Abstract
Additives for LPG fuels which reduce fouling, thereby increasing fuel efficiency while reducing particulates and carbon monoxide emissions, are provided. The additive compositions are produced from commonly available low cost products and comprise about 97.3 to 99.4 volume percent of a petroleum hydrocarbon which is a mixture of middle petroleum distillates and petroleum naphtha, about 0.3 to 1.5 volume percent of methanol and 0.3 to 1.2 volume percent ethoxylated alkylphenol. Optional components, such as upper cylinder lubricants, odorants and antiwear agents, may also be included in the additive composition.
