Oil Capacity Question/Verification

Vladimir2306 said:

I am more and more convinced that 8 quartiles of 7.6 liters will give the oil level on the dipstick in the middle. And to get the max level, you need just another 0.5 liters

Wow, this discussion went from the simple (short dipstick?), to the philosophical (metric vs English measurement), to the conspiracy of GM selling us bad design.

My service bill at the Dealer charged me for 8 quarts at $6.99 each. I can assure you that they would have charged me for 9 if they had used 9 quarts. Oil level was right in the middle of the hash marks. But wait, they did charge me $24.99 for a Premium Oil Conditioner that was not mentioned up front. That must have raised the oil level a little right? Maybe there is a conspiracy!

Where are you guys getting that it takes 8 liters vice 8 quarts,,, because GM specifically says 8 quarts or 7.6 liters

And really, holy crap, a five page thread because someone can't read a dipstick (or can't count) and thinks that their truck must be special and is different from the other literally hundreds of thousands of identical trucks out there.

Antomn you really do not offer much here.

I can assure you I can read a dipstick just fine and have been doing so for MANY years. I can also count, have been doing this for MANY years as well. You and many of the others here seem to want to make this engine meet to the written spec which maybe fine, but it is just not me, there is evidence that what I am seeing is not so uncommon. Well with 8 quarts of oil in my engine, it barely was on the bottom of the dipstick, not close to the lowest hash mark.

I think if people would stop and actually look at the disptick closely they will find 8 quarts will not be on the full mark. One additional thing everyone should note is the oil level is checked "cold" or at least after the engine has been off for 2+ hours. Checking the oil while fueling the vehicle will likely show a higher level due to fluid expansion. So following the manufactures recommendation, check the oil cold, possibly even after sitting overnight.

I will stated this ONE LAST TIME!!!!

I MATCHED THE OIL LEVEL ON THE DIPSTICK AS IT WAS FILLED FROM THE FACTORY.

8 quarts was below the the lower hash marks on the distick. I am not running an oil level any higher than when the vehicle was delivered to me. So the engine is NOT overfilled with oil as everyone seems to state, even when they have not even checked the oil in my vehicle.

Seems people have blinders on and don't see the benefit on matching the oil level the vehicle was delivered with, at the top of the hash marks on the dipstick. If you blindly put 8 quarts of oil in the engine after a oil and filter change and do not verify the engine oil level, while the engine is cold, not sure what to tell you.

Everyone can and will do what they choose, but again, if I would not have changed the oil, the engine would have had this same level, less any oil consumed until the first oil change based on the OLM which would have probably been somewhere in the range of 6000-7500 miles depending on the vehicle driving conditions. If I would have blindly folllowed the "spec", I would have an engine starting out 1 quart low on oil. Then the first time I checked it (cold) I would have then complained the engine had an oil consumption problem!

Suggest everyone pay a bit more to the oil level on the dipstick, when the vehicle has sat for more than 2 hours and see where the oil level shows up. You may be surprised, but maybe not. Just a word to the wise, pay attention to detail, regardless of what any spec states. I have found typo's, carrry overs and wrong information many times before in the automotive world and with regard to many other things. This is nothing new.

I believe it when I see/confirm it.

No need to, as nobody seems to listen or understand what I did, I MATCHED the oil level from the factory fill in my engine, FULL dipstick level from factory, FULL dipstick level after oil change. Same as shipped from factory. 8 quarts did not register in the hash marks on the dipstick. I had to add 9 quarts to match the factory level.

When I perform my next oil change, I will do the same thing, the dipstick will need to have oil to the top of the hash marks. I do not plan on running my engine 1 quart low due to some number published, I plan on the oil level being at the top of the hash marks at each oil change as I originally found the level when the vehicle was delivered to me with 6 miles.
