Most people talk of quarts in a mileage sense. Well, I am thinking that we need to really see how are cars use oil.
There are many variables, such as engine size, rpms due to gear choices, steady state vs city driving etc etc.
What can we honestly due to figure out our oil consumption. I mean, if I tracked a car for an hour and used a quart after 250 miles, yet on the highway and I am cruising in OD till I hit 250 miles and I use no oil, what has changed?
I am thinking one thing tells us how we are doing with oil consumption, and that is compare it to fuel consumption.
I am no engineer, no mathematician, but if you get 10 mpg and use 1 quart of oil, then you get 20 mpg and use 1/2 quart, you will eventually see a trend.
ANyways, just a thought.

just measure it in time the motor runs.....hours/consumption

Okay, but the hours doesnt tell the whole story. If you run down the highway for 5 hours and use a quart, it cant be equal to rpms etc when you race it on a track for 5 hours.
In electronics we use hours. But an engine in a car is different. An engine in a airplane can be done by hours.

Anyone else?

im not sure exactly what your asking then....

I am asking what is the true measure of oil consumption.

Quickin

The easiest way to guage oil consumption is the amount used between oil changes, because it will take every driving condition into account that you do with your car in that time period between those changes.

Simple.

If you want to know what it burns at 2300 rpm on the highway for 4 hours, or what one will burn in 3,000 miles of stop-and-go city traffic, or anything esle, go for it, but its meaningless really, because there's not a car on earth that does ONLY that one single type of driving.
