I often hear people say anything with oil in it, which would include marvel mystery oil , gumout fuel system cleaner, lucas ect...lowers the fuel's octane, but I thought lower octane fuel is easier to ignite, not harder, would anything added to fuel (such as pale, light oil in some fuel additives not marketed as octane booster) . In theory wouldn't any oils in the fuel raise the octane, or am I getting this backwards?
Here's what I've noticed...low speed ping on my Rav4 is immediately and almost completely eliminated when I dump 16oz (full bottle) of 104+ injector pro in a full tank of fuel (16 gallons). I'm not exaggerating, with about 2 gallons left I'll pull up to the pump, dump the 16oz 104 injector pro in, fill the tank, start it, pull out and zero ignition ping.. I've done this 4 times over the last 6 months.. It lasts the entire tank. If I don't treat the next tank, the ping comes back.
