Roger, All of those cheepy fuel additives contain methyl alcohol which is great for displacing water and doing some light clean up. The bad news is that it burns off and evaporates long before it has a chance to do the serious job of cleaning fuel intake components, intake valves combustion chambers and piston tops. This is where the products like B.G. and Maroso really come into their own. Actually their is one more level of fuel system cleaning however unless you are a pretty good driveway service technician I recommend you leave this one to the dealer. This system utilizes a pressurized can of fuel system cleaner that is hooked directly down-stream of the fuel pump. Basically what you do is disconnect the power to your fuel pump, install this can of cleaner in the supply line from the gas-tank to the engine, open the can to pressurize the system, start the engine and allow this Weasel piss to run through the entire system. Once this is completed reconnect the fuel supply line reconnect the fuel pump power and ad the second stage of the cleaner to the fuel tank and most importantly install a new fuel filter if appropriate. I'm not sure who produces this two part system but it is available from your GM dealer. Regards Larry Stansifer Thou art rewarded for thy results not for thine efforts. The Rogue Warrior
