oil change required 6.7

[JAKE 2544]

I read through the posts about the oil change required light on the 6. 7,many say that the dealer says to change the oil but what is every doing when it comes on at 1200 miles. I took delivery of my special order truck in july and dont know if the latest flash has been done. No problems so far but at 1200 miles on a diesel is absolutely insane.

My driving is mostly city with no idling or minimal. I reset the light and plan on changing it at 5000. Theres no way i'm changing my oil every 1200 miles. What is everyone else doing?

HOW HARD ARE YOU DRIVING IT Mine did not come on until 5000 mi just turn on egintion and press gass pedle 3 times should be fine

 

[captaindean]

sorry what was your build date

I changed mine the first time at about 3000 miles(nothing on the overhead) then the overhead came on about 6500 miles later so I changed it again. I'm at about 13,500 now and nothing on the over head yet. Have thinking of doing an oil analysis just out of curiosity. Got my jug from Blackstone the other day.

I as well changed the oil the first time at just over 3,000 miles and just this week the oil change required light came on at 7,440 miles. I have done very little towing and don't sit idling for long periods of time so I am probably going to reset the reminder and go the recommended 7,500 before changing it again. I believe this is the first time the light has come on. If this light comes on based on mileage only (I have read differently on here) at 7,500 mile intervals it's useless in my opinion.

A lot more soot in these enviroment freindly motors so we should probably follow the change interval or more

Oil Change

Changed mine at 980 miles the first time, then went on a cross country vacation with the trailer. changed it again at 4560 mi. on the east coast. The light came on at 7500 miles. I just reset it and changed it again when I got home at 9100 miles. normaly change about every 3500 or so , oil is cheap and our engines are not. towed about 9500 pounds the whole way and got 9. 97 miles per gal at mostly 60-65mph. not as good as the 96, but twice the horse power and tourqe . why complain. Life is short enjoy.

Since it is a new truck i have been very easy on it. Mostly city driving and short trips. I ordered the truck in april and took delivery at the end of july when it arrived off the train.

 

[Caveman]

I changed mine at 5000 the first time. I towed a 10,000 pound RV from Texas to Florida and on the way back at 7600 miles the overhead came on. I reset it and just changed it at 9500.

You will find with oil analysis the EVIC recommendation of an oil change is correct. The Excessive Soot contamination of the oil along with the new CJ-4 Warranty approved oil the oil change interval on the 6. 7 is a nominal 3000 miles or 5000 Km. Not following the oil change indication will be recorded by the ECM and thus you are risking your warranty, however, if this is of little concern then why post the comment!

 

[klenger]

How does the ECM know if you actually changed the oil or simply reset the overhead?

 

[courierdog]

Challenge it and your warranty and find out.
I am not trying to be smart. Just the facts.
I was and Engineer for 42 years and now for a pass time I drive courier / hot shot with my 6. 7.
It is a great truck, however, it does have its share of initial software and sensor glitches.
The ECM/PCM is an extremely powerful and is monitoring much more than is being released or discussed.

So I got my oil changed a few days ago at the dealer for the first time with 5500 miles and no oil light and the next day after 150 miles the change oil light came on... ... Yeah the truck knows when it needs the oil changed. I turned the key on and hit the "diesel" peddle 3 times and the oil change light went away. If it really needed changed wouldn't it go on again?? I have put on 400 more miles since then and all clear...

This 'Oil Change Required' light is a lot like the mystery of the 'Regeneration' no one seem to really know, except Dodge engineering (I hope), why and when these things are supposed to happen. Does anyone have the factory service manual... does it have any trouble shooting or systems logic that explains any of this?



This is only a guess but I think the 'Oil Change Required' light could be based on how the truck is used by monitoring the engine load, shift points, tow/haul switch etc... but I don't see how it would know when you changed the oil unless we do the 3 full throttle pedal pushes. Again guessing here but I would think that maybe each time the oil is changed that we need to reset the system (change oil light or not) by pushing the throttle down three times that way it starts over with it's calculations?

 

[2Rowdy]

I agree with TKeeler. I had my oil changed the second time at the dealer and they did not reset it at all. That is also what I did the first time pushed the throttle down three times with nothing on the overhead.

 

[hatchy]

Maybe the dealer just presses the throttle 3 times and charged you $100 for the pleasure.

 

[JAKE 2544]

Yea,this oil change thing is a joke,it must be sponsored by Jiffy Lube. I hardly think that the computer can actually tell if we changed our oil or not before resetting the light.

 

[sag2]

The oil change light on the CTD is not like the Sprinter or Crossfire systems that monitor oil level and oil condition with a sensor. It instead uses an algorithm just like the regeneration to determine change interval based on time, temp, load, idle, number of regenerations etc. The only way to prove it is correct is to run a couple of samples of oil when the light turns on. I would be willing to have some samples tested if you’re in the bay area or Sacramento area. It would be worth the $27 to find out if the Cummins engineers are close with the calculations. Send me a PM and I'll see if we can put it together.

My dealer pays for all oil changes for the life of the truck as long as I own it and I pay for all other scheduled maintenance with the dealer. They will not change the oil before scheduled intervals, even before my trip to Kansas, I paid the local dealer in Kansas to change the oil for its first change at 2500K because I think the break in period has particles from the new engine breakin. That maybe a myth but as said before "oil is cheap", I dont know if the dealer will change the oil for free if light comes on early or before scheduled miles. How do you have your oil analyzed & where do you get the kit? I would be interested in finding out if this light is accurate that I have never seen yet, at 10K so far. Truck has had an oil change at 2500K and 7800K and have never seen the light. I just checked my owners manual and there is no change oil light that I saw and the interval is at 7500K, and that my dealer has as well , maybe there is no light on the C&C.



I had that on an 05 D/A LLY service truck my company gave me to drive and I thought it was worthless anyway. They even had no schedule in the manual for intervals, they wanted you to rely on the idiot light.

My service advisor suggested I do the 3 pumps on the throttle after my "Oil Change Required" light came on after only 1500 since changing. He explained that most service technicians either don't know how to reset or forget to when you change your oil before the light is triggered. He further suggested that after resetting, if I really do need to change the oil, the sensors will detect and triggered the light within 2 days of normal driving.
