    I watch CCN a bit and I assure you that he’s 100% correct about the 5k vs 10k mark. The oil additives break down and cause more wear on the engine. If the oil/additives don’t wear down, why do we replace the fluid at all? Wouldn’t we just replace the filter? How does transmission fluid last so long and oil doesn’t? Contamination and viscosity breakdown are properties of the oil, not the engine.

    The people that designed the engine did not design the oil, and that is a very important detail. Do what the oil manufacturer recommends for the oil, not what the engine manufacturer says to do with the oil. As someone who has worked with oil additives and their application, 5k is my choice. If you plan to sell your Toyota at 80k miles, 10k intervals are probably okay for you.

      Do you have a source or any data systematically collected from a unbiased sample? As far as I am aware of there are no sources on this topic. Just anecdotes and opinions.
