Question for 4.0L V6 Scangauge Users

I use seasonal as being ethanol'd gas, e10 where I'm at. I think it's the EPA that decides where certain gas types need to be used. CA MA and most major metropolitan areaas are required to run it. Outside of that I don't know, some areas still only require running e10 during the winter months. If your pumps say "May contain ethanol", you might have it, but not guaranteed.

 

Ok, well I appreciate your input.

 

My mileage recently dropped with the temp changes and winter gas additives. I find that depending on the conditions 45-65mph covers the sweep spot for mpg.

 

I'm finding I get about 20.4MPG on 3 hour trips between Seattle and Portland. My best mileage is, like somebody mentioned, at around 45MPH. My best highway mileage is 65MPG. I don't really notice much mileage difference between 60 and 65 to justify going slower, but there is anoticeable dropoff at 70MPH and a bigger one at about 77MPH.

 

Damn that sucks. If I were to average 75 mph instead of 65 I'd save myself almost an hour and a half. Might just say screw it and eat the gas anyways.

 

80-85mph anon from NY-->MD I got 18.2

It seems there is a sweet spot right in there. Oh and invest in a Valentine 1 Radar Detector.

 

Ha, yeah the radar detector would come in handy. But I try to keep it within 10 over. It's considered a minor infraction and therefore cheaper on the insurance. Buuuuuuuuut, I wonder if my buddy would let me borrow his for the weekend? Good tip.

I haven't taken many trips in my truck but I've noticed with extended drives (1-2 hours at a clip), my truck gets better gas mileage cruising on the backroads at 45mph than it does going the same time (1-2hours) at 65mph.

And most definately, mine always drops with the temp change/winter gas mixtures.

 

1950 rpm, that is my trucks sweet spot

 

I'm in an access cab, but if I drive 70-75 my MPG tends to be between 16 and 18. If I keep it to 55-60, I can manage 22-26.
