    Hey, this is probably a pretty dumb question but is fresh, new motor oil flammable? If I were to get a lit match and throw it into a bottle of Castrol motor oil, would it catch on fire like gasoline?

    No it wouldn't....science ownz joo!! ;)

    Motor oil is much less flammable than gasoline. And it is the vapours from a volatile liquid that will result in fire, not the liquid itself. The flash point of typical motor oil, as provided by EMTguy's sheet, is 405*F. This means that the oil must be heated to this temperature before it releases enough vapours to ignite from a nearby flame.

    Dropping a match into it will not cause it to explode, or even ignite. I have done it before, and if I had a video source, I would do it with my face 6" away to prove it. Dropping the match into the oil extenguishes the flame, because immersion in the liquid cuts off it's oxygen supply. Now if you soak paper or something with oil, and try to light it, you end up with a smoky stinky fire, and one that burns a little faster than normal, but that's it.

    Now gasoline has a flash point of -49*F....which obviously means that at any normally encountered temperatures, it is releasing enough vapours to ignite. I have actually seen people manage to drop a lit match into gasoline without touching it off, but I would NOT advise trying it, and I wouldn't do it myself.

    You guys didn't play with fire nearly enough as a child!! :crazy:

    Edit: To the original poster....I just hafta know why you are asking this question. :uhh: For the record...I solemnly swear that putting a flame into or near a potentially flammable liquid is a REAL BAD IDEA. So if you blow yourself up dude, it's on your own horribly disfigured ass! :)

    no man, I have MUCH better things to do with my time than lighting motor oil on fire. :) But your answer makes a lot of sense, and I was just asking this question out of sheer curiosity.

    Now that I know motor oil won't ignite, I can make bets on it with people and win money. :)
