Good luck with this one Jake.... I'll file that info for later.
I'd also like to add the fact that the same bulletin you are speaking of also very clearly states that with the NorthStar the oil should be checked with the engine hot, after it has been shut off at least 15 minutes. This will allow the oil to drain down and give the dipstick the most accurate reading.The owner's manual speaks about proper oil levels and indicates that the upper hash mark is the highest the oil should ever be.
The subject of MANY posts in here, the current GM TSB for FWD Northstar oil fill procedures also gives specific guidance for oil level.
The result of all those words is that the normal oil level indication for a Northstar engine, properly filled with 7.5 quarts of oil, is just about halfway up the dipstick hashmark :
<----ADD XXXXXXXXXXX OPERATING RANGE <-------
If you habitually carry the oil level at or just above the top hash mark you are running the engine with 0.5 to 1 quart overfill, and that's also addressed in the TSB as being a contributor to complaints of excess oil consumption: The engine will rapidly burn/leak that extra oil, so if you attempt to carry the level at the top hash mark you're simply throwing oil on the street. In truth, a Northstar will be perfectly happy with the oil at the bottom hash mark all the time. I carry the level at somewhere between the bottom mark and halfway and get 4,500 miles to a quart of Pennzoil 5W-30 synthetic. .....
Yeah, I too only use 7 qts. It's just easier.When I do an oil change I put 7 quarts in. With 7 quarts in the engine I'm just about where the red X is. So that seems that the specified 7.5 quarts would almost get us to the top of the cross thatching, no?
