Review on Efficient Oil Filtration with Fram Extra Guard PH3675 - 10,000 Mile Change Interval by Michael Baird

Revainrating 5 out of 5

Excellent filter, mileage 10,000 km!

I use this filter once a year on my 2001 Suburban 5.3 LS1 with over 300,000 miles. My work truck, lots of stops and traffic during the HOT Texas heat! I drive to a strict fleet maintenance schedule. I do OCI at 3000-4000 miles so about 3-4 oil changes a year with Mobil 1 or Shell Rotella Gas Truck ALL Synthetic. The great thing about these filters is that you can drain the new oil and refill with new oil with confidence!
