Germany did not lose the Battle of Britain

It is as I stated, you simply do not just lower the engine oils viscosity when you mix gasoline products in it. Gasoline also acts as a solvent and that includes decreased oil film pressure resistance, like shear stress and tensile stress capabilities. It doesn't reduce wear in the sense that thinned out oil, using gasoline, works as a lower viscosity purpose refined oil, it makes it more fluid. What you do is that you only lower the viscosity but in the same time you alter its characteristics needed for other things besides flow. That's the difference.
