Currently having dealer changed oil/filter every 3500mi. I do very little towing and almost all is highway mileage at 75mph. With EGR/DPF deletes and MM installed using it for mileage increase what should I look for in terms of oil/filter change intervals? Thanks.

3500 is pretty early given your usage, you can extend that out to at least 5000 probably more, I run about the same as you and change every 5000-6000 miles, I'm sure i could go more since the factory interval is 7500 with the emissions crap on there.

Hounddog,

I :agree2: the extended oil change should be higher.
In fact I do it at 10,000 because of the full synthetic oil I use !:thumbsup:
They say 7500 with dino oil, so better oil longer interval. Just like I did with my 18 wheeler------

My oil was black as coal before I did the deletes to my 6.7. It was still black for a few oil changes but it was staying visibly cleaner. Now the oil actually stays fairly clean between changes! I am changing it now every 10,000kms or 6000 miles. After testing the used oil I found that I could go longer but I probably will stick with changing it every 10,000 kms as it is easy to know when it is due with a quick check of the odometer. I am sure the engine oil could go 20,000 kms per change...especially if I added an oil by pass system. I know of many guys who run 20,000 mile oil changes (all highway and towing) in their 5.9s and 6.7s and do not run a by pass system and their trucks do not seem to suffer for it.

I have seen the inside of engines and the oil pickup tube getting restricted because of extended oil change intervals. Factory says maximum change interval of 7500 miles. The engine is serious money if it blows, and if it's sludged up you pay. We suggest 5,000 mile intervals or when the oil life monitor tells you whichever comes first, regardless of conventional 15w40 or synthetic 5w40. My baby gets new Rotella 5w40 synthetic every 5,000 miles along with BG MOA.

What other routine maintenance do the 6.7's require?
MAINTENANCE SCHEDULES - DIESEL


Oil Change Indicator System


Ram Truck Pick-Up (2500 and 3500 Models)
The vehicle is equipped with an engine oil change indicator system. This system will alert you when it is time to change the engine oil by displaying the words “Oil Change Required” on the Electronic Vehicle Information Center (EVIC). The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate depending on the personal driving style. Driving styles such as frequent stop and go type driving or extended idle time can increase the frequency of the engine oil change. This is the result of more frequent regeneration of the exhaust after treatment system, which can decrease the life of the engine oil. Failure to change the engine oil per the maintenance schedule can result in internal engine damage.

For information on resetting the Oil Change Indicator message, refer to “Oil Change Required – If Equipped,” under “System Status (EVIC Displays)” in the “Electronic Vehicle Information Center (EVIC)” Section of this manual.

When prompted by the Engine Oil Indicator System, the engine oil and filter must be changed. If not prompted by the Engine Oil Indicator System within 7,500 miles (12 000 km) or six months since the last oil and filter change, replace the engine oil and engine oil filter. Under no circumstances should oil change intervals exceed 7,500 miles (12 000 km) or six months, whichever comes first.



Ram Truck Chassis Cab (3500, 4500, and 5500 Models)
Replace the engine oil and oil filter every 7,500 miles (12 000 km) or six months, or sooner if prompted by the oil change indicator system (if equipped). Under no circumstances should oil change intervals exceed 7,500 miles (12 000 km) or six months, whichever comes first.



Perform Service Indicator
The vehicle will require emissions maintenance at a set interval. To help remind you when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will display “Perform Service”. When the “Perform Service” message is displayed on the EVIC it is necessary to have the emissions maintenance performed. Emissions maintenance may include replacing the Closed Crankcase Ventilation (CCV) filter element, cleaning of the EGR Cooler, cleaning of the EGR Valve, and/or cleaning of the turbocharger. The procedure for clearing and resetting the "Perform Service" indicator message is located in the appropriate Service Information.



Oil Change Indicator - Reset
The vehicle is equipped with an engine oil change indicator system. The “Oil Change Required” message flashes in the EVIC display for approximately ten seconds after a single chime has sounded, to indicate the next scheduled oil change interval. The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate depending upon personal driving style.

Unless reset, this message continues to display each time you turn the ignition switch to the ON/RUN position. To turn off the message temporarily, press and release the Menu button. To reset the oil change indicator system (after performing the scheduled maintenance) perform the following procedure:

Turn the ignition switch to the “ON” position. Do not start the engine.
Fully press the accelerator pedal slowly three times within ten seconds.
Turn the ignition switch to the “LOCK” position.


NOTE: If the indicator message illuminates when you start the vehicle, the oil change indicator system did not reset. If necessary, repeat this procedure.

At Each Stop for Fuel
Check the engine oil level about 30 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the accuracy of the oil level reading. Add oil only when the level is at or below the ADD or MIN mark.
Once a Month
Inspect the batteries, and clean and tighten the terminals as required.
Check the fluid levels of the coolant reservoir, brake master cylinder, and transmission and transfer case (if equipped), add as needed.
At Each Oil Change
Change the engine oil filter.
Inspect the exhaust system.
Check the automatic transmission fluid level.
Check the manual transmission fluid level.
Check the coolant level, hoses, and clamps.
Lubricate outer tie rod ends.
CAUTION: Failure to perform the required maintenance items may result in damage to the vehicle.
Proper operation of four-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Tire rotation schedule should be followed to balance tire wear.

DenverDodgeDealer,

Good reply if the guy didn't have a book.
BUT I think he is talking about synthetic oil changes.

I use Rotella Triple T along with 2 quarts of Lucas oil additive, and change at 7000 or oil change required light on EVIC. So far the light comes on shortly after my 7000 mile change. I can get the oil on sale or at Sam's club and buy my filters six at a time from Geno's. I use the Lucas to be sure I have good film coverage in the engineand to keep everything nice and clean. I got hooked on additives in 1964 when my brother was using STP and I was not in identical cars. When we each had over 25000 miles we took off the valve covers. His was as clean as a new engine. Mine had some black sludge starting to form. So I have used additives ever since. Total cost for an oil change which I do myself is about $60. Not even worth considering extending the interval. I have never used any synthetic oils. I guess if one does oil analysis etc. then the intervals could be extended. But to what end? Certainly not saving any money. And the risk of acid or other buildup is too great.

If you do your own maintenance keep all your records and reciepts showing the dates and mileage and vin. number. The manufacturer's are really cracking down on seeing maintenance records. If a vehicle comes in looking pristine inside and out with a failure you'll have an easier go, but if it looks like, well you've all seen them and you dont have any maintenance records and the engine is sluged up and fuel filter bowl is full of rust and debris, we all loose, yes even us dealers. That being said if you keep it clean and maintain it you wont have a problem in the first place. We see customers with hundreds of thousands of miles with no problems, and yet we also see failures, but usually to vehicles that look like you would expect to see a failure. I am not trying to pour salt on any wounds just letting you all know if you take care of your own truck and you have a failure you will be asked to provide acurate maintenance records.

some of the owners manual stuff is generic, and the people who write the manual dont service the vehicles. If there is no grease fitting you cant grease it. That being said I have heard of some vehicles with a very small hole in the rubber boots for allowing moisture to dry out from condension, some people try pushing a small grease gun needle in there and applying a small amount grease, however some people cause more harm than good. Personally if it is a sealed unit it shouldnt need grease. The factory calls them lifetime units. Not sure who's lifetime though.

Gene,

I like all the grease fittings on my 96.
My 08 has one small fitting that is hard to get at. Why didn't they make that one a lifetime u-joint?
