Well I changed my oil for the first time, 667odo. Hehe it's funny, I was driving back from the auto-parts store, and I realized it was going to be 666 on the odo for my first change!! So I drove around the block to get it to 667, I am rarely superstitious ... but it is a machine and I didn't want to give those gremlins any kind of foot-hold 
Anyway, I used Castrol GTX 5w30 (I want to start getting it coated with Moly). Oh and I am getting more and more irritated with my local dealership :mad: I go in and tell them I want three filters and the drain plug gaskets for my P5. He hands them to me, rings me up .... then under my car after I have the oil drained out and my filter off (btw, it was very easy to remove for me, I guess the Mazda Oil Filter Gorilla was on a smoke break when my engine was going down the line =D ) I notice the filter they sold me was longer! I assume it is the V6 filter (part #G6Y0-14-302A) AARRGH, I know it is not supposed to matter, but looking inside the two of them they looked pretty different, and the longer one the dealer sold me just looked generally 'cheaper'. I am taking the two I have left and exchanging them for the smaller one. I pre-filled the filter put it on, overall the car took 3.5qts.
Well on to the good news! While I was under there I installed my Kartboy shifter bushings, it was cake to install. Drove off the ramps and took it for a spin. Wow, the shifter feels soooo much better! I will probably be ordering a Kartboy Short Shifter next.
My engine just sounded and felt better with the new oil in. And best of all, it had been having a stuttery idle before the oil change. Not anymore, it is rock solid ... I am very happy about that
I think the factory oil is crap! I am glad I got it out of there after break-in. I might change this out again with another batch of Castrol GTX at about 1500 miles to get the smaller filter back on there. Then I will go 3k-5k, then switch over to Mobil1 for 5k change intervals the rest of the way.
