Guard Fill



The Guard Fill- Gasoline keeps inlet valves, injection nozzles and combustion chambers free of coke residues, reduces friction in the engine and protects all metal surfaces from corrosion. The Guard Fill additive package reduces gas consumption up to 3 percent and can even reduce engine out emission up to 35%. Humidity and condensed water gets removed and the upper cylinder area is well lubricated and protected. Guard-Fill keeps the engine in good condition during its entire life.

Key functions:
– reduces nozzle contamination
– prevents coke residues
– perfect Anti-Foam properties
– perfect corrosion protection
– elevates the octane level
– protects the fuel system from water and humidity
– improved fuel stability
– compatible with engine and fuel system materials

Benefits in details:

Water reaction

The used test method ASTM D1094 shows, that the Guard Fill –Diesel will not cause problems of water emulsion. The Guard Fill –Diesel has no adverse effect on the water reaction properties of base fuel.

Corrosion protection

Our product also protects against corrosion in wet fuel systems. Tests conducted on our Guard Fill-Petrol treated fuels have shown excellent protection against corrosion even at low treat rates, using the modified ASTM D665/92 method. Without our Guard Fill-Petrol, the test are fails; with Guard Fill-Petrol the test pass with very good result of “A”.

Keep clean effect

In Europe and other parts of the world the accepted test for the measurement of intake va lve deposits is the Mercedes M102E test carried out according to the CEC F-05-A-93 protocol. The test are carried out with European Gasoline’s, conform to EN228, with an IVD requirement of < 25 mg/v. After the test the IVD value are 15.2 and pass this test with very good result in Keep Clean Inlet Valve Deposits. Another test carried out with Asia Pacific 95 RON Gasoline, with an IVD requirement of < 50 mg/v shows a test result of 37.4 mg/v and passed also the test protocol with a very good result in Keep Clean Effect.

Intake valve deposit control

The ASTM D5500 test method use an BMW over a 10,000 mile distance. The Intake Valve Deposit requirement needs to be values below 50 mg/v. The result after the test are 25.3 mg/v. This is only the half of the required value and means a very good deposit control during the complete test period.
Another test with an industry standard Mercedes M102E engine over a 60-hour period shows the following result of inlet valve deposit removal, measured by weight:

– Gasoline without Additive: 285,5 mg/v inlet valve deposit
– Gasoline with Additive: 86,8 mg/v inlet valve deposit.

The test result shows a clean performance (percentage clean-up) of 69.6 %.

Octane number increasing

A special additive component in the Guard Fill-Petrol may raise the ROZ octane number of fuels with lower qualities. Test with different fuels have detected an increas ing of approx. 1 to 2 of octane numbers. The used test method are the EN ISO 5164 standard
