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.

Hmm,
Interesting, wonder what is in it. Tempted to try but I don't want to
jeopardize warranty on my brand new Acura MDX.(less than 2 months)

I don't think it will do anything for a new vehicle, it's basically
just a fuel system cleaner. But it could conceivably help out w/
cleaning gunky fuel injectors or other fuel system components in an
old, high-mileage vehicle.
