Hey 4seasons, I'm in the same boat with my Evo 8. I got the engine rebuilt and installed by MAP. The "Oil Changes and Intervals" sheet we got is misleading. It is prepared for conventional oil break-in, with change intervals at 50, 500, and 1500. The problem is MAP uses Amsoil Break-In oil for their new engines and what was discussed with me was there's an initial break-in and tune for about 25 miles, an oil change with new Amsoil Break-In oil, and then run it to around 1500 miles, at which point it is recommended by Amsoil to switch to Dominator synthetic oil.
I've read somewhere that Amsoil recommends using Break-In oil for a maximum of 1000 miles. With that, I'm going to run my current Break-In oil (in at 25 miles) up to the 1000 mile mark and then switch to Dominator. I'll get it retuned at that point too.
Then.... I'm going to fuck shit up
