Abstract: Use of a gasoline fuel composition comprising (a) a major portion of gasoline blending components (b) from 0 vol % to 25 vol % of oxygenated hydrocarbon and (c) from 0.01 vol % to 5 vol % of a diene compound for the purpose of increasing the injection duration at the end of a 48 hour deposit formation phase in a direct injection spark ignition engine by at least 10%.

Abstract: A gasoline fuel composition for a spark ignition internal combustion engine comprising (a) gasoline blending components, (b) renewable naphtha at a level of 10 to 30% v/v and (c) oxygenated hydrocarbon at a level of 20% v/v or less, wherein the gasoline blending components comprise (a) 0-30% v/v alkylate, (b) from 0 to 15% v/v isomerate; (c) 0 to 20% v/v catalytic cracked tops naphtha; and (d) 20% to 40% v/v of heavy reformate, wherein the total amount of alkylate, isomerate, catalytic cracked tops naphtha and heavy reformate is at least 50% v/v based on the total fuel composition, and wherein the gasoline fuel composition meets the EN228 specification. While the low octane number of renewable naphtha would normally severely restrict its blendability in gasoline to low levels, it has now been found that renewable naphtha can be included in, for example, ethanol-containing gasoline fuel compositions, in surprisingly and significantly high blend ratios of renewable naphtha to ethanol.
