How much gas do 1989 mustang gt waste?
seeing as how the engines run on gas I would say very little
but seriously,you honestly expect us to automatically know the exact percentage/amount of fuel the engine of a random year mustang does/doesn't use w/ every stroke/cycle???
Cause the fact is if you're driving a GT Mustang, fuel consumption probably isn't your top priority,seeing as how it's all ready well known V8's are gas guzzlers.
good news is they did make a 4-cylinder model for a few years, so you might want to look into that
