I just got my oil changed @ 300 miles (worried about little metal shavings circulating thru the engine) and they put in 3100 Motul. It's a synthetic blend and I'm not sure if I'm happy about it. They insisted it was the right thing, but I question it because when I asked after the fact they said "You're done with your break-in period, right?" and I barked "NO!!! I said I'm still breaking it in!" Of course they said that it was that right oil in that case. Do any of you know for sure? They seemed like a bunch of knuckleheads.
