Hey guys.

Quick update that my Blackstone analysis didn't show any abnormal wear. In fact the oil looked great. So, I'm pretty sure the Motul 5W-40, which is actually more like a 0W-40, is just too thin when running a high ethanol mix & boost tune.

Altho, they did say that my silicon levels were a little high and pointed to not good enough air filtration. I had put in the aFe dry drop in filter when I changed the oil last, so back to the stock air filter!

I put Redline Euro 5W-40 in this time, so we'll see how the burn goes since it's thicker like a typical 5W-40. Its viscosities are similar to the Motul 10W-40 I used previously (which is a thin 10W-40) and didn't have any burn. Time will tell.
