[QUOTE="RossKean, post: 1444904, member: 19880"] It surprises me that they run winter blends in a hot summer. (Not saying that they don't) I don't know what it does to tailpipe emissions in terms of ozone/hydrocarbons/CO/NOx etc., but winter blends contain higher concentrations of volatiles and will contribute more to hydrocarbon emissions due to simple evaporation. Charcoal canister doesn't get it all and becomes saturated quickly. Greater likelihood of vapor lock as well. [/QUOTE]
