Thankyou Alan for a constructive reply.
The whole topic is intriguing although of limited relevance to most on this forum.
The ability of the Lumenition to indicate the range of individual discharges seems a notable feature.
How modern engines give such good mpg without running weak is surprising. As is their immunity to valve damage when some cyls at least must be notably weak.
The unheated units in many applications must spend a lot of time outside the temperature operating range. But were the normal.
I always presumed the energy from the petrol in my Seven went out as exhaust heat as not much reached the road! Or it goes as noise!
