Alrighty, so just wanted to give everyone an update. After close to 400 miles in on the new oil, if not a little more, here's what I noticed.
Compared to the factory fill (Idemitsu on the Crosstrek), the M1 oil seems a little louder upon start up. However, after the engine is warm, it's pretty [censored] quiet.
Oddly enough, I noticed that I have a loss of 1 mpg after switching to AFE. Now this is mostly city miles, but it went from 28.5 mpg to 27.3 mpg.
Now, personally, I wouldn't be surprised if the Idemitsu was loaded with all sorts of additives from the factory that inadvertently boosted the MPG slightly. But, I didn't care to have that oil in for more than 2k because of all the gunk that accumulates (dealer wanted to swap it out at 3k).
After about another 5k-6k, I'm probably going to give Castrol Magnatec a whirl, as the dealer recommends Csstrol here (I know it's all marketing [censored] at the end of the day). I will also look into Pennzoil as well, but it comes down to whatever has a nice rebate going at the time.
