Will bg 44k hurt my engine if i fill it with chevron gas that has techron already in it?

I routinely use gas from Shell (V Nitro) and Exxon premium. I even buy bottles of Techron in addition to what's already in the gas from the pump. They don't do much. Once I put in BG44k into the tank (and drive it for about one tank's worth of miles), I can feel the power in the engine come back. Feel, meaning, the car pushes you against the seat more when you floor it. Only BG44K does that.

Whats the difference between this and the fuel system cleaner?

Chris, I don't really have experience with other fuel system cleaners. I used BG44 on my engine builders recommendation. I was having problems with my racing engine building deposits on the valves and increasing leak-down percentage. With several cylinders showing 6 to 8 % leak down, I ran the next race with 1/2 can of BG-44 in 5 gallons of 110 octane rave gas. After the race, those cylinders were all below 2% leak down. Also the intake manifold runners were sparkling clean. I now repeat this process after 40 or so 1/4 mile runs and all cylinders are still between 2 and 3 % leak down.

2008 saturn astra with fuel filter in fuel pump-will it clean this filter?

Hi 44k is strong stuff and will clean and condition ALL parts of the fuel system. Filters included.

Is this necessary if i use top tier gasoline?

I use top tier fuels (always 93 octane), but I have read and studied American Society of Petroleum Engineers findings for years. With minor exceptions all cars from 1986 forward are electronically controlled by computerized fuel injection systems, and most recently direct injection systems that place the fuel delivery nozzles in close proximity to the combustion chambers. This creates a cleanliness hazard to the injectors. So, you can avoid a $150-$200 carbon depletion cure with 1 can of BG-44K every 5000 miles or less. Yes -- it is expensive, but if you look for sales and buy in bulk you can get it for half the retail price.
