Bought me a newish Chevy truck. It's going to be used as a daily driver which will includetowing and hauling often. I'm going to use Quaker state fully syn and want to use a good filter that won't cost me an ARM and leg to buy like the amsoil,royal purple and k&n which I like. I was thinking purolator one or fram extended guard both get good reviews and sell for under 10dollers. Any opinions on the two or advice on any others would help. Oh BTW I want to do 6k oci.
