And if we compare the 3 oils in the table below .....how is not MOTUL sport the best out of those 3? I cannot understand? People keep mentioning 10W30 5W50 10W50 but I'm not talking about that I wont use anything other than 5W30 5W40 or 0W40.....I'm talking about the best 5W40 oil with the best noack and HTHS....maybe I'm too stupid to understand? Or are you trying to tell me that as long as the oil meets the minimum HTHS and noack there is no point comparing those characteristics, and I should be looking at something else to determine the best oil for my application? Subaru turbo boxer engines are notorious for shearing oil even under normal driving conditions....that's why i'm looking at HTHS and noack...
