LPG - LIQUID PETROLEUM GAS
CNG - COMPRESSED NATURAL GAS
|
LPG is the low cost fuel of the future. It costs less to buy than petrol and reduces air pollution. LPG is a dry burning fuel and does not contain any wear reducing additives as petrol does. LPG enters the combustion chamber as a gas, has a far higher octane rating (112) and generates higher combustion temperatures adding extra stress to the hot and dry valves and valve seats. The lack of valve lubrication plus the higher combustion temperature of LPG often results in premature failure of exhaust valves due to a phenomenon known as Valve Seat Recession. Then the cylinder head will have to be repaired or replaced. Even hardened valves and valve seats are prone to fail due to corrosion and erosion when driving on LPG. Apart from gradual loss in power, increased fuel consumption and exhaust emission, the repair of a cylinder head is usually a major expenditure, this increases when a broken valve damages a piston or cylinder block.
But what are the hidden costs if a gas converted engine runs without a valve and valve seat lubricant? In a project surveying gas engine users and cylinder head reconditioners it was revealed that the time for valve and valve seat maintenance averaged 25% of the total maintenance and repair time was as high as 75% in some systems. Repair costs of up to AUDS$3,800 have been reported.
Research in USA has shown that even the best valve seats (Stellite) do not prevent valve seat recession when an engine runs on dry gas without a special high temperature valve and valve seat lubricant.

How can you reduce the risk of premature cylinder head failure?
Use Flashlube Valve Saver Fluid, Australias No.1 selling Lead Replacement Additive.
With specially developed upper cylinder lubricants and cleaners most of the foregoing problems are reduced or eliminated. It cleans and controls valve seat deposits, resulting in better valve cooling through the valve seats and reduces exhaust valve overheating due to leakage of hot exhaust gases. The risk of valve sticking is reduced - also a major cause of valve and valve seat burning.
Flashlube Valve Saver Fluid is not an ordinary upper cylinder lubricant/cleaner. It is the first upper cylinder lubricant cleaner in Australia containing a lead substitute, greatly reducing valve seat recession and providing all the lubrication qualities of leaded petrol.
Flashlube Valve Saver Fluid will increase the life of valves and valve seats and reduce component corrosion. The powerful cleaning additives control upper cylinder deposits, reducing the risk of pre ignition caused by hot combustion chamber deposits. The lubricant will maintain the performance and durability of your engine.
Flashlube Valve Saver Fluid is applied to the LPG at a ratio of 1 to 1,000, via the patented and award winning Automatic Lubrication Kit. More than 170,000 Kits have been installed in LPG and Petrol engines across Australia. The flow is fully adjustable and easily observed in the sight glass. All fittings are silver soldered and made from brass and copper. It suits any car, 4WD or truck, is easy to install, fully automatic, and is maintenance free.
The Flashlube Lubrication System has a proven record in Australias toughest outback conditions and has saved motorists thousands of $$$ in unnecessary cylinder head repairs or replacements.
Flashlube Valve Saver Fluid offers excellent protection when using unleaded fuel utilising the very latest oil industry technology. |
