    Too Much Oil?

    How catastrophic can it be to add too much oil to these motors?

    -I know a lot about cars, man. I can look at any car's headlights and tell you exactly which way it's coming.
    -Nobody remembers the guy who finished second but the guy who finished second.
    -Speed has never killed anyone, suddenly becoming stationary… that’s what gets you.

    I don't know. I sold the car two days ago. I never had any problems. The guy that bought it rode in it for over 70 miles and then decided to buy it. He said the first night it was two quarts low and then after he added oil it started ticking. He texted me a couple hours ago telling me the car blew up. Of course the car was sold as is but I'm pretty sure he added too much oil to it.

    Could be, too much oil in the engine will become frothy and will not lubricate the components well enough. Also some of the oil will seep into the cylinders and get burned up, causing the car to smoke. As far as how much oil would do this, i don't know. Maybe 2 quarts extra is enough?... I know of people who may put in up to an extra quart of oil when they go to the track...not autocross, but road course racing, so they don't pump the pan dry. But never more than 1 extra quart. And that's not on a subaru either.

    He says it lost all power and wouldn't run. Not like it really matters. I was just wondering

    Sounds like horsecrap to me.

    Either way, the buyer was a complete idiot to add too much oil. Not your problem.

    I took my 2013 WRX for it's first oil change and told the mechanic to put in 4.5 quarts of oil(checked manual 4.4) and to start it and check the oil level. He proceeded to do that and told me it needed 5 quarts of oil. Is this the right amount of oil?

    Also what is the difference in amount of oil from the low mark and high mark on the dip stick? A quart like the Hondas?

    It's probably not too much, but our cars call for like 4.3 quarts I think. I usually put 4.5 and it's about an 1/8" from the full mark. I don't push my luck, I keep it a hair under full.

    I'm pretty sure there is a quart difference from low to full, but I can't confirm it.
