2013 Ram truck

The 13's can put fuel into the exhaust still, so fuel dilution can happen. However what Cummins did was that they tuned the motor to produce less particulate matter in the first place. So DPF plugging is a slower process on a new motor and all NOx treatment is handled downstream (EGR is only used to reduce PM production, no longer needed for NOx control). So the newer trucks are intended to regen mostly in a passive manner. As long as you get a few good long trips in every month or so and keep the short-trips to a minimum, you should rarely notice an active regen. I've only witnessed 3 active regenerations in the 3,000 miles I've owned it. My fuel mileage still remains fairly high as well.

My 12 has had less than 1% fuel dilution each time I have had Blackstone test the oil. I do drive it like it was intended to be driven. No short trips along with towing. Oil changes have been near 7,500 miles this last time just over 6K but no towing.

The 13's and newer will not fuel dilution problems at all since the exhaust treatment is down stream of the engine.

Thanks guys for keeping me straight. I went back and checked again and I made a mistake it was a MY 2012. That makes me feel better.

You might try going over to the Cumminsforum for better information. I haven't heard of any 2013 DEF engines with fuel dilution. Actually the Ram ad's suggest they will go 15k miles between oil changes.

I'm thinking about getting a new leftover 2013 Ram 3500 DRW 6.7 but I was reading on the TDR about some of the trucks having short oil change intervals. One poster had to change oil 4 times in 10,000 miles because of 5% fuel dilution and the truck told him that he needed to change.

Is anybody with a 13 having this problem or have you heard of anybody that has and how wide spread is it? I sure don't want to get a new truck that needs and oil change that often.

Also what kind of mileage are you folks seeing on the trucks, empty and loaded?

Thanks

You sure that was not with an earlier 6.7? I would not want a non DEF 6.7, 2007.5-2012! For that and poor mileage. Regen used all 6 injectors to clean exhaust trap to often, dumping lots of fuel in the cylinders.
