OK...I'm 2 for 2 now on the oil fill thing.

First oil change was done by Autobarn in Evanston. Filled to top of depression on dip stick (about 1/4 inch above FULL line).

Second oil change was done by Naperville Mazda. This time I specifically requested that the oil not be filled past the FULL line. The service manager gave me a bemused smile, and said "We are a Mazda dealership. We know how to change the oil."

When I picked up my car, I checked the dip stick. It was over filled to exactly the same place that Autobarn filled it.

Perhaps it doesn't matter, but....sheesh.

I betcha a nickel they put 4 quarts in every time

The majority of service departments do not add oil quart by quart but by using either a hose that pumps a predetermined amount or they pump it into a container to pour into the engine.

I have changed my oil all but once and truthfully the amount changes that I put in each time. If I really let the oil drain it can be over 4 quarts if I let it drain for about 15 minutes and don't jack up the one side it is less than 4 quarts to fill. That said, how many service bays will wait over 15 minutes to drain the oil? Time is money.

 

2005 Manual "Don't add engine oil over F. this may cause engine damage (8-13)." someone else do it they are not

 

going to take the time to do it right. Draining is the issue. they may know the correct amount but they don't keep tabs on how much they drained, hence overfill.
