It's a good thing you brought that up cause I didn't know that either.

There are quite a few different theories on break in. However I agree with Jet with the frequent oil change method. The luck I had with mine was using a heavier weight 20w 50. I changed, after first day of running, 500, 1000, 1500, then switched to 10w 30 synthetic and regular routine. Like I said though, alot of different theories are out there, ha ha.

For brand on break in, I have always used rotela 10w30. The properties in it are great for break in. I am suprised no one else has mentioned it yet here.
