Traditionally, the suggested S O S sampling intervals have been at each oil change, 250 hours for engines, or every 500 hours for all other compartments. However, when you operate the machine under the following conditions a sampling interval of 250 hours is recommended for all compartments.Application
Studies show that a 500 hour interval between oil samplings is too long for the timely indication of potential failure modes for some applications. These applications have high loads and high temperatures. A 250 hour sampling interval provides more data between oil change intervals. This increases the potential for detecting a potential failure.Determining Optimal Oil Change Intervals
Sampling compartments every 250 hours also provides oil condition/performance information to ascertain the optimal utility of a particular oil. Also, more data points enable close monitoring of component wear rates while obtaining maximum lubrication utility. For detailed information on extending oil change intervals, please consult your Caterpillar dealer.Optimizing Component Life Cycle
An increased sampling frequency also provides better defined data trends from one oil change interval to the next. This enables close monitoring of component life cycle wear patterns to ensure full component life cycle is realized.In summary, the standard S O S oil sampling interval for all engines remains at 250 hours. While 500 hour oil sample intervals remain acceptable for non-engine compartments, they are not necessarily optimal. Under the above conditions, 250 hour oil sampling intervals are recommended.
