Do you replace the car as often as your oil?

It's a big engine, but 1 quart of oil added within only 3K miles and 3.5 within 10K is a lot.
How much oil is in the engine ?

Agreed. 1 quart every 3k seems excessive unless it's being driven hard into high RPMs. However, I bought a Subaru Legacy with 119,000 miles on it, and it used a quart every 2k. I put another 100k on the engine and it continued to use oil at this rate the entire time. My MPGs actually improved over the entire life of the car, likely due to small modifications in my driving habits. The car was running strong when I parted ways after someone bought it by way of rear-ending me.
