15 MPG, where the last Blazer ran about 18 MPG.

A friend reccomended Berryman's B-12 gas additive.
Says it's $2.97 at Walmart. Found it at Walmart. top
shelf, and this store had only two left, so it took a
while to find it. A couple days ago, I put in one can
of that B-12 fluid. I'd checked my mileage at 15.2 on
the last tank. This next fill up came up 16.3 MPG. I
don't think I changed my driving style, and the weather
is much the same. So, I'm figure that fluid did some
good.

It may work for you, also.



This is also the time of year they reformulate the gasoline for warmer
weather. Winter blended gasoline can *really* hurt your gas mileage. So
your boost in MPG may have been a coincidence.

Need to test again in mid-summer or mid-winter so you'll have the same
gas before and after.

I'd like to see some documentation (legitimate documentation) that
proves this theory of gasoline being blended different in the winter.
