My 2.0l is getting bad mpg why?

[RangerRyan]

When I bought my truck which is a 1988 ranger with a 2.0l carb. I was getting about 25 mpg now I'm just dumping money into the tank can anyone tell me why?

well, your engine is most likely tired. my old truck had a 2.0L and it got anywhere from 18-20mpg on the highway. when you factor in that gas is over $4 a gallon as well, that doesnt help. newer gas also has ethanol in it... it also decreases fuel mileage. there are a ton of factors that could add up to your bad gas mileage.... almost too many to list.
