Valve Saver Fluid that works

NO valve wear after 10.000 km test!

For a 10,000 km field test of JLM Valve Saver fuel additive a Peugeot 107 with an LPG liquid phase injection system was used. First the vehicle was first driven 12,500 km without a protective additive and the valve clearance was checked. During this unprotected period 6.10 +-2μm/1,000 km was the average valve recession on the exhaust valves.

For engine optimisation for liquefied petroleum gas, the geometric compression ratio in the test vehicle was increased from 10.5:1 to 12:1. As a result of these measures, the wear on the valves will be equal or superior in comparison to the pre-determined reference value.

The additive was added by the JLM lubrication system. The specified consumption of the additive is 1ml Valve Saver fluid per one litre LPG. According to the JLM product information, this value will be achieved by setting the dosimeter to 12 drips per minute in engine idle mode.

The valve clearance was inspected during the test, at 0km, 2445km, 5886km and 10249km. There were slight differences in valve clearance in a range of up to 10μm, which matches the resolution of 10 μm of measuring equipment, but these were 0μm on average. Based on the initial observed wear, the estimated valve wear without any additive would be 61 μm for 10,000km and should be reliably identified by the measuring equipment used.

The last final valve clearance inspection was conducted at 10249 km. The measured average valve recession was -0.4 μm/1,000 km over the entire test distance. With an accuracy of +/- 1μm/1,000km in mind the road test can be interpreted as a confirmation that the fuel additive basically stops the wear of the exhaust valves.
