Modern cars sure don't burn much oil. If they do, it's time for an engine rebuild. My airplane on the other hand burns a quart of oil every five hours. Most of it is blow-by, spewing all over the belly, but engine designs of old do either burn or push a lot of oil thru the system.
LOL!
Took me awhile to get used to (as former owner of a Triumph TR-6). With that car, it was a question of "fill up the oil and top off the gas." Constant ruptured diaphragms in the CD-4 Strombergs (I carried an impact wrench and TWO sets of spares). And the electrical system . . . with a dead short designed into the wiring (which we bypassed) . . . not to mention the slow trickle drain to ground that we never could find . . . installed a battery cutoff switch in the glove box . . . somebody tried to steal it once and hotwired the ignition, but didn't look in the glove box. They gave up in disgust, leaving all the wires hanging out of the steering column. We just stuffed them back in . . . .
All that said, I loved that car. Great low-end acceleration, and it could negotiate square corners at 60 mph (guess any car could when the tops of the tires are about level with your ears.) We had to give it up when we started having babies - no place for a car seat. We sold our ancient Toyota Land Cruiser ute at the same time for the same reason.
Now we're in Fords and my 16 year old daughter has a Volvo wagon. Oh, yesterday, leave me alone . . . . :-D
