So rednecks wouldn't drink it?

Pretty much.


Third rule of rednecking: if it's liquid it can be drunk'n (drank? idk), even if it kills you.

You only can't drink stuff that burns orange (hic)

haha

05 GTP stock. Low of 16.0 high of 20.4 and an overall average of 17.9. Mixed city and highway. Car only has a 3 button and does not display mpg. All calculated from miles per tank.

Currently my truck say I'm getting 13.7, but it's likely a lie haha. More around 11-12 is my guess, I'll know when I fill up later today.

I've been going off the dic. It's at 20, which is obviously high for this time of year, but remote starting it every morning when that doesn't count against my reading will do that. I'm at about 70% city driving now though, compared to the 90% it used to be

Filled up and I was right with my previous statement.

Gas is $1.65 but I use 89 so $1.85, took 21.5 gallons and I did 239 miles so just a hair over 11 mpg lol. Only cost me $40 too.

I looked at the pump over when I was filling up and someone had bought 101 gallons of diesel fuel for $211, that stuff is $2.08 now.

Too damn cold, mileage be tanking getting like 22-24. At least gas is cheap as hell.

My non Intercooler 3.4 with headers got 28-30 highway. Port and polished supercharger and polished what I could easily reach in lim and got a constant 32-36 highway . . . Must be porting the blower that helps somehow

lol, porting a blower does nothing.

You probably fixed a vacuum leak.

my mpg are the same as they always have been. not one change from bone stock to whats in my sig now.

I'm averaging 14-15 all city stop and go. Horrible! .

I've found that the factory remote start on my 06 does not count towards gas mileage. I've reset everything after filling up with gas, drive home, and it stops at say 15mpg in my driveway and drops fast as it idles. Remote start it in the morning for 10 minutes and when I put the key in, it's right where it left off the day before and starts dropping again.
