I had my oil changed and they added 13 quarts which I thought was right. I assumed they checked after they filled it up. Now I see the book says 12 quarts and it looks to be overfull.

I have driven about 250 miles at about 80-85 MPH. I have not noticed any oil pressure problems or performance problems but the book scares the crap out of you with the aeration and engine damage warning.

I will take it tomorrow and get this rectified but I am wondering if you think I have done any damage. I put in Delo and I dont know what aeration may have taken place of how that may have harmed the engine. I only have 1000 miles on the engine and am concerned about having this happen during beakin.

What do the experienced members of this forum think?

 

You will be fine. One quart overfill won't be a problem. We slightly overfill all our big trucks on oil changes and have never had a problem. It sounds like you are having the extra drained out tomorrow anyway. I don't think you could have caused any engine damage.

Let me rephrase the question? Does anyone have any information - real experience - about how much overfill is required to create damage?

I am suprised that of the 100+ people who have reviewed this post there have not been more opinions. Perhaps there is not documented cases of overfilling linked to problems with 24 valves.

 

It must be that myself and the other 100 members have all read the owners manual thoroughly, changed our own oil and never overfilled. Be patient someone will have an answer for you. We are all here to help each other.

Smokeman was only trying to help and he was right. Even though it's not the answer you requested I'm with him and you have no need to worry. Peace out!

 

Don't know if this helps any, I have a '99. I have been running one quart over full since the truck was new, never had a problem with it. Bottom end should be basically the same.

 

Could it be that they are secretly telling you just to drive and enjoy and that those 100+ are not concerned about one quart enough to do research?
I have near 400000 miles on three of these trucks (since the first one in 1989) and have yet to have even the first problem with the engine (running anywhere from 2 quarts high to three quarts low, both by mistake). Now the truck, that's a different story.

Drain it out if you're that concerned and drive on. If you had it changed somewhere, get them to document it for future reference and keep on truckin.

 

Sorry guys. I appreciate everyone's answer. In fact, the personal responses are just what I was looking for. I was not trying to be a smartass.

I was just legitimately suprised that a tech-type didn't come in and explain oil aeration and its effect on the crankshaft. I don't know much about mechanical engineering, but these boards usually have some lurking in the membership.

What I did want was personal observations and experience which is what I got. Virtual communication is sometimes less than perfect in communicating the message. I apologize if I came across as less than grateful.

Thanks again for the help.

 

No problem at all. I'm quite sue that if you can think of something to do to one of these engines, somebody on here somewhere has already been there done that.
Just drive and enjoy, life is too short to worry about the small stuff.

 

Don't feel bad about being a quart overfilled. When I took delivery of my 04 in December and decided to check the oil level with 530 miles on it. Well the dealer overfilled it by a gallon. I was in the middle of Illinois driving home to Texas from Wisconsin. Stopped at a small Dodge dealer and told the service mgr the story. He didn't even understand what was wrong. So I drove to the Autozone, bought a cheap torque wrench and drain pan and drain it in the parking lot. Drained about 4 qts out and all has been fine ever since. Did my first full oil change this weekend at 2300 miles.

Well I used that Mobile Delvac oil in mine for the first oil change and then for the second I used Amsoil 5w30 diesel oil, both were about 32 bucks a gallon, I also used a quart of the lucas oil stabilizer in this last oil change, but that was my problem, I made a mistake and added the lucas in behind the fresh oil change and overfilled it by one quart, its been that way for 8K now and no problems, I would have gotten rid of the extra quart but I have a good diesel mechanic that laughed at me when I wondered if it would do damage, I guess my answere was no. I also use the fleetguard stratapore oil filter. mine is an 03 HO

 

Thanks all of you for responding. I have relaxed now. I just overacted to the owner's manual. I think they have built in some wiggle room for error in the oil capacity.

I treat my truck like I do my dog and have the same kind of personal relationship with it. I would hate to think I did anything to harm it.

Sometimes I feel stupid for forming an attachment with, what to some people is just a piece of metal, but I guess I'm in good company.

Thanks again.

 

in order to cause a problem you would have to over fill alot 1 or 2 quarts will not cause a problem you run into a problem when you put so much in it has no plase to go so it pushes out the easiest place the seals or by the rings. it would be like plugging your breather...

Now the guy running the Lucas addative i would be more worried about putting the addative in....Go see www.bobistheoilguy.com reguarding the addative.

Sorry I was on coffee break..
I think you have done serious damage to your engine. This overfilling is not to be taken lightly. Sell your vehicle at once and get a fresh one to start over with. Now since your old truck is now damaged goods I will do you a favor and take it off your hands for....lets say 25% depreciation. That way you can sleep well knowing a tech person now owns this damaged truck and can care for it properly.

For the last 80k of my '98 Powerstroke I overfilled it by 2 quarts due to the oil leaks it had. It ran perfect (other than marking its territory all the time)

The CTD will puke out the breather hose (smell and oil) if it is overfull. If/when you change your oil put 11 in it and let it settle overnight. Top it up to the full mark. I leave mine a touch below to get rid of the breather smell.

You probably did more damage to your truck having the oil changed this early (do you really think the shop filled the oil filter???) than driving with it slightly overfull. Have fun.

 

We had a new driver at work who thought he should check the oil with the engine running. No, I am not joking. The 8.3 liter Cummins in his truck was overfilled by at least 8 quarts. This was 2 years ago, the truck still runs OK. We 'splained to him that you check the engine oil before you start the truck, and the trans fluid when it's running.

 

Agree with Peterbilt - heard of dealers filling trucks with 16 quarts....
