Have a 2009 fit sport manual transmission in Washington DC area. 225k miles. Engine using. 1 qt. Per 800 miles. I’m trying to keep this car . Dealer quotes 15k for a new engine. Too much. Looking into remanufactured engine, but they’re rare and. The only company offering one has terrible reviews. So I thought to get a younger engine from a yard. Car-parts has them and sometimes they put a mileage in the entry for the engine. Can you believe that mileage, can it be verified ? Not sure what to do. Some say just keep pouring oil in. I can do that, but will it kill the catalytic converter?
