I’m just writing to say how happy I am to have used your Fuel Injection Cleaner in my Porsche, It was slightly surging in the low end of the gears, so I thought it must be dirty injectors so I went and purchased a can of Liqui-Moly Fuel Injection Cleaner, put it in the tank and within an hour there was no surging what so ever, no matter how hard I tried to replicate it. The Injector Cleaner must have cleaned the injectors proper! It’s very hard to buy a product these days that does what it says it can do, but Liqui-Moly seems to honour their word! thanks again and I will be sure to use your products again!
