I just got a 1988 ford cobra motorhome. I drive home about 120 miles and I had to get gas 3 times. $60 first $88 then $70. I the fuel pump is new according to seller but the gas seems to have gone too quickly. Any suggestions as to what the cause might be or is this normal?
Back of the napkin, At $3.50 you got about 62 gals of fuel. At an avg of 8 mpg your range should be almost 500 miles. Now we don't know how much fuel you used on the last fill up but for the sake of argument you used it all, you're getting about 2 mpg. Definitely a problem. As far as diagnosing your problem, no one can armchair this one based on the information, or lack of.
You do not state the details. How big of a motor, how much the unit weighs and how many gallons of gas. Price of gas means nothing as $218 could buy you 82 gallons in South Carolina and about 38 gallons in California. Chances are you have a large engine that may even need premium gas. A rough guess is that a unit of that era would get between 6 and 10 mpg. Add age and wear to the equation and it may creep down to less than that. Come back with some details and we will try to help you.
