Deposits on cylinders arent bad, as they help with compression. I would be more interested with how the injectors and valves looked pre and after, that sludge on the top of the piston makes zero difference, but if your valves are not shutting completely because they are dirty, then you'll loose power.

I use a PEA version of gumout and I use a bottle to half a tank and then do some occasional it's,Ian tuneup runs during that time. I'll then fill up like normal. You'll see a big difference with the boroscope in those harder carbon deposits. Only PEA and getting those interior cylinders really hot /collier for a few cycles witll get the crust carbon off.

Fundamentally the fuel grade matters. eg: 91 Octane (Premium) has no ethanol. If you use the lower (cheaper) octane, like 87 or 89, you will introduce excess carbon deposits into your fuel system. Therefore, fuel cleaner is rendered irrelevant if you use cheaper fuel. Use the more expensive 91 octane and you wont need fuel additives.

The label clearly says " Improves Gas Mileage and Performance in Just One Fill Up" , I'm sure it cleaned your injectors, resulting in better gas mileage and smoother idle. NOWHERE does it claim to clean 17yrs of carbon build up from a 17yr old neglected engines Pistons.

Nobody should expect a 5oz bottle of cleaned added to 15 gallons of fuel, to clean deposits from years and over 100k miles of neglect. Use this type of product with every fill up since new, and you will never get those deposits. I use Lucas with every fill up since new, and my piston heads look as new, without the slighted carbon deposit.

What I have found is that fuel injector cleaners with a high concentration of the chemical PPE is most effective. Engineering Explained has also done a test on that as well. Also, with working in various garages and auto parts stores, I found that high end and high dollar cleaners work the best.

I think the idea would be to use this and other products like this over the life of the engine starting from the beginning so it never builds up in large amounts.

Chris, the best would be test engine power on dyno before and after. I think dirty piston is not so important. But if this liquid can clean fuel injectors... I use similar products for diesel, here in Poland. After application I see significant engine noise reduction, engine idle is more smooth, small reduction of fuel consumption , less fumes from exhaust.

I don't recommend this stuff at all because you have to put it in every tankful for about 10 fills to initially clean a dirty engine. Then every 5th tankful to keep it clean. It is waaaaaay too expensive too. I recommend something else. Way too many variables. New - correct - spark plugs....at the correct gap? Platinum is verified as providing a hotter spark to set off the fuel. Ignition system weak? A weak spark can cause a bad explosion in the combustion chamber. Good fuel used (not cheap crap from a grocery store)....as recommended in the glove-box manual? Octane rating? If your small car calls for 87 octane and you are putting in 92 then the carbon builds up 10x faster because the fuel burns slower and not completely. Clean air filter? Fram is the best because that is what all engines are designed for. Oil going down through the sleeves on the valve stems? How did the valves look when looking down the intake and exhaust? Looked like it was happening on a couple of cylinders to me. Proper oil in the crankcase and new? Injectors clean? Bad spray-mist equals bad combustion. Catalytic converter plugged? Muffler plugged? If the burned air cannot leave the combustion chamber then it will build up and foul the incoming fresh air for the next cycle. Water in your muffler is one of the biggest problems with the 'unleaded' fuel systems. Drill a couple of small (1/16 inch) holes....one in the front and one in the rear on the bottom to drain the water and keep it out. NOT THE CAT...you will ruin it!!! Moist air in humid areas can cause faster and heavier carbon build-up. Remember, water doesn't burn. That is why I recommend putting a bottle of HEET (red bottle) in your tank before you add fuel EVERY fill-up to keep the water burnable and your injectors clean. There is ALWAYS water in fuel. The red bottle has injector cleaner.....the yellow bottle is cheaper and only has water mixer. Both mix with water to make it burnable but the red bottle states it has injector cleaner....good stuff. $2 at WALMART. EVERY TANKFUL!!!!! YEAR 'ROUND!!!! Very cheap investment to keep a good running motor. - FREE ADVICE - from a Master Mechanic/Technician who knows the science of these engine systems......I hope it helps you
