can with a lift kit 35" tires. when should I change the break in oil? what oil should I use after the change? thanks

When you change it is personal preference. It doesn't come with 'break-in oil', so you can just go until the EVIC tells you a change is due. That will probably be before 3000 on a new truck, if I recall correctly. Subsequent changes should be around 8000 miles on a 2013. I personally change oil on a new vehicle around 1500-2000 miles.

Use whatever oil is recommended in the manual, in terms of specifications. If you have a Hemi be sure to use the correct weight because the MDS system depends on that. Don't ask about what brand or synthetic vs. non-synthetic here because you'll just get a ton of varying opinions and arguments.

I'd be more concerned about when to change your universal joints.

Gonna be a lot of extra wear on them from that lift kit.

cv axles, ball joints, tie rods, brakes, extra flue, and the axles are still close to stock ride height.

But, it's all in what a person wants, often cool looking leaves my cash frozen.
