My son is helping elderly neighbors who have not driven their car since August. (Make, year, mileage unknown.) Not surprising that the battery is dead. His concern is about the quality of the gasoline in the tank. Google has given him many sources that suggest the car NOT be started because of potential damage from running it on bad gas. Rather, drain the gas (which will mean towing it to a shop).
He turned to me for advice, but this is beyond my ken. What do you experts recommend? He’s in the DC suburbs – temperatures not too extreme.
