2000 Toyota Avalon Engine oil

Whats a lot a quart every oil change? Is there blue smoke while you accelerate hard? If so its your oil rings on your pistons are worn bad, or if it smokes on start up then goes away that is your valve guides on your cylinder heads worn out. I would guess for that high mileage of a car it should burn a quart every oil change. If your not sure about the smoke when you accelerate have a friend drive behind you when you accelerate hard. I wouldn't put any money into your car it will become a money pit trans engine components it will nickel and dime you.
Hope this helps. Colby
