I use 11 quarts on the money. It puts it mid way through the safe range.

11 quarts is what it's supposed to hold, but there's some variation in the dipstick readings.
If you used 11 with a filter change you're good to go.
If you used 12....it's a little high but nothing to worry about.

One quart over dont hurt....my truck after an oil change will burn off one quart then never burn any more till the next change at 5000 miles Ive even put in 12 quarts and it only burns off one then its good to go

Since the -32 mornings, mine gauge shoots up to 70+ first thing then warms up and it goes back down to normal.<br> Danny
