I haven't been watching crude oil prices, but gas prices sure have been plummeting. At the peak this summer, gas was $4.15/gallon at the maverik outside my office, this morning it's $1.99...

Just looked at oil... $57/barrel, no wonder :eek:

Sure makes it less painful to fill up the car. The truck is getting better too. Wish diesel would come down more.

65???

The first 300 was 35-45 in slush and packed snow, terrible mileage from the varying speeds, then 80-85 the rest of the trip. Coming back I hoped for better and kept it at 80, and got about the same.

At a steady 65 I get 18-20 (confirmed at the pump).



Maybe I should move to the 315s?

Why for? Mileage wise, it's about the same as 295's once you do the math, but with less power. The last time I tested at 65 was with the 295's, when I was doing the work at Tesoro. I would pretty much get 18 on that commute, then blow it to he!! on the surface streets, where I get 12ish.

With the dptuner, intake and muffler, I've got plenty of power but will still go back to the 295's (if I can quit replacing the 315's). My chains won't fit with the 315's.

Yeah, 18 mpg is unobtainable in my truck. Possibly if I drove at 60 mph.
 
Precisely. I can get decent mileage if I go 65ish...but when am I gonna do that???

It's in the archives somewhere, but my mileage follows my speed something like this:

55 = 25ish
60 = 20ish
65 = 18ish
72 = 16.5
78 = 14.5

At least when I had my 295's and no mods. Surface streets netted 11-13. Still do. It was easy to track cuz the meter was dead on. With the tunerchipthingy, the meter is way off.
