Installed last November on my 2005 GXP. Don't keep track of mileage anymore. I go 6 mos. or OLM. The OLM was at 42%. Amazed at how clean this is. My engine has always run Chevron Supreme 5w30. This filter was run in some -20 degree wx back in January. I recently replaced the oil sensor and the screen was pristine and reinstalled. This engine is an all aluminum 5.3 that has cylinder deactivation so clean oil is a must. No problems here. Glad I gave up on Purolators and found these.
