A couple weeks ago, our technical specialists Rick Paulino and Gordon Stack measured different brands and types of olive oil. The two technical specialists tested to see if there was a difference between 100% pure olive oil compared to olive oil that has been blended with 10% canola oils. Their study concluded there was a ~10 cP difference between the oils, with olive oil boasting a higher viscous characteristic.

As a lubricant begins to breakdown it undergoes significant viscosity changes. These viscosity changes can play a critical role in the life and performance of moving parts. For example, knowing when to change the engine oil in a car is straightforward, every 3,000 to 5,000 miles is a good rule of thumb. Going beyond the recommended scheduled oil change runs the risk of critical component failure leading to engine damage. However, what if you don’t have a convenient method, like miles driven, to gauge the health of your lubricant? How will you know when the lubricant begins to breakdown? The solution to this is knowing your viscosity!

Valvoline has recently launched a pressure-activated cobalt grease that can protect engine parts from damage especially in high temperature environments. The purpose of the grease is to provide a continuous film between moving parts under pressure. Normally under high temperature, the friction between moving parts and the lubricant reduces the viscosity of the film, potentially resulting in metal-to-metal contact. Valvoline’s cobalt grease employs a lithium sulfonate complex thickening system that is effective in dissipating heat and preventing corrosion in extreme conditions.
