Nitration is the degradation of oil in the presence of nitrogen compounds. Nitration is a common mode of gas-engine lubricant degradation. It is a particular problem with higher temperature 4-cycle engines. Nitrogen oxides are typically formed during fuel combustion. These nitric oxides react with water to form nitric acid. The formation of nitric acids can lead to a corrosive environment to exposed engine surfaces. Nitration also leads to the formation of deposits and sludge.

   Question: What is the best location for a filter to achieve low-cost dirt removal?

From the book "Lubrication for Industry":

If a lubrication barrier were not in place, moisture in the air would eventually cause oxidation, leading to corrosion. Lubricants cling to the element surface, providing a barrier against moisture. The choice of lubricant type is critical because some lubricants act as a catalyst, trapping moisture droplets and holding them at the element surface, thereby increasing the oxidation and corrosion process.
