I am the proud owner of a 2013 Dodge 1500 with the V6 Penstar and the 8 speed automatic. I just passed over 10,000 miles on it and every day I am more sold on it! If you don't put your foot in it the mileage is amazing it has plenty of power to pass with it and I have towed it on a 1000 mile trip using the tow mode and a 5000lb load again amazing I am very sold. NO PROBLEMS!!
My problem is I am a diesel guy. I have had everything from a 240 D mercedes benz - the 03 Dodge Cummins 5.9 and many others in-between I put 100,000 miles on my last 2003 Dodge 5.9 it and again an amazing truck and zero problems most importantly. I really wanted the Ram Eco but I was just coming out of a horrible experience with a Ford 6.0 diesel and literally found a sucker in my opinion to take it off my hands..cheap and I still wanted to kiss em. If I heard the word EGR valve one more time I might have had it crushed. So here i am no vehicle and need a truck Ford obviously was out of the question. What I have been hearing with the new Dodge Cummins 6.7 hasn't been great... and i really do not tow much more than 6,000lbs about 2x's a year. I live and play in Mexico but the EcoDiesel was not available yet so I went with the Penstar...What about the Dodge EcoDiesel V6 and it needing the ultra low sulfur?? My 5.9 I ran the **** out of it in Mexico with no issues and we have only low sulfur not "ULTRA LOW SULFUR" fuel south of the border. I do make enough trips to make it worth my while to go back to diesel and I can sell for a small loss my truck but I don't want to have issue's with loosing my warranty if I burn up an engine because the fuel they detect does not have enough sulfur. Your the experts I am pulled over what to you think???

Welcome to the forum, glad to have a long time diesel vehicle owner on here. With me being new to diesels I just might have to ask you some questions about them when the time comes

hi Maddog, and Welcome.

My understanding is that the sulfur reduces the time between regeneration of the NOx & DPF filters. The sulfur also increases the amount of the particulate matter going into the DPF. I have also read in the distant past that the sulfur reduces the life span of the DPF...however, it is not detrimental to the system if you fill your tank with LSD vs ULSD every now and then. Think of it this way, it just takes a little more regneration time to clean out and thus your mileage may reduce slightly.

The problems with the first generation of the 6.7 was with the turbo getting stuck with the infamous P2262 code. The 4th injection during exhaust stroke would mix with the soot and you got wet soot going thru the turbo, egr cooler and NOx filter. This added injection also ended up in the engine oil, and thus we needed the oil and filter changed at 3000 miles. The SCR/DEF system almost eliminates the 4 injection except for the DPF regeneration, at which time the egr valve is closed so it does not go thru and clog you egr cooler. I wish they would have done the SCR route from the beginning on the 6.7's, as I would have probably kept my DPF instead of deleting it.

I may go a year without being able to run anything but LSD because I don't have ULSD in my area. I was thinking because that new Dodge V6 is made in Italy it may not have the same requirements for ULSD.

I like the HP version a little better modest 5% increase in torque.

I would suggest to do a some research and see if you are comfortable with going for a year without ULSD.

FWIW, the 07.5/08 Ram chassis cab were allowed to use LSD (500ppm). From what I have read LSD will lead to slightly longer Regen cycles to break down SO2/SO3 down to ash. I could not located any long term negative affects to the SCR/DPF filters. So you end up using a tad more fuel during a regeneration cycle. But again it really needs to be researched.
