What you call Microlon, there are several manufacturers of these products NULON or SLICK50
it is quite efficient, it reduces the friction, it reduces wear on cold start and allows not to damage the engine in case of lack of oil
For the oil the extra fluids are advantageous for engine that starts in the cold and small runs, for a camoin that rolls for 12 hours, apart from the start?
the fluidity of the oil depends on the construction of the engine, on a plane we use the 100 + in summer and in winters of 20w 50w aeroshell (engine assembled with important games)

Microlon, that's it: [url]

On aircraft engines, the cylinder piston clearance is indeed very high to avoid tightening during the descent reduced gas (the oil is hot, the pistons remain dilated, but the cylinders cool enormously and therefore tighten, we can moreover, to note the ridiculous compression of these cold engines due to leaks: it is easy to turn the propeller of an engine of 8 liters of displacement with one hand ...
The monograde SAE 100 aviation (very cheap oil) has a hot viscosity equivalent to a multigrade 20w50, type of oil used all year round in many planes in France (not in the ulm who use them auto oils or motorcycle much more powerful)
Modern trucks no longer use 20w50, but 5w30,10w30 or 15w30, so-called "fuel economy" lubricants approved by all major manufacturers such as Mack, Renault, Volvo, MB, Mann, Scania, etc ... [/ url]
