I have used several products that I know work to clean fuel systems out and improve performance. However this is the first product available that directly targets Turbos and EGR valves. The modern diesel with its complicated emmisions control systems, has one huge downfall! The recirculation of the gases through the EGR valve and ultimately through the turbo, means sooty deposits are going to accumulate, and this is what causes the dreaded drop into limp mode and check engine light and fault codes on so many vehicles.
My 2005 Toyota Rav4, has suffered the problem on and off for some months. Since adding a full bottle to half tank (the guidelines say add two bottles to a full tank) and after the first 100 miles, there has been an incredible difference in the throttle response. The turbo kick is now very noticeable. It feels like a new car.
If you are ever told that you need a new Turbo/And or EGR valve, try this product first. It could save you thousands of pounds!
A fantastic product!!
