    I'm almost on Empty so I wanted to ask before I spent $7.00 on a bottle of that stuff. What are some good brands?

    Berrimans. It's not that expensive. It takes all the water out also. I cleaned a carb I was rebuilding with the stuff and it worked great. You can get it in the can (for adding to gas tanks) a gallon (washing carb parts, etc) and a spray bottle. It also works as a good wasp killer. Really!!

    Chevron's Techron brand is supposed to be some good stuff. Don't breathe the fumes or get it on your skin though. It has some NASTY chemicals in it!

    You can read their marketing propaganda at <A target="_blank" HREF=http://www.chevron.com/prodserv/techron/techback.html>http://www.chevron.com/prodserv/techron/techback.html</A>

    I've used the Chevron with Techron, had good results (I think...). Car seemed to run a bit smoother.

    I went ahead and got 1 pint of Berryman's and added it to my tank, and then filled up to 16 gallons of fuel. I noticed an improvement when I was driving home. The Blazer doesn't hasitate of the line anymore. Great stuff!

    I have ahd good results with the STP in the silver bottle. Run it in FI and carb vehicles and noticed improvements.
    Now I recently used the GM Top end engine cleaner on a motor I know had some carbon deposites. Well I was hoping I had a stuck valve but unfortunatly it's burnt valve and I had to pull the head. I was quite impresed with how much crud had come out with the cleaner. Now this will not clean fuel system but it will clean intake, valves and pistions.

    Grim, do you get this stuff from the dealer? And is it O2 sensor-safe?
