I don't know about the best brand but it surely is a pain in the arse with different vintage cars, race cars of different eras, and modern automobiles in the garages. It use to be so simple for my grandfather. He had a five thousand gallon tank for diesel fuel to heat his home( he used diesel and never home heating
oil) and a five thousand gallon tank for his cars. Now for some he had a special mixture but basically all the autos received the same gas. In the 1970's he added another tank for the unleaded cars.
Between both coasts I stay away from the pumps and rarely go near one. Only the family cars when on the road see a gas station pump.
Try to stay away from the ethanol blends. I have many friends over the years that have problems that they believe is from these fuels.
The gas he used at one time as I recall was from a facility that "cracked" as it was called from the virgin isles. The diesel was so clean and never clogged any filters on his home. He use to get a lot of fuel from companies he use to work with in the military industrial complex as we know. You don't want to know what's in that stuff!
