ZP-518 Diesel Injector Cleaner

What To Expect: ZP-518 Diesel Fuel Injector Cleaner contains Vacclaisocryptene, an intense pressure sub-surface lubricant that penetrates the metal 3-4 mils. It will easily go through gum, varnish and carbon. The engine’s horsepower, idling, emissions, and fuel efficiency will improve after one application. Cylinder head compression will increase. Some engines that have not had the benefit of a regular maintenance program have shown an even larger increase in compression. To determine this, note compression before application and again after use.
