Many owners of classic vehicles are concerned and confused by the current debate over what course of action to take. No one seems to know what to do. When 18 out of 22 fuel additives failed in recent independent testing, is this the most relaible choice to make? With the introduction of AV82, even light and vintage aircraft look to suffer.

Firstly, the additional heat of unleaded fuel; and secondly, the effects of work hardening on some seats, in some engines that have given the wrong impression of successes being claimed..

We believe there is only one way to address this controversy and that is the proper way by replacing the original seats - but is that still enough?
