    Awesome report. Surprised they recommend trying 12k intervals. FYI your personal information is visible on that form. I would black that out and re-upload it.

    While I Believe the Science behind all this - its still will not make me want to use those suggested OCIs - but hey that is me and my my money so who really cares - I have too many vehicles and can only manage to drive each about 5-6K a year so I change my oils every 4K and again I do not care that it could be longer - maybe its good lawnmower oil LOL.

    Continued Luck and enjoy the Yota.

    I agree 100%. I would change my oil at least annually, regardless of mileage.
