Who really cares either way as long as it is in a bottle....
The metric system has its limitations & some of our measurements have a reluctantcy to globalize. And thats just fine with me.

The quart will disappear in time, its just a matter of when.

All I can say is "always" is an awful loooooong time, so who knows.
When we have cars running on anti matter do we need quarts of anything?

SI units ("metric", for most part), have far less limits and is much easier to work with. Try doing engineering using the old system, with slugs and such!
The US should have just taken its lumps and converted decades ago, and by now we would not even notice it. Now the old system is just a bigger albatross.

Quarts are on their way out eventually. As far as one system being easier than the other, I have done extensive work in both and see little difference. Mostly it is what you are used to and have the equipment and data to work with. Does it make any difference whether you are multiplying by the pounds/gal or specific gravity?
Back about 1980 the government tried to see the metric system as being easier to work with. The public was too smart to buy it. We would be much better off if they honestly told people we need to be using the same system as everybody else and the soon we make the change the better. How is that for a xenophobe?

Why does coke come in 12 ounce cans and 2 liter bottles?
Why is my tire 195mm across the tread and 1 1/4 feet bead-to-bead?
With the injection molding plastic they could gear up easily for liter jugs, especially 5 liter ones that don't need a cardboard case. A teacher told me they saved the 12 oz coke cans because of the vending machine infrastructure, made sense I guess.
The only qualm would be dipsticks and pans calibrated for exactly 5 quarts, as anything more costs more at jiffy lube. My virago takes exactly 3 liters though, and Asian import cars I've had don't bother rounding to even quarts or liters!

The metric system is not our primary measurement system yet.
As a kid in the U.K. our currency was pounds, Shillings and Pennies. Our coins were 1/4 penny, 1/2 penny, Penny, 3 penny, six penny, 1 shilling, 2 shillings, 2 shillings + 6 pennies (called a Half Crown) 10 shilling note, 1 pound note, 1 guinea coin (1 pound + 1 shilling)
So there were 12 pennies = 1 shilling
20 shillings to a pound
or 240 pennies = 1 pound
Sound easy?
Well you buy 3 widgets at 3 shillings and 7 pennies each (written 3/7) how much change should you get from a 5 pound note?
The thing is, until the late 1960's we all thought this system was perfctly OK.
Is the American version imperial system any better?

I grew up with pounds,shillings and pence too - we changed to decimal currency when I went to high school.Wow,what a difference in working out money sums! Then later we went full metric,even better.There is no justification for such archaic systems,and why would the US want to hang onto a British system of measurement...didn't they have a revolution or something? I reckon the government and population are both too scared of change.

Makes it way easier to use your brain for the real task, rather than trying to remember conversions for this and that.
Equations written in metric make sense, and don't need "fudge" factors to get them to work.

I guess all the questions why hp and torque are "equal" at 5252 RPM demonstrate the ease at which imperial can be used to explain stuff.

e.g. when working with pumps, working out power, electric motors, and couplings respectively
density*gravity*Head*Flow/efficieny = sqrt(3)*Volts*Current*Cos(phase angle)*efficiency = 2*Pi*Revs per second*Torque.
And thermo is majorly easier in S.I.

What makes me laugh is they say ''The engine holds 4 quarts.'' Like,that's a gallon man! Or ''half a quart'' Duh,looks more like a pint to me.You don't have half a quart of beer! And it's a half gallon jar,not a 2 quart jar.
But the funniest thing is they are just talking litres really,an engine that holds 3 quarts holds 3 litres too.

Most of the oil I ran in my Golf came in liter bottles. Many stores now carry 5 liter jugs (stupidly named '5+ quart' jugs for Duhmerikans) for an oil change in one bottle.
I cannot wait until the US finally metricates. The metric system is an excellent, easy to use measurement system. Having done engineering both ways, it is far, far easier to use ISO units than the horrible mishmash of measurements & conversion factors for the imperial system.
I have switched my odometer to display in kilometers (recoded via VCDS, the ECU already keeps track of everything in metric) and I'm working on getting a fully metric cluster for my Golf. I even have 5m tape measures at home and my personal set of calipers are 150mm verniers.

When it comes to liters or quarts I don't see a major difference, I always treat them 1:1 for all auto fluids.
But for metric system in general, there is really no comparison and I don't see where the "limitations" may be when compared to Imerial.

In my field, there's really no standard. Some use feet and inches, some use engineering feet but most of us use metric. Different journals require different standards for notation but almost all require both metric and engineering feet. Then our clients vary based on what field they're in. For any kind of scientific calculations, metric is just so much simpler.
When I was a kid, we were told that the metric system would be standard by the time we graduated high school. I believe my parents were told the same thing.
I guess some people just really like incredibly complicated math and fractions.
