im certainly no expert on cars. my dad bought me a 68' jeepster commando for my first car. it should be getting at least 15 mpg if not more, but just the other day i got 47 miles on 6 gallons and was appauled

. Any ideas on what i could do to get better mileage would be greatly appreciated. i have been told it might be the timing is off, but i think thats only a part of it
