Hav been using MV CP 10% 15% 20% fuels since they were out there (and contain a very advanced lube IMO), if one wants to blame something for an unhealthy running engine, they should first blame themselves.

There is nothing wrong with Morgans CoolPower or CoolPower MV.
No I'm not a morgan salesman, Ive used Byron fuels for years before Morgan made it to my LHS. Ive found in my personal experience that Morgans CP all-synth lubed fuel is much more superior to byrons castor/synth & mix or Morgans omega.
