The Revitalizant is designed to restore, repair and protect against wear the friction parts of fuel pumps and nozzles, all types. After the revitalization process is completed, the piston contact patches obtain high micro hardness properties, which prolong the pump's life-span by several times and protect it from side effects caused by low-quality fuel. Recommendations: The sure sign of revitalizing beginning is improvement in mechanism operation (noise, vibration and smoke exhaust reduction) as early as first kilometers of run. It is necessary to double recommended dose if the wear of the mechanism is high. If after 60-120 miles run mechanism operation improvement does not occur, the most probable cause is a mistaken diagnostics. Application: Step 1: Squeeze out the content of one tube into the fuel tank with a minimal amount of fuel. Step 2: Fill the tank with 10 or 15 gallons of fuel. Step 3: Run the car as normal. Step 4: Revitalization is considered to be completed after 100 hours of mechanism operation (1,870 miles run). For treatment of diesel engines of heavy-loaded cars and other diesel engines with big capacity you should apply the gel for fuel equipment according to the information below: Engine cubic capacity, L: 0-5 L, amount of gel for fuel tank (tube 9 ml) - 1 tube; engine cubic capacity, L: 5-15 L, amount of gel for fuel tank (tube 9 ml) - 2 tubes; engine cubic capacity, L: 15-30 L, amount of gel for fuel tank (tube 9 ml) - 3 tubes; engine cubic capacity, L: 30-75 L, amount of gel for fuel tank (tube 9 ml) - 4 tubes; engine cubic capacity, L: 75-100 L, amount of gel for fuel tank (tube 9 ml) - 5 tubes; engine cubic capacity, L: 100-140 L, amount of gel for fuel tank (tube 9 ml) - 6 tubes; engine cubic capacity, L: 140-175 L, amount of gel for fuel tank (tube 9 ml) - 7 tubes. Note: * Use the gel with fuel corresponding to the season. * Additional (not regular) filtering equipment may reduce the effect of revitalization.
