Hi Eabmex

With a glow, the moment and duration of ignition of fuel is not controled.
When there is compression, ignition starts and temperature in cylinder increases.
So oil is used not only to lubrifiate but also to refresh. That what is oil is about 20 or 22 %.
With Electronic Spark, ignition is at the good moment. So oil is only used to lubrifiate.
15 to 17 % methanol replaces oil and gives to engine more power.

Regards

Sorry for my bad english
