BIGAL8899 Posted August 29, 2011 Share Posted August 29, 2011 my gas mileage has been getting progressively worse and worse. First it was at 21.0, then jumped down to 20.7,20.5. Now i checked it this morning and its at 19.5. Why is this happening? Link to comment Share on other sites More sharing options...

robitrice Posted August 29, 2011 Share Posted August 29, 2011 ask ur right foot...honestly thats not much of a decrease. It is a fine line to keep this car in the mid to upper 20's for gas mileage. Link to comment Share on other sites More sharing options...

RJS5689 Posted August 30, 2011 Share Posted August 30, 2011 You're not relying on the trip computer for your fuel mileage, are you? Link to comment Share on other sites More sharing options...
chutrain Posted August 30, 2011 Share Posted August 30, 2011 This tank I am averaging 18.3mpg with my lead foot. It really depends on how you drive. I can stretch it on the highway and get 30mpg and around 25-26 with some local mixed in. Generally in the 21-23 range with mixed local and highway and some spirited runs.

panicrev Posted August 30, 2011 Share Posted August 30, 2011 depends on the ethanol content of the fuel too. more ethanol=less mpg. could be all of the above mentioned factors. check the gas tank for holes... Link to comment Share on other sites More sharing options...

rob-2 Posted August 30, 2011 Share Posted August 30, 2011 fill the tank, reset computer and go drive 400 miles, or till empty at 65mph. Report back computers MPG and MPG of actual miles/gallons. Link to comment Share on other sites More sharing options...

CapnJack Posted September 1, 2011 Share Posted September 1, 2011 Are you running a catted dp? To me it sounds like you are running overly rich. Can you datalog some normal driving with your AP? Something doesn't sound right. I get that kind of mileage while pulling a 1200lb trailer with my LGT. Link to comment Share on other sites More sharing options...
BIGAL8899 Posted September 1, 2011 Author Share Posted September 1, 2011 you guys were right, i filled up my tank today and let off the throttle a little bit and the mileage is better. Thanks for the info. Link to comment Share on other sites More sharing options...
LGT For ME Posted September 2, 2011 Share Posted September 2, 2011 Big AL wait till you go e85 or something equal and you'll be hoping for 16-18 mpg city miles.......... damn stock injectors and still worse than a stupid f150...wtf Link to comment Share on other sites More sharing options...
Guest PeteAWD Posted September 5, 2011 Share Posted September 5, 2011 Must use 91-93 octane, it will run less efficiently without it. Did you plug it up to an OBD II reader to see if there are any codes. It could be 10 different things, who knows? Air/Fuel Ratio sensor? But that would throw a CEL P0172.
