I thought it was bad for some mysterious emission control device (charcoal filter) if you filled-up your tank to the very top. Anyone know if this is true and why and what happens/how you know you have damaged it?

Growlor

 

i get about 18 out of my truck. has anyone ever put in an overheadconsole in a truck that didnt have one in from factory?

 

if i get 280 out of a tank i will call it lucky although mine is all wheel drive and ive got a somewhat heavy foot

All the ram guys say they are off by alot...

 

I don't have one in my dakota but I do have one in my durango and it is right on. I get between 230 to 250 miles to a tank in my dak, The only time I got 310 miles was driving up to coldfoot, AK pulling a trailer.

 

I never got more than 310 a tank and that was a 21 gal fill up. I average 16.2 and 95% of my driving is on the hi-way. I average about 75 MPH depending on traffic flow. I'll do80 to 90 MPH as long as I can but traffic on I-95 always slows to 70 so that’s where my average comes from. I can't squeak out any better than 16.8 mpgno mater how I drive.

 

Wow, I never get less than about 340 with normal driving... I have gotten over 450 miles on a tank... that was all highway driving and going about 62mph...

<3 6spd and modifications...

 

Maybe the HO is way worse. I use Plus grade gas too. I don't get it. Well I'll need to live with it until 2010-11 when I plan on getting somthing else.

 

mine is pretty much spot on too(lately thats unfortunate) but it is never higher than what i actually got
