I changed my oil today (07 Tahoe) and added about a quart or a little more too much oil. It is showing about an inch above the highest mark, a little more than the distance between the marks. It runs fine and doesn't seem to have any problems, but I was wondering if anyone knows for sure if it is ok to run excess oil. Thanks.

 

Well it depends on who you ask some will say its ok and others would say no its bad for the seals .....I myself would drain the little bit out just pull the plug for 2 seconds and check keep doing it untill your at the level you want it to be

 

I would drain the excess.

 

Unscrew the filter and dump the oil out of it, you may have to do this a few times to get 1 qt out. (replace the filter start the motor let run a few seconds etc)

All good mechanics will agree that it is harder on an engine to have a quart too much oil then a quart too little.

 

1 qrt shouldn't hurt anything IMO
