Yes, the Amsoil full flow- and by-pass filters are safe to use.
I doubt DC even heard of them, and if they did, I doubt they would have put them on the list.
What do they care about a small oil company that they do not deal with?
Amsoil has a warranty that will cover their filters. You will not have any problems with them.
Besides, even if you use an AC filter, and it fails, DC will still make AC pay for it. On the list or not.
Aftermarket suppliers are responsible for their products.
From what I have read out here, Fram has paid for failed engines.
Besides Fram and the Fleetgard Microglass failing on the 24 valves, has anyone heard of any other filter failing?
