Additives aren't necessary at all. The Ram has good filtration. In the winter you might want to add some anti-gel if you get super cold temps, but nothing else is needed. Ram specifically states that additional additives are not recommended.

Fuel filters are actually a mileage based change, not a time. Every 15K miles they need to be changed. There is a Ram dealer from down south that sells OEM fuel filters for about $100 (as of last year). Its easy enough to change yourself. I buy the filters and invest about 30-45 minutes of time and save $400.

Oil and filters... my truck is essentially used for towing only so I put about 8k miles a year on it. I change my oil once a year, not every 6 months. Some will yell at me, I'm okay with it. I tow 10K lbs and I'm not pushing my truck with weight, speed or heat. I'll probably get an oil analysis done right before my next change just to confirm that everything is still doing fine. The filter is accessible from the right front wheel well, behind the plastic shield. It can be a little annoying to get to, especially because the recommend pre-filling the filter before installing.

Exhaust brake. I use it every single trip. Actually, I turn on tow/haul and exhaust brake every trip. T/H saves the truck from lugging the engine in town. EB saves on the service brakes. T/H and EB makes the braking more aggressive. If you plan ahead a little, you can use the EB to slow you from highway speeds to 20 mph, then service brakes the rest of the way. Towing in the hills/mountains... EB is AMAZING! An occasional gentle tap (literally a 1 second tap) of the service brakes will downshift the truck and engage more aggressive EB feature when going downhill. I love it. I don't need the diesel for my current trailer and don't ever expect to tow massive heavy trailers... but that EB and ease of doing downhill will likely keep me in a diesel for life.

9 mpg towing a large heavy 5th wheel. Sounds accurate. I get about 12ish towing a 10K lbs travel trailer.
Around town I'm closer to 16-17 and on the highway I can get 20 to 21, not towing of course.

That's better mileage towing and around town than in my gas half ton before this.

2016 Ram 2500 Mega Cab 4x4 with the CTD and only 50K miles. Picking it up this afternoon. My previous diesel experience was an '05 F250 with the 6.0. With that, there were all kinds of additives .....I'm seeing oil changes every 6mo or 15K miles and fuel filter once a year. Is this good? Synthetic?

Should I always use the exhaust brake or only when towing or only when towing grades?


No fuel additives needed. For DEF I've always run Peak Blue DEF either in the 2.5 gallon containers or I've used the fill nozzle at truck stops. The one time I used cheap DEF I got sensor issues for insufficient catalyst. After I drained that junk and refilled with Peak I've never had that warning again.

Oil should be Rotella T6 5W40, or any other favorite synthetic 5W40 diesel engine oil. The book says you can run 15W40 down to 0*F, or you can run 5W40 synthetic at any temp range. Change interval I use is 1 year or 10,000 miles. I use Fleetguard LF16035 filters.

Fuel filters are good for 15,000 miles and I've not seen any age/time limit on those. I used to always change oil and fuel filters at the same time until this year when I realized I only put 5,000 miles on the truck since the last change. Online you can find the combo of both fuel filters for about $90. But I figured if the filters are good for 15,000 miles there's no need to spend that money so I'll run them until I hit the mileage limit.

I usually drive with the exhaust brake onall the time. When towing anything I also switch on the Tow/Haul mode. This steps up the exhaust brake when decelerating or going down a grade and greatly reduces the amount you need to use your brake pedal.

I tend to fall in the DEF is DEF camp. I've run the cheap Walmart stuff, the even cheaper pump stuff and the Peak Blue stuff. Recently I've been mostly running Peak Blue because I can get it at Costco for $10 and it's the most convenient option for me since I'm there every week. Walmart or going to the closest DEF pump requires a special trip out of my way and it isn't worth the time to save literally a few bucks a year.

I've got a 17 with close to 100k on it. Never added any additives, just fuel. My exhaust brake is always on and I use T/H when I pull the trailer. I had a 6icko too, and like someone else said, it was a temperamental piece of junk. I order all my filters on Amazon and change them at about 10k. Maybe because of the Ford, but I only use Mopar filters. I also ordered a fuel cap from there since I have a flatbed on it now and didn't want the neck open. Towing 10k, I get about 9-10mpg's and unloaded, I average around 18.5.

Buy filters on Amazon. 40$. DYI in about 1/2 hour. Only a fool pays dealer prices.


FYI $40 filters for 4th Gens are **** filters.

OP, nice choice!
50k and 4+ years old.
1. Change oil by mileage unless you can verify that it's been changed at 6 months previously. Reason, 6mo intervals are totally unnecessary in and of themselves , save for possible warranty coverage issues from not "following" the recommendation. You'll be out of warranty soon anyway, if not already based on the 5 year mark.
Save your money for useful maintenance.
2. No "additives" needed for anything. Fuel and DEF are the only 2 things you need to put in the tanks.
3. With that mileage and age, I'd service the trans, complete fluid exchange, diffs and transfer case and start thinking bout coolant/brake fluid and hydro boost fluid change in the next year.
4. Fuel filters, easy to DIY. Make sure you're buying the right quality/micron rating and not knock off filters.
5. That is all. Enjoy!

that high price was DEALER Service

9 mpg is towing a heavy high profile 5vr at 70MPH

Nothing out of the ordinary



OP.....
No additives required
Oil/fuel filter changes routinely.....clean oil/clean fuel and engine will last LONG Time

Exhaust Brake......that is a Variable Geometry Turbocharger (VGT)
It uses a sliding nozzle ring that varies the power from turbo and amount of air delivered to engine
TURN IT ON and always run with it ON so it doesn't bindup and you end up having to get a 'cleaning service' preformed


Is it time for your medication or mine?
