I been running this Amsoil fuel additive fer 4-5 tanks, and this last tank I got 725 miles.725/25 is 29. Is that right! 29 mpg! I kno its a 25 gal. tank, and the 725 is correct. Anyone else getn mileage like this?

i thought my guage was shot but the sender was the problem the low level light will come on , i took my sender out and checked the wiper and found a bad spot and cleaned it good and dropped a dab of hot solder on the bad area and sanded down with my dremel and got sender working.

Im not sure if i have any diagrams but your only dealing with 2 wires , but the kicker will be if the sender resistances between the 2 are different then you will have to make up the difference by using a radio shack resistor

well anything is possible, if it was a 2x4 and it only ran on the highway, oh and if you kept your foot out of it I suppose

Goldie is a 2wd reg. cab, and those are the #'s i'm getting. I do drive all highway miles, with the exception to the store 3 blocks from my house, or when my 13 year old daughter wants to blow smoke, and thats using this gps/gas saver app on the EVO. Goldie averaged 30+ mpg on my trip to DC with the cruise set about 68-70mph (402 mile trip). The Amsoil just seemed to clean my fuel system, it gave me a slight 1-2 increase on my gps, . My buddie has a 95 that he pulls hay outa state and he says with no load he's getting 27, and then drops to 12 or so with a load. I did notice when I replaced my factory LP with 250k on it, it seemed to give me 1 more mpg, and that's where I'm at with 29 Bet if I knocked the rusty/crusty off my frame that alone would pick me up a couple more mpg .
