It seems that we have this Forum all to ourselves. :leghump
I have used both OEM and Amsoil in Rexann but I have been thinking about Carquest/Wix for my next oil change. I'm currently using Amsoil so we don't need to do a oil thread. :ar
I'm way past my warranty and the oil filter used on the ZRX is rather basic. As long as the filter material is well made then any other problems with the filter should be obvious after a visual inspection.
