I had my engine opened up at 341k to replace the water pump. It looked like a brand new engine inside, no gunk or carbon deposits anywhere to be found. My mechanic couldn't believe it. I love and believe in Amsoil's products; and wouldn't drive a vehicle without them protecting my investment.
Hello i have not installed it yet the truck is stored away in my garage for the winter . The oil change has been done in early November and put away in late November. It will get an other oil change in April with Amsoil oil and filter. Thank you.
Never had an issue with build quality or ability to filter contaminates. Never had an issue with fitment either. I definitely trust these filters to protect my vehicles.
