I'm not being pickey at all Chief. It works on some engines and conditions, not on others. The larger the displacement is, the less critical the ratios are for general ''sport'' use. Shrink down to K&B Infant Torpedo .020 or Cox .010 size and it quickly becomes VERY critical.
The oil goes flying all over the combustion space and the plug, and guess what, it will bond to the platinum glow plug element far faster and better than the alcohol will- result fouled or dead glow plugs.
