I guess I won't use shrinkage as an excuse for lower FE #s.

One day last summer, I decided to make some FE test runs so I drove about 6 miles to the station and filled up. I then drove about 25 miles or so and went back to the same station/pump and refilled. After squeezing as much gas as I possibly could into the tank, my mileage figured out to be way over 200 mpg. Apparently the fuel expanded enough to cause the mpg to be way off.

mmm

my car sits outside all the time and has a carb... yet these days despite the temperature flirting with freezing, once my car is warmed up it actually seems to drive a bit sweeter than usual... i thought it might be because it was getting more cold air, but could it just be that it's getting a richer mixture because of shrinkage?... i seem to require less throttle than before to attain a certain speed. could be something else of course....

this could alse mess up my gasslog as i have to resort to the "fill up to the brim at the same fuelpump" method to calculate my FE...

He hehe, it would be nice if one could get 200mpg+ every time a car was filled 25 miles later

Yup a second tank in the back of the car using a 45 liter beer or soda keg stainless steel and plenty of them around strong and able to withstand plenty of pressure. Top it off when the gas is cheep and pump it into the main tank when you need it.

I could do with a smaller tank, ~6lbs a gallon and I haven't come close to running out yet, so I'm probably carrying an extra 30lbs or so of fuel I don't use.

Maybe I can inflate something neoprene in my tank and pull it out before a trip?!?
