I live in florida now. I have used motul 8100 e-tech 0w40 for some time now, after they changed the formulation on the amsoil euro 5w40. I will be moving to Las Vegas in 2 months. After now noticing how important NOACK is to hi temp climate oils and my car being turbocharged as well. It seems reline blows away motul. I can get redline at dealer price (7 a quart) motul is almost 11 a liter. Which would you guys reccomend? As of now, I don't get over 230 or 240 oil temp. I'm sure it will go up in vegas.
