Yeah good video but the Redline makes the engine much much smoother. I switched to Amsoil and honestly thought something was wrong. I'm going back to Redline as esther based and moly makes for a much better ride. In addition Redline has far more anti-wear elements, and slightly fewer detergents, so when added up Redline has more good stuff for your engine. Either way, cheap oil that gets changed frequently is better than a good oil that is changed over an extended time.Amsoil signature series 0W-20 the best. Especially for turbo charged vehicles. Second goes to Pennzoil Ultra Platinum.
