i have a 89 gtu. when i full my gas tank up the frest half is gone in like 50miles. i get about 160 after that. i know i dont have a hole in the tank. does anyone know y that is?

 

210 miles to the tank...you prolly fill up around 1/4 left so... 210 for 3/4 of the tank...16 gallon tank



makes sense







if you had a hole in your tank you would know...why would you think that

 

what can we say Rx7s get shitty gas milage

 

The gauge on the stock cluster is not that accurate. As an example, I've driven three different n/a S4's and all three have had different tendencies with the fuel level on the gauge. Personally, I prefer the quicker at first then slower near the bottom, it allows you to put off filling up longer



Find out you mpg and then we'll see if there's a problem.



Other ideas?

Leaking injectors, heavy foot, clogged cat, etc.

 

yeah you need to figure out the mpg, the guage isnt accurate enough

 

about 11 mpg does that sound right ?

 

nope it should be more like 18-20, look at changing your 02 sensor

 

02 sensor is where its at! *slaps j9 on the butt* good game!

 

water is more expensive than gas..... a 20oz bottle of water is a dollar, go figure....

 

So true
