Oil Changes

[H2er]

I recently took my H2 in for routine service they once again overfilled my oil by 1/4 of a quart. I do not really know if this will hurt or should i remove some from the drain. the thrash marks look #### #### #### #### my oil proceeds almost up to where the number start which is about 1/4, any suggestions. The tech took the oil and messured it before he put it into the truck. it has happened once before i am really getting tired of having to take out oil. ?

H2er - 1/4 of a quart will not hurt the engine. The 6.0 liter takes a even 6 quarts. So it should be hard for the mechanic to overfill by a 1/4 . I would guess that the tech isnt letting all the oil drain down into the pan after you have shut the engine off. Is this a quickie oil change place? DO not overfill more than a 1/4 of a quart. good luck

Another idea - The tech is filling a two gallon container out of a large oil tank up to where he thinks 6 quarts is , and not actually using 1qt containers .

I would take it back and have them to take out some of the oil. This happened a few times to my wife car, and we take it back to them and they will remove some of the oil out.

I think a lot of the quick oil change places overfill to offset installing a dry filter and to prevent rework from people complaining their oil wasn't filled all the way up.

1/4 quart would barely show on the stick, my guess is if you're noticing it, then it's more than 1/4 quart.

For this very reason, I change the oil in our vehicles myself and recycle it at O'Reilly Automotive (parts store) for free. It's also a good opportunity to check everything over, grease the zerks, and prevent surprises that sometimes happen when you never crack the hood and spend time under chassis.

I have taken this this truck to 2 different GM dealers each time they overfilled by some amount i assume its a 1.4 of quart because its about the same distance as one of the 4 hash markes. The dealer says don't worry about it. I have to take the truck to there place or it will void my warranty.

i know this sounds stupid but my oil pressure has increased slighlty, maybe i should consider letting a little oil out.
