    I heard from a former drag racer that they were and are still using mothballs to boost the octane of the gasoline. How true is this? Wouldn't it harm the engine?

    sa tingin ko oo.dahil major component of gasoline is naphthalene kung saan gawa ang mothballs.

    personally, I'd rather add a higher concentration of acetone than mothballs. Napthalene is a crystal when it comes out of mixture in a compatible liquid.

    Baka rin kasi iba ang preparation/texture ng mothballs kung hahaluin sa gaso. Try nating humanap ng sites tungkol dito.

    6.20 Can mothballs increase octane?

    The legend of mothballs as an octane enhancer arose well before WWII when
    naphthalene was used as the active ingredient. Today, the majority of
    mothballs use para-dichlorobenzene in place of naphthalene, so choose
    carefully if you wish to experiment :-). There have been some concerns about
    the toxicity of para-dichlorobenzene, and naphthalene mothballs have again
    become popular. In the 1920s, typical gasoline octane ratings were 40-60
    [11], and during the 1930s and 40s, the ratings increased by approximately 20
    units as alkyl leads and improved refining processes became widespread [12].

    Naphthalene has a blending motor octane number of 90 [52], so the addition of
    a significant amount of mothballs could increase the octane, and they were
    soluble in gasoline. The amount usually required to appreciably increase the
    octane also had some adverse effects. The most obvious was due to the high
    melting point ( 80C ), when the fuel evaporated the naphthalene would
    precipitate out, blocking jets and filters. With modern gasolines,
    naphthalene is more likely to reduce the octane rating, and the amount
    required for low octane fuels will also create operational and emissions
    problems.

    Thanks for the replies. Instead of putting mothballs into my tank, I will put them inside the car. May nakita kasi akong ipis na pumasok sa loob eh.
