Hi Guys,
What additive do you guys use in your petrol to lubricate and decarbonize your motors. At present use Unleaded Petrol with a shot of morreys Lubricant.
Your views would be appreciated.

I never use additives. Modern day fuels and oils produce very little carbon. The engine lubricating system does a nice job of keeping everything slippery enough and a well built and adjusted carb will keep the mixture from forming excess deposits..
