Look at the TA go. from Alamogordo NM to texas staium and back the TA used only 42.35 gallons of fuel. Full tank when I left and filled it up 1438 miles later when I got home. Not to bad for a V-8. I had the cut out open, maybe that helped.

ohhhhhhh you suck!
I did a 600 mile trip a few days ago on straight Highway (I-80) and still got like 22 to the gallon. Btw I was thinking...what is the optimal speed to cruise at in a 3.4 v6 for gas mileage?

I would guess it would be whatever speed kept you in the lowest rpm's in the highest gear. Although my allante(which had the ability to keep track of my mpg) got its best mpg at 63 mph, atleast while useing cruise control. That ended up being about 1600-1700 rpm's.Originally posted by '94 White Devilohhhhhhh you suck!

I'll bet that you have 2.73 rear gears. With that gear ratio and a 6 speed, that's the highway cruiser gas mileage king. Congrats!

My ride is a 93 Firebird 3.4 A4, with 3.23's in the rear. Last year I went to the Corvette Museum in Bowling Green, I got 28 mpg running around 80mph with the A/C the whole way. Seeing how I was only expecting 24 or 25, I was pleasantly surprised.LarryMow-93 V6 Firebird-No engine mods-Z06 Wheels, '98 Taillights,'98 Center Console-SLP fan switch-BMR STB, F/R Swaybars, PHB,LCA,Torque Arm, SFC, Bilsteins, Eibachs....www.cardomain.com/ride/2489691/1Comment

I am not sure what the rear end ration is. I had the cruise control set at 84mph on the way there and it was at about 1800 RPM's. I though all M6's came with the same rear end.Originally posted by Joe 13201999 Ram Air Trans Am. M6

Ya know, I think you are right. It's possible that some of the autos came with 2.73s. I know my 93 M6 came with 2.73s and it's a great highway cruiser.Originally posted by Jeff 95 Z28Comment

The 93s had a different M6 than the 94-97 (and 98-02). I think the 93s came standard with 2.73s and the 94-02s had a 3.42 standard. Let me amend my previous statement.Originally posted by Joe 13202002 Electron Blue Vette, 1SC, FE3/Z51, G92 3.15 gears, 308.9 RWHP 321.7 RWTQ (before any mods), SLP headers, Z06 exhaust, MSD Ignition Wires, AC Delco Iridium Spark Plugs, 160 t-stat, lots of ECM tuning

93 was the only year a M6 could be had with anything but a 3.42:1 rear. There were two different M6 transmissions that year as well. They had different ratios.Originally posted by Joe 1320Tracy

And in terms of gas mileage, my 3.73 auto is a hog.Originally posted by ryan342.73 A4 here
Then again, that's not exactly why I own it.
funny though....... my 94 with a 3.4 with 3.42 gears only gets about 26 on the highway tops. That extra gear ratio really does put your mileage in the toilet in a hurry. Now that I'm driving the WS6 daily, I almost want to swap the 3.73 rear and use the 2.73 out of the 93 and go for gas mileage.Comment
