I put a WIX on my first gen Cummins truck before I parked it last season before I stored it for the winter. In the spring, it was running in the driveway when I noticed a huge pile of oil under it. The crimped seam that holds the threaded portion to the canister was leaking like a sieve. I contacted WIX via E-mail looking for a replacement voucher, and they didn't even have the time or courtesy to respond.
