In the late 60's we had a 1953 Chevy pick up at used a quart every 40 miles. It was 20 miles to town so we made sure it was full before we left and just added a quart on return without checking the dipstick. :)
Even with some tool and die background I am still impressed internal combustion engines can hold together and keep running hour after hour the way they can do for many years.
While burning a quart every 40 miles is excessive in my book it still meant a poor dirt farmer had a usable truck. Gas was $.25 a gallon a quart of oil was no more than that.
I do think vehicles that need oil before they burn a tank of gas is a pain because you have to check the oil between fill ups. We have one truck while we do not have to add oil we still check the oil because it may set 4-5 months between usages just to be on the safe side plus the hood needs to be opened to check for animal nests.
Needing to add a quart every 900 miles is a non issue except for bragging rights at 'My engine does not use any oil'.
If that was technically a true statement then one would have a blown engine because they all use at least a few drops. :B
