I know this is an old subject, I’ve read most of the threads the search engine turns up. I was in a pinch, so I went to our local shop which carries only Morgan fuel, and bought a gallon of Cool Power. Got home and called Morgan on the phone and asked a simple question, “Do you mix your fuel ingredients by weight or by volume?” I was referred to one of their techs, who assured me they mix by volume. Just to be clear, I asked if I have 100ml of Cool Power, will it have 17ml of oil in it? The answer was a definite yes.
This is different from what I believe is the prevailing opinion on this forum, which is that they mix by weight, backed up by some forced evaporation tests. So, … are they lying to me? Have they changed recently? Did I not ask the question properly?
Confused,
Mike
