Oil Capacity Question/Verification

[Vladimir2306]

Listen, the information about different probe lengths is very interesting. Considering that our engines actively consume oil, maybe GM decided to play it safe? by shortening the probes?

 

[Vladimir2306]

So let me ask you this, playing devils advocate. If you continue to run 9 quarts and eventually have engine troubles. You're warranty claims will be denied because you are not using the specified amount of oil. You are willingly neglecting it.

You can run around the logic in your head as much as you want. But the spec is 8 quarts! Why mess with it. Overfilling oil leads to aerating the oil, which leads to foaming, which leads to oil starvation, oil starvation = bad.

Sorry if that's not what you want to hear. You came here asking for advice, the correct advice was supplied.

Nothing will happen to the engine if the oil level is 0.5 liters above the maximum level. Where does aeration come from? where does the foaming come from? This only happens when water gets into the oil.

Exactly. On an 8-quart engine, a half a qt over is nothing at all to worry about.

No)) I already wrote that filling the oil volume to 8 liters, not 8 quarts, but precisely 8 liters, gives the Max level on the dipstick. overfilling another 0.5 liters will not cause any problems for the engine. Most likely, this additional volume was initially included by the manufacturer to add fuel, which can be up to 4-5% of the oil volume.
I think with an 8 quart fill you get an oil level midway between min and max. By filling 8 liters, we get the Max level.

Foaming and aeration is caused when the oil level in the pan is too high and the crankshaft splashes through the oil thousands of times per minute. At the proper fill level the crankshaft is above the oil and not traveling through it.

Let's remember what the L87 looks like and where its crankshaft is located. I can’t even imagine how much oil needs to be poured in there for the level to reach the crankshaft. Obviously not 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!

 

[Antonm]

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 literally hundreds of thousands of other identical trucks out there.

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

 

[PPV_2018]

Wow, this discussion went from the simple

This “discussion” wasn’t simple from jump street

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

yeah, right, this was the part that was confusing me. I know us Americans don’t know much about the metric system, but qt ≠ L

Be convinced all the want,,, remember that every dead body on mount Everest once belonged to a person convinced they could climb the mountain,,, being convinced doesn't make you right.

The oil level was in the middle of the dipstick hash marks with 8 quarts, plus likely a pint of some "Premium Oil Conditioner". So this tracks pretty much what I am seeing that 9 quarts to the top of the dipstick.

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.

After reading all the comments I’m wondering if perhaps in their required pre-delivery checks a technician noticed a low oil condition on the dipstick and added oil before delivery. It might help eliminate one possibility if someone with the same model & engine would post the exact length of their dipstick so you could compare lengths.

 

[GMCnewbee]

Well, I certainly do not want to be told that I might have a short dipstick.

 

[Vladimir2306]

Now I talked to the service where my Yukon serves. They pour 8.2 liters into the engine. I note that it is Liters, and not a quart in the engine to the max. Another nuance, in the USA you usually buy canisters of 1 quart, and we buy 5 liters. When draining a canister of 1 quart, about 30-40 ml of oil remains in the canister. 9 canisters of 30-40 ml is 300 ml of oil that you did not drain into the engine

 

[yamahamaxim1982]

I got a 5.3. Same oil capacity 8qta. Changed oil filed 8 qts and started it up. Turned it off and nothing on the dip stick. Added another 1/2 qt and now she shows it on the dip stick. I was also on flat ground when I checked it.

 

[DocDoug]

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.

The problem with your factory fill theory is that the dealer is responsible for doing a pre-sale inspection and that requires checking the fluid levels. If they did this, they may have added oil to bring it up to the “proper” level on the dipstick. Just compare your dipstick to another one and be done with this silliness.

 

[mwswarrior]

6.2 L, 130,000 miles of oil changes, 8 qts every time as designed, running perfectly.

LOL, you're right, your truck is special and holds more oil than every other one made, you have that 1-of-1 special model. Have fun with it.
