Hello, I have a new AA3 with the new K24 engine.

I had liked using Mobil 1 5w40 turbo truck oil in my past 4 cyl Lotus also used mostly on track. Most Lotus track guys used this also.
Amazon.com: Mobil 1 44986 Turbo Diesel Truck 5W-40 Synthetic Motor Oil - 1 Quart (Pack of 6): Automotive


TMI suggested 5w30 Mobil oil but I always thought 40 wt for track mostly 4cyl.

looking for suggestions on oil filter also, currently has a stock blue Honda filter and I see no filter number on it?

I am located in Michigan so I don't get the southern heat or long seasons
