<p class="wp-block-paragraph">Introducing glycol into lubricating oils exposes your machines to a powerful and poisonous mixture of chemicals. Unlike other harmful contaminants such as water and dirt, the destructive potential of glycol can progress to massive failure of machine components in a narrow window of time.</p>



<p class="wp-block-paragraph">There could hardly be a more important role for the oil analyst than the routine screening of lubricating oils for the presence of glycol. One large oil analysis laboratory that specializes in heavy-duty fleet equipment deployed in mining and construction reported that glycol was found in 8.6 percent of motor oil samples over a period of years &#8211; about one in 12 samples.</p>

					<description><![CDATA[<p>Dipstick oil analysis may sound a little goofy, but it works. Not to mention it’s also cheap and quick. There’s only one problem - figuring out what the oil on the dipstick really means. No worry. Sit tight for five easy lessons on reading your oil dipstick.</p>
