I've got over 18 mpg with my carb before...including some autocross runs in those tanks. I regularly average over 15 mpg with a mix of city and highway driving.

Of course, I run a Quadrajet...so that's kind of like cheating at this game. ;)

Lance get it straight.......it's a QuadraToilet! :D

You just wait I'll get the Ultra XP over 20 being nice and 15-16 spirited hwy driving.......spirited for a 57 year old anyway. :unibrow:

Gas mileage talk on a performance forum... :waveflag:

Where's the like button on here!!

To me, fuel mileage just means the carb is running efficient and not just dumping fuel into the manifold hoping it burns.

If you can get 18 mpg with EFI, why couldn't you also get 18 mpg with a properly tuned carb? It's just getting it properly tuned that is the difficult part.

Sieg has hit rock bottom.

Fuel mileage = AFR
AFR = Power
Gas mileage = Range
Range = Finishing

Jackstands for two years = Rock bottom
No car = Bottom feeder

How rude of you to talk about Rob like that when he's not around these days.

Hey, the man has an 89 Grand Cherokee. Give him the street cred he deserves.

Funny I used to laugh at those wanting gas
mileage... My pantera had a blown power valve and
no gasket between the base plate and carb (engine builder senior moment)
One made it rich and the other lean...and very edgy

Had the carb reworked recently and now it is smoother and
actually easier to run on the track in and out of turns... not
edgy but smooth

I can also jump in it and run to Monterey and back and make it
Before it was real dicey and never get on it or I had to stop at
the gas station

I still run it and the Bird Rich as I still fear the lean and blow up thing

I had so much fun in my pro touring car that I got sick of it and sold it. Jealousy is not healthy, buddy ro. haha
