So far, I like Motul oil. I have burned through Red line 5w30 through 5w40. I ran 5w30 and 10w30 w/o an oil cooler and burned it. I don't have an oil temp gauge but just observing my water temp, it would range between 180-195. I ran an oil cooler with 10w30 and water temps were the same, but I had the oil lines over the manifold pipes. I tried running 5w40 afterwards and I was burning 1.5 qts per fill up and water temps soared to 190-205. I decided to reroute the oil lines under the manifold and switched to Motul 5w40 x-cess. I have gone to 2 fill ups and getting ready for my 3rd fill up of gas, I would guestimate about less than 1/4 quart burned. The car almost feels just as responsive as running Amsoil 5w30 I used to run 4 yrs ago. The car has about 75k miles on the odometer. Perhaps the turbo blanket is making oil temps go up and running a bigger koyo radiator isn't enough. Running an oil cooler with the lines route as far away from the exhaust manifold with the proper oil for your application and driving style is key to stop oil comsumption if you don't exhibit the symptoms of a cracked ringland or leaking turbo seals. I'm curious to know if I can get away with running a 5w30 or perhaps a 0w30? My oil pressure would be lower as well as oil and water temps. A huge balancing act with pressure and temps and heat extraction.
