I don't know if everything is true or not... but I got this forwarded to me... and thought it was interesting.

Best gasoline tip:

Buy a Prius

 

thats hippy talk.

 

i might try that on my next two fill ups and see if there is any cost solution

 

Maybe I'm argumentative, but I don't think I buy that. The tanks are so huge that they are no doubt buried below the frost line. The temperature below that point fluctuates very minimally, and less so the further down you go. The frost line (in North American areas that see freezing temps) is typically somewhere between 2-6 feet. I am not about to spend the next few hours doing the math to create graphs showing tank depth vs ambient air temperature vs fuel temp vs volume but logic tells me those tanks are not seeing more than a VERY minute change in temperature at any time.

If you were out in the desert, would you say that it's not worth burying your feet in the sand to avoid burning them because it's the afternoon and not early morning? I know it's a crude comparison for various reasons, but there are parallels.

 

These tips are ridiculous. Unless I see some actual proof that this helps an appreciable amount, I call BS.

 

with this info, i'll save all of $.50 a year. not to mention i'll have to wake up early (when it's freezing and inconvenient), and take even longer to fill up in "slow" mode.

and if i spot a gasoline truck at my usual station, i'll have to drive to a farther gas station just because of a little dirt?

i do need to change my fuel filter though.

blech.

 

Good luck finding it in your S2000. There is none. Only a sock on the pickup.

 

You'll probably save 20 times as much fuel by simply keeping it under 85 on the freeway.

 

Bingo! My record for fuel economy is 524 miles on a single tank (10.5 gal) of gas in my civic. That works out to 49.9 mpg. I got it by going only 70 mph on the interstate, sometimes behind trucks sometimes not, accelerating slowly, and usually never use the AC.


And forget a Prius. Do a little research on "the dead zone" in Ontario where the Nickel is mined to make the batteries for the Prius.
