to much oil?

[graywolf]

Ok I sold my commander and was nice so I changed the oil for the lady. I put 5 qts in and it said low so I added a half quart and it said good. She brought it back to me saying there was to much oil so I emptied the oil filter, started it and did it again. It was saying a little over the line but I figured that was the fact it was on a slope. Well the lady is now saying the check engine light is on and now she is saying it was because to much oil. She hasnt gotten it checked out but is saying if it has anything to do with to much oil we will pay. Now it was technically changed when she owned it but I know for a fact it is not because of oil that it is on. We had a trans leak so pan gasket was changed along with some sensor coupler thing on the right side of trans that was supposedly causing check engine light to come on. I believe trans is still leaking and this is the cause of the light. Dont really have a question guess just wanting your guys input on this. Oh and she knew about what was changed and that the light had come on in the past.

I did a search on net and got conflicting answers as to how much oil, some said 5qt and others said 5.5qt... Oh and in the parking spots here the back sits lower due to the slope.

You didn't mention which engine the Commander in question has so....
3.7 V-6 with filter is 5 qts.
4.7 V-8 with filter is 6 qts.
5.7 V-8 with filter is 7 qts.

Regardless of where the oil shows on the dipstick after the oil /filter have been changed and the engine run, that is the capacity.

In the event you used the incorrect oil grade in the Hemi, with M.D.S. it would likely set a check engine light.
The 4.7 and 3.7 would not be affected enouph to set a light if the incorrect grade was used.

Long term overfilling could set a light over time due to potental plug fouling.

All that aside, you put in 5 qts. and I assume you replaced the filter.
So, I am led to believe yours was/is a V-6.

As I said earlier, it was not overfilled, regardless of stick reading.
Therfore, nothing you could have done could set a C.E.L.

Even though you removed a half quart, it would not cause a oil pressure warning or C.E.L. light.

This really is a situation of 'buyer beware'......the problem occured after the sale......had you continued to operate it, the light would have gone on while in your possession.....not related to oil level IMO.

Oh sorry yes it is the v6, I did the oil change about 1hr after she had bought it as a good gesture, plus I had it just wasnt time for it to be changed. I originally put in 5qt and it was reading low so I added a half qt and it said fine. She had it for about 3-5 days than called us saying check engine light was on and that the oil was over filled. I empted the filter twice and it said a hair over but I contributed that the slope of the drive way. I mean the oil filter holds what about a half qt so it would be under 5qt... I let it drain for long enough that their couldnt of been that much oil left in the pan.

Did you start the engine prior to checking the oil? After I change my oil, I start the engine and let in run for around 30 seconds. Then I wait around 10 minutes for the oil to settle and check the oil.

[graywolf]

Yea I started it but don't think waited long enough time before checking it.

Did you happen to read the code for the check engine light?

If being overfilled even 1qt would set the check engine light off in a few days, there'd be hundreds of thousands of check engines lights going on every day from unskilled laborers servicing vehicles...... Curious what the code was.

[jchely187]

Im no expert and have consistently never filled oil to the correct level, usually over or under, I use the big jugs and its hard to tell sometimes. I have never noticed a light coming on in any of my jeeps for that. Its just a coincidence is my opinion, Sucks it didnt happen sooner huh. Just tell her to get the code read and to let you know what it is, play nice. She is just scared im sure. Think of where you would be in that situation.

i am an expert, and the chances of the oil being the cause of the check engine light are slim and none. i dont want to say it is impossible because i have seen some weird stuff over the years but i have never seen a check engine light due to overfull oil. on a side note my 07 dakota has a 3.7 in it and i put 6 qts of oil in every oil change thats a 1/2 qt overfull for that truck and have never had a problem.

most likely the check engine light is on because she didnt tighten the gas cap after she filled up. sounds stupid but i see this 20 times a day at the dealership cant believe how many people cant follow simple instructions and use common sense like tighten your fuel cap
