I too like AC delco, purolator, WIX, or anything by champion labs (STP, supertech, advance auto + many private lables are champion labs filters) I've run everything from amsoil, royal purple to mobil one, mobil drive clean & havoline in my rodeo. Currently I'm running carquest auto house brand oil (valvoline) 5w-30 and a carquest filter. In realilty, any low cost oil will do fine by you for 3K mile changes. Havoline is supposed to be one of the best low cost oils of the day. It's your money- & it certainly wont do any harm to your engine, but using synthetic oil & dumping it every 3000 miles is absolutely pointless. If you really want to get crazy with oil & filter info, check out this site:
