I discovered dealer over filled the oil in my GMC truck when he changed it. About a quart.

jeffcat · Sep 4, 2017

Probably not worth the hassel. Just drain it down a little. Buuuuutttt....... let me tell ya another. Had a Chevy Astro van for a company truck. Jiffy lube place changed the oil. Now I always stand by the door to the bay and watch. Well they got all done and I had been chatting with the manager. They started the van and it just didn't sound right. Had a labored sound to it. Really labored !!! They had filled the crank case TWICE !!

It's a gm it will burn it by next oil change.lol
Another good story about oil changes. When I work for the deeere dealer they had a summer helper for mowing and cleaning. He like to hang out in the shop and help but he was Sort a slow if you know what I mean. So any way he was going to change the oil in one of the shop trucks, long story on filter and plug after that I told him to fill it with oil..and he did...till it was coming out the fill hole!

Better check the tranny. Heard of one that drained the tranny & added to the engine.

Nothing, mine get overfilled all the time, usually because I can't remember if they take 4.5 or 5 or 6qt. I just run them. One has 260000 miles on it the other has 200000 miles on it.

Take it back, let them correct it.

Can you see the filter? Wonder if they didn't change the filter is why it's over full.

sourgum · Sep 4, 2017

Depends on the age of the truck, probably not be too bad on a high mileage engine an older engine or just a beater truck that never gets over 45 mph. If newer truck and have a good place to get under it, would take some out of it. They say it hard on crank seals to run overfilled. People often run few ounces over full but not a quart.

just remove the filter and drain that once it fills again the level will be close, as long as its not so full that the spinning crankshaft whips the oil into a foam, it wont hurt anything , i doubt 1 quart will raise the level enough to hit the crank

pete black · Sep 4, 2017

I agree, take it back so they are aware for future.

I second just emptying the filter and replacing it.

Reminds me of one Saturday morning when I was in a GM service department. A fellow called and asked if it was OK to drive a manual shift S-10 Blazer without any gear oil in the trans. I told him it depended on how far and how fast. Turned out he was only a couple blocks away, so I told him if he idled it over to our shop in 1st gear he probably wouldn't hurt anything.

The rest of the story was, on a Saturday morning, he was going to show his two teenage boys how to change oil in a vehicle. Only he pulled the drain plug on the transmission instead of the engine oil pan. Then the filler plug on the trans was high enough that it took gear oil under pressure to refill it.

What was that about the blind leading the blind?

Stroby · Sep 4, 2017

Yup, and this time watch them do what they're doing.....I don't care what the sign says!

Ray · Sep 4, 2017

A quart won't hurt anything. I've had new trucks that were over full from the factory.More than that I would probably complain.That's why I stared changing my own.

Geo-TH,In · Sep 4, 2017

90K on my 10 year old GMC. 80K on 12 year old buick. 120k on Chevy car. NONE OF THEN USE A DROP OF OIL BETWEEN OIL CHANGES AT 3K..

Andy Martin · Sep 4, 2017

I would change my own oil.

rrlund · Sep 4, 2017

How well does he know you? There was a guy here who just couldn't leave anything alone,always had to tinker with everything. A car dealer said that if you sold him a car you'd better add an extra quart of oil and weld the hood shut. lol

banjoman09 · Sep 4, 2017

Change your own oil..if u can...but I would drain the qrt out.

pete 23 · Sep 4, 2017

Oil left on the cylinder above the top ring is burned away during combustion. All engines have to use some oil or they won't last. Many engines have short engine lift because the rings left them too dry on top. You are picking up products from the process of combustion and that is why oil level doesn't change much. That should be good for an argument or two.

I over filled a C-123 on a combine engine after doing engine repair once upon a time. The customer was upset and would not pay for that extra quart of oil on the repair ticket. I had to drain it down a bit and boss took the quart off the bill. The guy was real pain no matter what you worked on for him. Then, I moved out into the country just a mile from him for a couple years and he and all the picky neighbors got to be really easy to get along with. Funny how that works.

As far as over filling, it totally depends on the particular engine. Some use same oil pan for different applications and just change the dip stick and fill recommendations. The 400 series IH engines is a classic example of that. The D-414 in a 966 for example is about 13 quart and in the turbo charged 1066 it is 17. They got some dipsticks mixed up in production and caused a lot of confusion .

Knight George; I would go back over to the shop and pull my sword and challenge the SOBs to a match. HeHe.

My 03 with 60000 uses a quart between changes,my 98 with 90000 uses none. The 03 has a 5.3 so that probably why. My diesel trucks leak about that much.

You should get all of your friends together on Saturday morning, have a sign for each of them saying things like "shoddy workmanship" "Lousy technician" "boycott--------" and you all walk back and forth in front of the shop for the whole morning. That should teach them to be more careful.
