When we hear “new,” we think of products that are crisp and fresh—like a car just off the lot or a laptop computer still in the box. But that’s not what your new oil or machines are like. One of the most common misconceptions in maintenance and reliability is that the new oil we buy is clean enough for immediate use. 

From the point of delivery to each subsequent lubricant transfer, the ISO code potentially increases by at least one grade — the equivalent to doubling, and in some cases tripling, the amount of contaminant in the oil.
