Hello, I'm new to the forum. I want to start out by saying this is a very interesting and informing forum. Now my question pertains to the issue of manufacturers denying warranty claims on their engine work because the owner used something other than an OEM filter and did their own oil changes. I don't know if this has ever happened before. But I have a 2004 Honda Civic that i want to do my own oil changes on, and I don't want to use OEM Honda oil filters since they are made by Honeywell the parent company of Fram. Even though Honda has the filters made to their specs. they still have Fram characteristics like cardboard endaps. For that reason I would like to use either Napa, Purolator, Mobil 1, or some other more reputable company instead. So has any dealer ever denied your claim because of this reason? (p.s. sorry for the long post.)
