In short, when fuel mixes with the lubricant, it reduces the viscosity of the oil, meaning that the viscosity may be too low to create an oil film capable of withstanding heavy loads and speeds in some parts of the engine.This results in friction between the metal surfaces and wear of the parts. The type of interference that occurs when light is reflected from a thin film is dependent upon the wavelength and angle of the incident light, the thickness of the film, the refractive indices of the material on either side of the film, and the index of the film medium. A low oil film strength is like trying to blow a bubble with just one piece of bubble gum. Related: Make sure you are using the right oil, not knowing could cost and engine!

Higher viscosity and thickness translates into higher oil film strength, A lower viscosity and thinness translates into lower film strength. Even a tiny oil slick reduces the amount of oxygen that enters the water. It is decisions like these that can make all the difference when its time for a rebuild, because replacing your whole dirt bike engine is a lot more expensive than a routine rebuild. Over head cam squeezes against the lifters causing oil to shear the oils film. However, the unfortunate by-product of castor is that you get some wax and sludge build-up as well.
