Low mileage ??

[Johnnyfive]

What could cause low fuel mileage? 89 240sx.I was getting 28 to 29 then It startedto drop to what I'm getting now maybe 20.When It dropped I had 148,000 miles onit and thought I needed new injectors. I had them replace and still got the same 20 milesper gallon. Put in new wires,cap,rotor, plugs.Had it timed and air filter and still the same...

I need some help.....Anybody?????????????

maybe you need a new fuel filter

i needed one on my civic cuz it was getting about 28/31 (which is pretty low for a civic), however, i didn't replace it cuz it wasn't worth it. I was in the processs of selling it anyway, so why bother

i believe if you go down to a jiffy lube, they'll change it for you...for $60, or you could do it yourself

Try a new O2 sensor

Forgot to say I put in a fuel filter but I change the filter every 30,000 miles.

leper421 I will check out the O2 sensor ...Forgot all about that...
