Q: What's the proper way to extend oil drain intervals?

A: We suggest you follow OEM recommendations regarding the recommended oil drain interval for your engines. Results from an oil analysis can help you determine an optimum drain interval based on your fleet's engines, service requirements and other factors.

To illustrate, we had a customer who wanted to extend its drains. We were concerned it was extending too far. We conducted oil analysis for a year to arrive at the optimum drain interval given the climate, the fleet and the extreme service. As a result, the customer was able to extend its oil drain interval by 50 percent, providing a significant cost savings and benefit to the environment.
