- I'm not so sure about this. I, for one, get worse gas mileage running with
- the *blended* gas. I was getting about 23 mpg with *normal* gas now I get
- about 20. The gas is a 15% MTBE blend. So, doing some quick math, say I've
- got a 20 gal. tank... I could've gone 60 miles further with normal gas (3*20);
- 15% of 20 gallons is 3 (hey there's my 3 mpg loss!), so I've got to buy more
- of the blended gas to get the same distance as I got from the normal gas.
- Unless this mixture is actually burning cleaner, I fail to see the *benefit*
- of running blended fuels.
