I replaced the oil on my mom's Prius today, which is 3200 miles or so since I replaced it last. The car only takes 3 quarts of oil, but only drained a little over 2 quarts.

My jeep, on the other hand, takes 4.5quarts of oil, and drains 4.5quarts when I replace it.

I use the proper oil in the prius so I don't see why so much of it would burn off. Is this normal for this car, or should I be worried?

    They save on gas mileage by burning your oil instead?

    Depending on the model year, the Prius has 2 drain plugs. Also, the original US Prius takes 2.9 quarts, not 3. Overfilling that model is easy AND bad.

    You should use the marks on the dipstick, not the amount drained, to measure how much oil you're burning/losing. When you drain the oil, some remains in the engine, and some is in the oil filter. Commented May 10, 2013 at 18:34

1 quart every 3000 miles seems to be well within the spec for just about every Prius, so it seems almost certainly acceptable for yours ( though we still haven't heard what year yours is ).

Try the owner's manual. If that doesn't say, contact your Toyota service department and have them check the maintenance manuals. Different cars have different acceptable burn off/losses. For example, my Toyota MR2 is within specification as long as it doesn't burn more than 1 quart every 1000 miles.
