I wouldn't bother with the dealer. Just start doing your own oil changes. The strap wrench is the best idea. I have one that has proved invaluable. It has about a 2 and 1/2 inch nylon strap that is probably about 12,000 pounds test. It will get off just about any size spin on filter if you can find room to swing a 1/2 inch breaker bar or ratchet. Tapping it off with a chisel on the base plate will work, but getting to it for that is usually a problem. Get the strap; it will probably be the last filter wrench you will ever buy.
