Whoa! Lousy Mileage in the Garage!
 
I parked the Cobra in my garage in December with the battery tender. We have had a wet spring and today was the first gas I bought. It seems as though 3.5 gallons evaporated out of my tank over the 4 months! Is that possible? I keep really good records on my mileage and I got 9 MPG on this tank when I drove it only 118 miles. I usually get 13 MPG. I have a good gas cap (I think), so I'm really surprised. This was my first winter, is this common?

WardL .... entirely possible as the new fuels are entirely different from what we used to get . I was talking to a performance carb shop the other day trying to find out why my float bowls were dry after several weeks .... and no fuel puddling on the manifold floor . That`s when he told me about the fuel evaporation .... also , your tank isn`t a sealed unit , so fuel can and will evaporate .

WardL, so how many times did you sit in the car and go vroom, varoom? As I understand it from these threads there is a decidedly symbiotic relationship between the car and owner and even though the car was garaged, it did not fully comprehend and thus it assimilated your emotions cranked itself into virtual overdrive and thus experienced a loss of fuel because it visualized it was on the track. Sounds plausible to me, did you notice a high state of tension from the Cobra when you emitted the vroom, varoom, just curious?:LOL::LOL::LOL:

Any counter arguments to this hypothesis, evaporation notwithstanding?

Cheers,tin-man

The fuel we are offered or forced to use today is very hard on the systems and if you neglect it,plan on all kinds of problems.

If your car or anything else is going to set for a period of time, add Stabil or drain the tank. This stuff they pass off as gasoline today is a joke around here. I add some of my 110 racing gas to the tank from time to time and that really helps. Also I can get 93 octane unleaded without any of the Ethanol/Alcohol in it and that makes a big difference but I haven't had to take any of my lawn and garden equipment in to have it worked on.

Any kids needing gas for a motor cycle, 4-wheeler, snow mobile, etc.?

Siphon hoses work well!

I don't see 3 gallons evaporating, but maybe a couple. That's a gut feel - no science.

ETHANOL!! WHAT A DEAL!!

-costs more to produce a gallon of ethanol than a gallon of gasoline-
-gallon of ethanol has about 85% of the energy of a gallon of gasoline-
-your fed. govt. subsidizes the production of ethanol with your tax dollars-
-every kernal of corn used to make ethanol drives up the price of any food products made with corn-
-ethanol is death on any open fuel system (currently spending $400+ to repair the fuel system on my outboard motor)-


WHAT COULD BE B ETTER THAN YOUR GOVERMNMENT AT WORK!!!!

Hey Ron,

Do you have any experience/opinions on the use of octane booster?

agreed......look at food labels, how many are sweetened with "high fructose corn syrup"? When the price of corn went up, the farmers are forced to feed other grains to livestock, so the price of all other grains went up substanially too! Corn > ethanol is taking food off of our table, either directly or indirectly.

And, corn > ethanol is NOT sustainable for the long term. Maybe with switchgrass or some other feed stock. Time will tell.
