Hey, I've had two 302 Motors in My old Fox Body Mustangs. Not one of the leaked oil.
I just saw the diss and had to put my opinion. and it is only an opinion.
But if you take care of a motor, change the oil, etc. It will last. 302's were prone to rear main oil seal leaks. One of mine got this after 154,000 miles and I just replaced the gasket. No biggie. My other I'm selling right now with 107,000 has no leaks.
Most cars will burn a little oil.
But for the thread starter. If you take care of it and change the oil regularly your car should still run even longer than 233,000 miles.
But I would change the oil every 2000 to 2500 miles. 600 miles a quart does seem a bit excessive. I used to burn one quart in my non v-tec 1.5lt civic with 155,000 miles on it every 2500 miles. And I drove it hard.
