I was wondering... the stock oil change amount without a filter change is 4.1 qts. Can i safely add 5 quarts? i remember hearing about overfilling by one quart but i want to be positive before i do it.

Thanks.

(yes i searched)

A lot of people like the +1 over stock qt number. I run the stock number right now but after I change my oil when it's time, I'm definitely gonna go and do that :D

Also I always change the oil filter when I change oil.

Me too, but you never know who will forget that type of stuff. It's the same people who don't check their oil levels. :nono:

The owners manual calls for an oil change every 5,000miles, and oil and filter every 10,000mi.

why run +1qt of oil?
wouldn't the crank foam/spash up
all the extra oil= bad?

Oil sways from side to side during hard cornering and can uncover the oil pickup from being fully submerged. iirc 6qt's doesn't touch the crank, the pan is deep enough.

The 7M oil pan is PLENTY big enough to hold an extra quart and not put oil in contact with the crank. If you drive conservatively and don't corner hard and keep a good eye on you level I don't think adding an extra quart would really benefit you.


...But why not? It lessens the chances of you running dry for that split second before the awful sounds of rod knock...

Not to mention most of these engines have 100k+ miles on them, and burn/leak oil. If you're the type that doesnt make it a habit to check the oil periodically it's not going to hurt to run an extra qt for insurance.

My engine seemed to run smoother when I switched my wal-mart filter to a WIX (I bought it with the filter, haven't had the car long). Also added 5 quarts total (With filter) and it actually seems to run better. I mean smoother to say. I might be wrong but I heard in some cases it's worse to overfill due to the pressure you're putting on your pump, and possibly could lead to a burnt oil pump?

This is off the top of my head, but it made my GE run so much smoother.
