Hello Mr. ******,
We appreciate you taking the time to send us your suspect oil filter. The Product Evaluation Team conducted a series of performance tests to include a pressure test, flow test, and impulse test. The pressure test is conducted by filling the filter with 90 psi of compressed air and submerging it underwater. Flow testing a filter incorporates a stand which measures the pressure drop while installed in a typical lubrication system using heated oil. The final test conducted is the impulse, during which, heated test fluid (also black light responsive) is cycled from 0 to 100 psi once per second, for 1000 cycles.
Unfortunately we were unable to duplicate your concern. The filter met engineering specifications and passed the review without signs of leakage. At the production team’s request, we may forward your filter for additional review.
While we were unable to initially confirm your report, we thank you for choosing FRAM and hope that the customer service experience has met your expectations. If you have any questions about the testing procedures or findings, please feel free to contact us using the information provided below.
Regards,
Product Evaluation Team
