Techron is similar, but not idential to the BG 44K. The BG product is designed to be used via an induction cleaning as well. Rather than do that, you can put a whole 11oz can of 44K in 2-3 gallons of gas left in the tank and just run a heavy concentrate through, which may work better than extended dilute cleaning (11oz in a whole tank of gas) for stubborn buildup issues.
