- 2015 Regal GS
I have read 5.0 US qt..... I have read 6.3 US qt...... What the hell! Some buick literature reads 5.0, some reads 6.3 for FWD! Which is it?
I missread the title and skipped the part of 2015. As LHU engines go the capacity is 6 for turbo 5 for none turbo. My guess is they made the oil pan smaller on the AWD models to accommodate the drive shaft. Which makes me also wonder if the awd versions are doing all of the failing around here.Not true..... Sorry.
This makes zero sense even if it was true. The AWD calls for 6qts so why would it have a smaller oil pan?I missread the title and skipped the part of 2015.

I agree w the dipstick final check method. I bring in a case (6 pack) of Mobil1 full syn for my AWD and that seems to level out at 100% every time, no issues.The info I posted was from the owners manual, but it's always best to check the dipstick level to get it right. My AWD Regal takes 6 quarts and that puts it over the full mark on the dipstick.
You guys got me going on this again so I went and pulled the dipstick on my 2016 2.0 turbo FWD and it looks like the AWD dipstick pictured here. The part number on my dipstick is 12654077 and I looked the number up on a GM parts site and it is the correct part number for my car. I looked up the part number of the pictured dipstick 12654314 on the left and it says that the pictured stick is for a 2014 to 2017 2.0 turbo AWD. My car is close to an oil change so I will look at things again. May be it is 5 quarts with out the oil filter. One good thing is that my car has gone 4,000 miles and the oil level did not go down.I snapped some pics of my AWD dipstick on the right and my wife's FWD dipstick on the left and mine is definitely longer in length. BUT as you can see in the pics the crosshatch and full marks are almost even, which is probably why the AWD dipstick reads over the full mark with 6 quarts of oil.
What's odd is how the lengths of the crosshatch are different. If the AWD crosshatch was extended to the length of the FWD crosshatch that would be the level where 6 quarts would come to. View attachment 17677View attachment 17678
