FWIW - my 2 cents, i also believe that the type of gas you use is also very important. to keep a long story short. took our 03 Impala on vacation two years ago, started in montana went south through nevada ,west to California, 3500 miles, kept very close track of where we bought gas and what company. here are my results. Exxon - 22-24 mpg. mobile,conaco. 24-26. there were others but they were all in the 24-26 range, except for Sinclair. 28- 34 mpg. needless to say all my gas is Sinclair and it is consistant 28 -- 32 mpg.

That is not a result of the gas, but of the pink air you have been able to get there since 1966!!! (or was that Fina?)

Dave have you done anything with the an adjustable vacuum advance POT on your dizzy? You can squeeze out a few more mpg with that upgrade, and get better throttle response! Mine cost about $15...

I think the whole fuel consumption thing has to do with the grade of the road? ie,
going down hill one way and up hill the other....lol?

The you need to re-curve the Dizzy! It is pretty easy to do! I read an article on it, and duplicated what they did, and it made a big difference.
