Well over the summer I averaged 14.5 mpg. Within the past moth my milage has dropped to 13.5 mpg, I had 230 miles on E. I then switched to moble 1 synthetic and a new fuel filter hoping to maybe obtain 15 mpg but by the looks of it I won't even see 230 miles but more like 215 miles on E but this is taking it super easy on the gas, I never exceed 2000rpm and try to cruise at 45 mph@1500rpm on the local streets. Now I am not expecting super milage because I drive 90-95% city but there is no way I could see 14.5 mpg right now. I will see my real milage when I get gas tomorrow but I have chaged the 02 sensors and spark plugs, what else shouls I look for?

 

Mine dropped also i think they switched over to the winter gas

 

I'm starting to think your odometer is off or incorrect. I've never seen anyone butcher the mileage on an OHV that bad before.

 

Might be but it has been like this since early october.

 

I thought that to but I followed my dad home from the gas station and we both had 19.6 miles on the odometer. It is a an automatic 4x4 and like I said I drive 90% city, so I don't expect too much. I do think I deserved at least 15mpg this last time though.

 

Oh I did get gas today and I averaged 13.12 mpg. I sprayed my MAF with some cleaner but it looked clean in the first place.

 

Wow. I average 17-18mpg in the city. That's with 4.0L and 4.10s

 

Dragging brakes
Tire pressure
Winter fuel

x2 + sparkplugs , air filter

 

I know its not tire pressure, sparkplugs or airfilter. My engine is running at normal temp, vacuum seems fine, I will check the brakes again though. Could it be plug wires or the coil pack?
But between the winter fuel and the remote starter I averaged 12.5 mpg last year so I am really not going to try this winter.

 

Not if its running good. A weak spark is still a spark. You'd notice a loss in power or a misfire if it were one of those.

How cold are the temps when your driving? I notice a decent drop once they get below 50F here. I also notice when they switch to winter gas.

According to my scanguage this tank I'm only at 18.2 (norm = 20-21) It's been much colder and they have switched to winter gas round here.
