Yes you do it while driving, not neutral or park. Thats why I mentioned the long road trip...


30 minutes is not a random number. Thats how the major oil companies measure and determine the viscosities of their oils.

For example, do you think 5w-30 refers to non-operating temperatures?!


To Mr. Morgan, all I meant by "up and down" is to constantly vary the RPM's through the entire band while driving during the break in period.
