Has anyone watched a fuel tanker pull into a gas station to fill the holding tanks? Has anyone ever noticed there are usually only two underground holding tanks?
One for gas and one for diesel fuel, I worked for a company that built the pumps. The fuel octane is added to the gas in the pump head there are canisters of octane additive that mix with the gas as its being pumped. You’re a lot better off using regular grade gas from upper grade companies and adding your own octane it’s cheaper and then you know what you’re getting for sure. Not mention 4 percent octane in the fuel mixture swapping back and forth for 10 to 15 gallons of fuel your not going to notice a real difference. Also using fuels from different companies you’re not getting an accurate fuel mixture anyway IMHO.
