Over the last decade or so there have been significant changes with respect to contaminant loading in engines, giving rise to a different approach to engine oil analysis and the interpretation of its ...

A recent study used various gas oils and blends with residual heavy oils in order to evaluate the predictability of four different correlations. The gas oils differed substantially in their ...

The thinner in oil is the easier it pumps through the engine, which leads to a fuel economy improvement. We can all understand that, but there's a lot more to oil viscosity than how thick it is. I ...

Every fleet owner should know the basics about the viscosity of the lubricants they are using and why the viscosity matters. Fleets—especially mixed ones—require a variety of lubricants. This ranges ...

Although oil analysis was initially used for engines as a predictive maintenance tool, it is still a widely used method for guaranteeing the reliability of engine systems. Majority of the mobile ...

Contamination, comingling, mislabeling, and using improper lubricants can all result in equipment performance degradation or failure. Viscosity is the most sensitive physical property of a lubricant.

Experiments using heavy crude oil samples from PetroChina's Shengli oil field show ultrasonic irradiation can reduce viscosity by up to 85%, enhancing oil recovery. Increasing production from the ...
