A 3-in-1 is a pressurised liquid cleaning system that removes gum and carbon deposits from:
The 3-in-1 solution is added to your engine under the same pressure as fuel is added by the fuel pump, this ensures complete coverage of all areas where the gum and carbon deposits normally occur.
The 3-in-1 service retards the engine from rebuilding these gums and carbon, a by-product of fuel delivery and combustion, and leaves you with a clean engine that will run much more efficiently delivering you:
This system improves on the old fashioned method of just cleaning the injectors. With a 3 in 1 the carbon build up and most importantly the "hard carbon", is removed from these areas, greatly improving the volumetric efficiency and the combustion process.
Can you let the mechanic who attended my job know his chemical fuel injector clean fixed all the problems. Cold start is now like new and fuel economy improved to numbers achieved when new. Thanks. Alan, Subaru Outback
