a leading consumer magazine listed this engine as a sludger, and even amsoil recommends (or at least they used to) that you skip the extended OCI and follow the owner's manual. certainly DC added a PCV heater in the 02, but problems continued - although you would not know it from my engine! with the new water pump and timing set, it's good for another easy 100k.
Amsoil SSO - worth every penny, IMHO
