It was a dealer screw up. On the receipt I got, it says Installed MZ320106. Which is Mitsubishi brand genuine 0W20 synthetic. Wether they put that or 5W30 in, I'll find out as soon as the service manager replies to me. Probably Monday morning.
I asked my mechanic, who also owns a Evo X, is this any cause for concern. He said no. Its fine. And of course his word inspires confidence. I normally go to him for service but he's 3000 miles away on the other coast.
I can say that after some driving my car feels like its in economy/gas saving/well behaved mode. Again this is from butt dyno "feel". So what do I know?
Thanks again.
It took 15 or so posts to understand what the query was about.
A dealer mix up perhaps. Check with Mitsubishi/Dealer if 0w-20 is fine in your vehicles engine, and get this in writing.
If the oil grade is not correct, then the dealer should provide a free of cost oil change with the correct grade.
Whilst you are talking to the dealer make sure the correct oil filter was used as well otherwise this will need to be changed as well.
