valve seat recession

The Fuelstar product is without peer for its ability to enable engines designed for leaded petrol to operate on unleaded petrol without loss of power, without pinking and detonation and without fear of the engine suffering from valve seat recession.

In more than 100,000 installations worldwide (in cars designed for leaded petrol), there has not been one single report of valve seat recession by any motorist using Fuelstar.

Not only that, but in hundreds of cases where VSR was being experienced (as evidenced by the need to frequently adjust tappet clearances) the incidence of VSR was actually arrested immediately upon installation of the Fuelstar product.

Of course, this is totally contradictory to the findings of the New Zealand Automobile Association. But then one has to bear in mind that their test was conducted with the Fuelstar left laying on the floor when it should have been bolted to the engine, as specified in our published installation instruction. In the words of world famous scientist Dr Jim Sprott "if a test result is at odds with results achieved in actual usage in thousands of cases over a lengthy period, it is the test result or test methodology which should be regarded as suspect, not the product being tested."
