I was told that Valvoline would be offering a new service to its customers, When using a Valvoline oil Product and using an OCI of 4,000 Miles for every oil change they will warranty your engine for up to 100,000 miles. You just go to their website and put your information in and whatnot. I Don't think it has launched yet but it seems that even DIY'ers can register for it. Anybody else know or have heard anything about this? What are your thoughts on an Oil company giving a warranty on an engine?
