I've never used any. Recomendations????

 

I don't typically use any, however last summer I got a tank of bad gas. It apparently had water in it. My engine kept stalling. I poured in two bottles of "HEET" and never had a problem again. HEET is specifically made to clean up bad gas.

 

I'm a fan of the BG44K (normal formal), I buy it in packages of 3,4, or 6 cans from ebay. I usually use it once a year in my car, and somehow, every year, I end up giving a can to my sister and mother also...no wonder my suppliers aren't lasting as long. I consider it fuel system 'preventative maintenance'.

 

I too am a big fan of BG44k just use it as directed.
