Crazy oil change on my 2012 3.8

[dougmcp]

I use a K&N air filter and clean it twice a year. I hate when those dudes use the gorilla grips to put the drain plug and filter in...it's just laziness.

My 2013 3.8 takes a full 6 quarts for an oil change.

Yea, I drained oil and changed filter, and put 6 qts in my 2012, and it was overfilled. Had to drain some out. Odd.

Are you all running regular grade fuel? (87 octane)

 

[QuantumRift]

Yes. Engine is designed to run on 87, so 91 or 93 won't help performance or mileage. 3.8L V6. Using a top tier fuel premium will give you the added benefit of cleaning agents for the injectors, but that's about it as no fuel or additives touch the intake valves.

Mines a 2013 3.8 but I have no issues with 6 quarts. Maybe there's a difference in the dipstick or the dipstick tube.
The distance on mine from the top of the dipstick tube (bottoming shoulder on the dipstick) to the full mark is exactly 24".
Here are 2 photos to explain:

I'll have to check it. I can't think they'd make a diff in oil pan size, etc from yr to yr.
