I just drove from my house in Katy down to Fuchaun, LA and back. I had to "babysit" a rig. Anyway i kept an eye on the boost gauge and figured if I kept my speed to where I wasnt making more than 3psi boost then there was minimum load on the engine. Most of the trip down I kept it around 63-65mph and got 25.43mpg. On the way back I was tired and cranky and only kept the boost low half the time. I mostly wanted to get home and cruised 70mph the last half of the trip home. The trip home I averaged 24.86mpg. Overall I'm pleased with the mileage, but I will be trying to squeeze about 2 more mpg out of it. The trip down I was running B100 also because it was only $2.8x in north houston.

 

wow, wish i could say the same. Then again i never drive all highway and my right foot does get pretty heavy at times

 

Lucky you. I cant seem to pass 19.7mpg

 

19?? WOW, my dad's 93 is only gettin 11 ish on summer blend.

 

Those are some great numbers. I decided to buy mom's old Celica for mileage (40 combined, hand calc, gps verified) and I'll drive the truck however I darn well please. I didn't buy a 3-ton cinderblock with wheels for the economy

 

Sweet Numbers!!!! I bet a single stack would gain you another mpg.

 

I was thinking about 5" slash cut stacks, but want a big aux fuel tank so I am going to get a 4" turboback. Plus I want it loud enough for others to hear it, but not too loud inside.

 

IMHO stacks are quieter cruising than turbo-back but much louder when accelerating.

 

fouchon's kinda at the end of the world aint it. thats great mileage. best mine will get is 22 on the highway at 68 mph

Awesome MPGs it's nice to know that trucks made in the early 90s get better MPGs than todays trucks. I know trucks today have more power but you look at much diesel cost in 1993 compared to 2008. Kind of backwards. Anyway Congrats to your MPGs

 

Better MPG - that is one of the reasons why I miss my 92.

 

I can't get that good since I put my old smokey fuel pin in. I might try turning my starwheel out a turn before going on a 11hr round trip this weekend.

yea i have the same problem except my pedal must be tired cause it likes to rest against the floor board most of the time
