Sept 15th is the last day that gasoline retailers are required by the EPA to sell Summer mix fuel. Why do you care? Well summer mix fuel has a lower
RVP (Reid Vapor Pressure) number. The lower the number the less likely that you will experience Vapor Lock problems. Also there is slightly more
BTU's (energy) per gallon in Summer mix fuel. So in 49 states and some US territories, starting on Thursday morning they can sell anything they
want. This does not apply to the Peoples Republic of Kalifornia and the EPA non-attainment counties across the rest of the US.

There are some strange anomalies in the RVP requirements table. Like why are some areas of Michigan and Kansas the same as El Paso and Phoenix (7.0)
So if you need gas in your GMC or anything else, today or tomorrow are the days to go fill up.
