| Why You Should Use Self-Closing Valves |
|
Consider using self-closing valves as the dispensing valves on oil drums that are stored in a horizontal position. A self-closing valve will eliminate the possibility of the dispensing valve being left partially open and draining the entire contents of the drum on the ground or containment pad. (Eric S.

| When the specified concentrations of additives become unbalanced, overall oil quality can be affected. Some additives compete with each other for the same space on a wear surface. If a high concentration of a special anti‑wear agent is suddenly added to the oil, the corrosion inhibitor may become ineffective. The result may only be an increase in corrosion-related problems. |

Question: What are the most common wear modes in machinery?
|
GET THE ANSWER
| Natural gas engines have special requirements that differ from diesel and gasoline engines. This is because the natural gas engine combustion process is affected by the type of fuel. The combustion process burns much more cleanly, and therefore soot levels are very low. Consequently, high detergent additive levels are not generally necessary. The process burns methane type fuel, so fuel dilution is not a problem. However, because of higher combustion temperatures, oil viscosity increases can be a serious concern. |
