Had the truck 2 years, and this is the farthest on a tank yet...

That puts me roughly at 21.2 MPG with nothing but a drop in K & N

they are the best

they are the best

always stirs up debates about the "right" mods, who gets what normally, what oil is the best, tires, etc... entertaining to watch really

Keep it under 65 with cruise control on relatively level roads (NoVA to Jersey) I get that going to my bro's house.

LOL, I can't get 21.2mpg downhill with a tailwind!

Mine only gets 21+ mpg at higher altitudes. Figure that one out. At lower altitudes I get 1-2 MPG less. I took a recent trip to La Pine Orgeon which is about 3K feet higher elevation than where I live in CA. Up there, on a tank I filled in CA, I was averaging 21.2 MPG. On the way home (which is mostly downhill) after I refilled the tank again in CA I averaged about 19.5 at highway trailer towing speeds.

All this and was also towing my lightweight 4X8 box trailer the entire time so my speed averaged about 62 MPH.

Well I did a 250 mile round trip from San Diego to Hollywood yesterday with 89 octane and a family of four...19.1 mpg, but I did sit in some traffic and was doing about 80 in other parts.

I've gone 443 miles on a single tank of gas. It was all highway, with average speed of 75 mph. GPS reading was 443 miles and the trip meter on the truck was at ~430. Of course it helps to have a 2wd without the added weight of larger tires and off road armor.

I wonder if at that higher elevation (in a different part of the country) they use a different type of fuel ie: +/- ethanol or another fuel addative???

I was burning California fuel both ways. That's the odd part.
