I was talking to a friend who is a service advisor now for Toyota and worked for Ford for many years as well. He was telling me that if you have a motor failure during your warranty time both Ford and Toyota do not accept oil analysis so they will not have your oil tested nor do they care if you had it tested yourself. He said they do care if you had your oil changes though and may or may not request to see your oil change slips or proof of oil change and at what millage. I wonder if the other auto manufactures work the same way? I found this interesting and just thought I would share.
I would think they would want to check it to see if you were running the proper oil weight at leased?
