This is very difficult to generalize, when the two bodies are in sliding contact, due to friction there generates wear (of the softer material). If the oil is highly viscous in nature, the wear debris will not flush out and eventually cause more wear (by acting as abrasive particles). Also at the same time frictional heat is generated. This will eventually lead to degradation of the vegetable oil (this depends on the melting point of the oil).
In general, as you keep on increasing RPM, if the vegetable oil is not behaving as a good lubricant, you will always see increase in wear rate.
Hello Sir,
I agree with Mr. Saxena. It is very difficult to genealize. Their are many properties of the lubricant which can influence wear.
I would choose some parameters, for example the viscosity of your oil (for example [1]) and compare the influence on wear with other data. This could help for the first step.

The most important factor is the geometry of the contacting sufaces and resulting film thickness. If the geometry of the contacting surfaces promotes a wedge then, with sufficient rpm will you will get a hydrodynamic effect and very little wear since you have full surface separation. Most systems start and stop so most of the wear will occur at startup when RPM is low and the pressure effect of the wedge is at a minimum. The Stribeck Curve describes this relationship for journal bearings.
