Michael Patton takes us on the first part of a tour of the Duramax Engine Oil Cooler and its relationship to your engine's long-term health.
Lube Notes: Intro to Lubrication Why Lubricate? Millions, no Billions of dollars are spent annually lubricating every moving part in virtually every machine in operation worldwide. The short answer is that lubrication overcomes friction. Friction is not a complicated phenomenon, but it is important to correctly grasp this simple concept.
6.5 Diesel Suburban Renewal Owners of the GM 6.5L buy their vehicles expecting the benefits of a powerful diesel truck: legendary towing and hauling along with excellent fuel economy — they expect big things from the 6.5. For most however, the 6.5 has fallen frustratingly short in the power – and reliability – department.

Lube NotesIn previous Lube Notes we looked at the role lubricants play in overcoming the effects of friction. In this installment, I want to examine one specialized type of lubricant: grease lube. Looking at previous civilizations, we can see that man has tried several methods to provide basic lubrication to load-bearing surfaces; axles have presented one of the most challenging applications. As far back as 1400 BC, mutton fat and beef tallow were used on chariot axles to reduce friction in order to allow for more speed and to slow down wear. One can only imagine the pressure on the maintenance men to make the chariot go faster and to avoid axles catching on fire from the continuous friction. While there is evidence of lime being added to these fats in order to make their lubricating properties last longer, few other improvements to the composition of grease are known to have been used until we reach the magic year of 1859.
