    If a Honda push mower locks up from no oil, is there any way to save it without having to buy a new engine??

    The oil was changed about 20-25 hrs before that. Anyone know why it would lose oil so fast?

    if there is a leak, it is not a dripping one. Could it leak, where it may just look like a grass buildup??

    Some times you can unluck an engine by trying to turn it backwards. It might work, or migh not. If it works, it will proably burn oil. I was given a brand new push mower once because the guy didn't put oil in it. some tinkering, and it was good as new. So you might get lucky and un-stick it.

    The oil burned out. That is a fact. I just can't believe that after so few hours, that it would do that.

    sounds like you need to replace the short block.

    Did you pull the spark plug and try to turn the motor over?
    Does it have a blade brake or is the balde attached directly to the cranckshaft?

    Blade brake bearings can lock up motors so you think it's the engine.

    Take the plug out, maybe evenhead, squirt some oil in the cylinder, and use a wood pole with a hammer, hitting the cylinder down, turning the moter over. If the pistons not fryed or melted, it may run again. A little smoky. Its worth a try before buying a short block.
