Most lubricants, food grade or not, are based on mineral or synthetic oils of specific viscosities. To be more specific, there are two ways viscosity can be viewed: kinematic viscosity or dynamic viscosity. High performing suspension oils sometimes have Vis in the range 300-400. Using a thicker oil to stop oil leaks can work sometimes, but it can create other more serious problems you never thought about. Engine designers specify a certain oil viscosity for a reason and its based on bearing clearances, engine cooling needs, oil pump capacity, fuel pump needs, and valve timing mechanisms. These are the current methods for calculating the VI for petroleum products used in civil and military applications. Standard practice for viscosity index (VI) calculation as per ASTM D2270 and ISO 2909. As an example: 30W oil flows much faster at higher temperatures.. Air with dynamic viscosity 0.018.

The higher the You are trying to make 20W-50 oil I guess. Kinematic viscosity 2. mm 2 /s. The actual operating viscosity, , of the lubricant can be determined from the ISO viscosity grade of the oil, or the grease base oil, and the operating temperature of the bearing ().You can determine the rated viscosity, 1, from diagram 2, using the bearing mean diameter, d m = 0,5 (d + D) [mm], and the rotational speed of the bearing, n [r/min]. To determine the viscosity index of an oil, we must know the viscosity of the oil at both 40C and 100C. Viscosity rating is a measure of the oils resistance to flow or thickness, and is the single most important characteristic of hydraulic oil. Dan and Davis in 1929 introduced a term, viscosity index to compare the oils temperature-viscosity relationships in relative to each other. Rubia TIR 9900 FE 5W-30; High Viscosity Index.
