The Royal Purple was changed at 5-6,000 mile intervals.
The Mobil 1 was changed at 4-5,000 mile intervals.
Sorry, I was going by the 3,000 miles you put in your original post. Was that just the number of miles on the car?
I read it as he swapped over to RP when the car had 3k miles on it.

Edge vs. Mobil 1 aren't complete bull.
That was in regard to 5w30, this is 5w20.
Yea I know, I was just trying to screw w/ the Mobil 1 guys. But isn't it safe to assume that if one weight of the oil is performing much better than another brand then the other weights would perform comparably?
Not necessarily. M1 0w40 is nothing like its brethren for example.
