6.7L Cummins Forum

Hello I just purchased my second dodge product and went with a Ram 2500 ST with the 6.7 Cummins, and the ram-box option. I have questions I'm hoping someone can help with, first it did not come with a key fob for remote entry to unlock the doors suggestions for an aftermarket? 2. Do I need to put additive into the ultra low sulfur diesel fuel to boost the cetain? 3. I live in Cincinnati its cold not ultra cold do I need to put an additive to the diesel fuel to keep it from jelling? 4. Suggestions on a tonneau cover or bed liner. 5. Tips on the break in of the engine it has 210 miles on it now after driving back from Lexington?
Any other suggestions would be greatly appreciated, I plan on keeping it stock till the warranty and extended warranty run out. Thanks, Mike.

Howdy mike!

Congrats on the new truck. Can't help with the first question about the locks.

I live in Kansas with lows below 0º and I've not had any problems in 5 winters.

As for break-in just don't idle around and you'll be fine

Sorry to rehash your whole thing, but I have severe CRS these days. Great choice, BTW; looking to trade up to a 12' 3500 CCLB ST in a few months.

1. Unless they want a fortune I would go with OEM on that. With all the electronics now I would feel better knowing it was designed for my truck without electrical issues. Plus, it breaks (or the dealer screws up) it's covered.
2. Maybe I'm wrong but I don't know of anything that can really bump up the cetane that much to justify the cost. Since these engines were designed to run on ULSD I don't know if just adding something will have any affect. Maybe someone more knowledgeable can chime in?
3.Not needed but, for piece of mind, I use PDS anyway; living in FL we don't worry about freezing too much. H2O in the fuel, however, is a big concern for me. Plus, it just makes me feel better for doing it.
4a. Bed liner: DualLiner Truck Bed LinerBest dent resistance and most versatile liner; plus it's under $400 shipped. I'm getting one because I'm using a B&W Turnball with Companion hitch, which won't allow for a thick bed mat. I can take the mat out at keep the sides in place by some other means while towing.
4b. Tonau: BakFlip Tonneau Cover - BAKFlip Tonneau Covers I'm looking at the G2; versatile, locks, all metal and cheaper than a Roll-N-Lock M series.
5. 2nd Squids resonse. Just baby it for 500 miles and you should be fine.

One side note; BMW used to recommend a 1200 mile break-in service that changed all the fluids. There is a document I have called "Lifetime Maintenace Schedule" that I can email you if you PM me. While it may be geared towards BMW's, there are some really good maintenance tips in there that pertain to any vehicle.

Good luck and enjoy your new rig!

I went with RBP fuel additive. Just google Rollling big power diesel fuel additive it will come up. It does a few things for you. while I do live in mild climate it does get down to freezing from time to time. I have read and talk to a few people and they recommend the RBP, a few others also said that Stanadyne is another good one. The one thing I like about RBP is 1oz treats 32 gallons and you get a bottle that treats 500 gallons for around $25. You want a little something in your fuel to lube your injecters, plus diesels love detergents lol. here is a link to check out http://www.carid.com/miscellaneous/r...FQF3hwodM0BH5w

Congrats. I just bought my first diesel and dodge in October. Owners manual says more load the better for the break in. So I pulled everything I had and drove it hard when not having a trailer. Use the exhaust break everyday except when slippery. My brother-in-law told me he has never added any additive in the last three dodges he has had. He never had a problem when it was below zero so much last year. Just keeps it plugged in at night. Plus your fuel is already treated at the pump where the weather gets cold. It is here in Iowa any way. I haven't had any fuel problems or hard time starting either this winter. I do plug it in when It gets in the teens. Hope that helps.
I put a tonnue cover on mine plus I'm going to get the spray in bedliner from Linex.

Be careful with the purchase of a DualLiner for these 2010 to 2012 year trucks. I bought one for my 2011 Ram. While the in bed components are fine and fit nicely the tailgate piece is nothing but trouble. It does not fit right. There is a large gap at the top of it between it and the tailgate itself. Things snag on it and debris and dirt collect there. I complained to DualLiner and found out their customer support is lacking. They are slow to respond. First they said they had a problem with their CNC machine, then they said there were no problems, then they said there is nothing they can do. After 3 months they refunded me $50.00 towards the purchase of another tailgate protector. I found out from other forums people have been having the same problem since 2010 when the tailgates were redesigned. The contour of their tailgate piece doesn't match the contour of our tailgates thus leaving the gap. If I knew then what I know now I would not of purchased one. Way too much hassle with them. I can provide pictures of what I am talking about if needed. Also the link to the other forum...

I was chatting with the fellow at the parts counter about additives, he's heard of some issue with the ones geared at reducing H2O, apperantly the stock filter is not up to the task of catching the now tiny particles of water. Allowing them into the injectors/engine.

Upgrading to something like a raycor(spelling) filter will help, but I heard dodge may give grief with warranty running a different fuel filter.

Gas is the cheapest anti gel just don't go overboard, half a gallon to a tank is plenty at any temp. Used it for years never had a problem in trucks or pickups. I've seen howes gel in the sleeper.
