Thanks Compressor. The product you've found is a highly flammable combustion assister - sprayed into the intake, whereas WD40 is of course sprayed on the ignition components to drive off water and damp. (I think WD40 stands for "Water Dispersant, mix no. 40", and was developed for the space industry).
I can't remember the name of the equivalent combustion assister product in the UK, but clearly remember its use in starting reluctant diesel engines!
