Use of excessively oily fuel-oil mixtures was required back in the day, when basic mineral base 2T oils were all that was commonly available, and added oil compensated for the relatively poor performance of the oils then available.
However today with vastly superior fully synthetic oils being easily available, there is certainly no need to mix at the type of ratios required for old style mineral oils, and as much of the intake charge on a 2T motor goes straight out of the exhaust port, excessive amounts of oil will quickly clog the exhaust system and reduce performance.
Finally using excessive amounts of oil will not damage a 2T motor, but will mean that the combustion process is less efficient, exhaust ducts get clogged much more quickly, and bikes will simply not run as well as using the correct amount of oil.[/QUOTE]
Personally I would not drastically reduce oil ratio in Villiers engines (particularly 2 & 4T) musc below manufactureres spec. I personally use 24 to 1 in my 4T. As for carbon formation, with modern mineral 2 stroke oils there is not the carbon build of as with older oils. I have doneseveral 1000 miles & carbon build up in ports is neglegable. Remember oils is cheaper than bearings (and oil seals) and a de-carb if needed) on a 2 stroke is a straight forward process. I use Comma 2 Stroke mineral oil.
