HEAVY DUTY

ENGINE OILS
New oil technologies, used oil analysis, and proper
filtration help optimize oil drain intervals.

[ ENGINE OILS ]

O

il is required to properly lubricate an engine and keep it running smoothly. But, it's not quite
that simple. Engine oil must be able to withstand high temperatures, provide shear and oxidation stability, and protect against aeration. In addition, it must be viscous enough to protect
engine components but have a low enough viscosity to provide adequate fuel economy. And,
the oil must be cleaned - meaning it needs to be filtered and replaced on a regular basis.
There are many variables related to engine oil that can affect an engine's health, but maintenance in the form of regular oil changes (also known as oil drains) is key. How often the oil
needs to be changed has a significant impact on a fleet's maintenance operation, so extending
that interval is essential to maintenance efficiency.

used oil analysis, and filtration technologies
all contribute to extended oil drain intervals.
