Mine is a 91 5L tpi engine, t-5 Trans 3.23's, 275/35/18 rear wheel. I have k&n filters, cut out air box, airfoil, manifolds and stock pipe with a Flowmaster. My last tank if fuel I got 460 Kim's out of 50.3L of regular. Works out to 25.9 mpg or 10.8 l/100 Kim's. What are you guys getting? _________________ If she's bored, she should've been stroked. 91 305-World Class T5-Pro5.0 shifter-95 rear end with 3.23's-2002 C5 rims-manifolds and y-pipe from a Player's cup car-flowmaster and custom tailpipes-custom stereo.

Put in 52L during that fill up. Wasn't babying it or intent on saving gas during that drive back. That puts me around the 28mpg mark. If in city, I get around 375 km/tank, but I usually fill up with 1/4 to go and around 300km. So it eats up a good chunk more gas in city for me. _________________ 2017 Corvette C7 Z06 Admiral Blue 1998 Camaro Z/28 Mystic Teal Retired 2005 Corvette C6 Z51 Lemans Blue 2005 Corvette C6 Z51 Torch Red 1988 Camaro SC Maui Blue

I am pretty happy with that, considering if I do the same run in a brand new 4 cylinder car (couple weeks back I did a new Kia Forte) I get about 7.5L/100km.

With the built 355 h/c motor I got about 400-450 maybe more if I could keep my foot out of the throttle The 69 I have no idea the odometer doesn't work lol. Doesn't appear to be bad for a carbed L6 _________________ 1969 Firebird Sprint OHC 6 - 250ci/M5 1995 Trans Am - Blue Green Chameleon - 350ci/A4 1994 Fire-Am - Polo Green - 355ci/M6 380rwhp: SOLD
