I manage an O'Reilly store here in MO and got some promo info from Valvoline on Thursday. It seems that as of May 28, they will offer up to a 300,000 mile engine warranty if you change your oil regularly using Valvoline. I haven't studied the info in detail yet, but your car must have under 75K on the odo and the engine is guaranteed up to 150K if you use conventional oil, up to 225K if you use a syn blend and up to 300K if you use Syn Power. I visited their website and the details will be available on the 28th. I'm not trying to shill for V, just wanted to let y'all know.
