I did my first one at about 500 miles. That's an old habit I've been nursing for a long time. After that, it's been every 5000 for me with quality oil (mostly Pennzoil Platinum) and an upsized OEM Toyota filter.

DAMN!
That is EXTREME overkill.
Can't hurt, so why not!

Right, but...
That stuff hits the filter during the first 100 miles. Washing out the oil at 500 miles has NO measurable benefit.

PHATBLK, yes, the stuff you can see is mostly in the filter in the first hundred miles or so. When a motor is breaking in it is doing two things. 1) Heat cycling the parts and 2) All of the metal surfaces are seating. As all of us that pay attention to gas mileage and performance know, mileage goes up and performance increases for about the first 5000 miles. This process is definitely heavily weighted to the first few hundred miles but does continue for a while.
So why, exactly, does this happen? It is the metallic parts seating against each other and reducing the friction inside the motor. During this process, microscopic metallic particles become suspended in the oil. The filter gets the larger ones but the really tiny (single digit micron sized) particles pass through. This can be verified in a lab with an oil particulate analysis test. So do you want that stuff in your motor until the first 5000 miles are up? I dont. Will it have a "measurable benefit"? I dont care :) To each his own though. If I was pinching pennies, I would probably wait. I am fortunate enough to be able to spend the extra cash. Just a few less lattes :doh: |

I hear you...
But I am comfortable with following manufacturers guidelines on this one.
Maybe I will change the oil at 3000 miles (just to be a little edgy).
