[QUOTE="DILLARD000, post: 1050750, member: 74901"] Even with the "best" oil, I would continue to do Oil+Filter changes every 4kMiles\6Mths, simply because the notorious V6~4.0L~SOHC OilPressurized TimingTensioners tend to loose adequate pressure\tension on the TimingChains as they age; I suspect a large part of this problem is due to oil gum+grit buildup inside the Tensioners. If you do go longer, I still would change the Filter every 6mths, then possibly do a premium Oil change once a year, but no longer than that. I've gotten the habit now for several years, of spraying a little CarbCleaner down the OilDipTube & into the ValveCover OilFill, before an Oil+Filter change; let the engine run idling for 5~10min, then do the Oil+Filter change; logic is this helps clear any varnish+gum+grit from the system.
