Stp fuel system cleaner did the impossible!

stp ultra five in warm fuel system cleaner claims to clean the tops and bottom of intake valves also these piston cramps can you believe it well we'll be testing this on fuel injectors as well because I've heard a lot of great things about STP ultra today we'll find out how to use STP and can it unclog fuel injectors well stick around you're about to find out but first let's go ahead take you inside the engine and take a look at these intake valves the tops and the bottoms then we'll show you the piston crowns as well when you see how bad this carbon buildup is you'll definitely think cleaning the inside of this engine isn't safe however not cleaning it would definitely do damage but see for yourself will we destroy the catalytic converter or will it hurt the intake valves we even perform compression tests before and after as you can see there's definitely a lot of carbon buildup and it's making its way inside the combustion chamber whether you clean it or not because it will continue to accumulate until it breaks free on its own well guys what do you think does STP have a chance at cleaning this carbon buildup or do you think it's just too late as you can see the fuel injector is definitely clogged up now can we help the spray pattern as well it's time to add the STP to the fuel tank one bottle treats up to 35 gallons now one ounce treats three gallons roughly so we'll add a little more than three ounces they really stand behind this fuel additive because they give a satisfaction guarantee it also claims to deep clean the entire fuel system even works for direct injection engines or so it states three times stronger than the regular formula increases fuel economy reduces carbon deposits and clogs fuel injectors and so many more great claims even gives your car wings I'm just kidding but with all these great claims you definitely have to be a skeptic so we got to find this out for ourselves we're going to reinstall the spark plug then drive on the highway for 10 to 15 minutes and once we've used all the fuel in the tank probably about a few days later we'll come back check out the results now while we're waiting on that test to finished we'll be seeing just how this affects a fuel injector does it even work well let's watch the spray pattern as you can see we've already added the STP to the fuel I can for sure see a difference make sure you drop a comment below letting us know what you would like to see tested next in our upcoming video but now let's go on to the compression test as we can see the fuel injector has done definitely well now we'll be showing what the compression was before we use the STP product [Music] just under 90 psi we'll go ahead add the STP product then we'll come back for the rest of the test [Music] [Music] surprisingly a 5 psi gain I'm excited to get into this combustion chamber and see just how it impacted it or if it done anything at all I definitely have my doubts but as you can see definitely a difference on the Pistons now we're going to check out the tops and bottoms of the intake valves I'm really curious to see just how it affected those as well with that much reduced carbon buildup Wow you can definitely see a reduction but around the valve that's while the reduction is on the valve not so much but there was a slight improvement even on the valves well before I use anything I definitely do my research and if you guys would like to know more information on STP just check out the link in the description below or where you can find it as you can see these intake valves well there's definitely a difference in the before and after thanks for watching Knights interactive Auto
