[QUOTE="TARM, post: 41948, member: 578"] Then ask them what is the actual technical reason for doing that beyound that is what so and so said or what they read etc. Do they have any uoa to support this? The fact is 5w40 15w40 etc once warmed up they all have the same basic vicosity ie SAE.40. Where it does change is with blends or dino oils the large the dif between cold and warm vis takes more viscosity modifiers addtives need to be added. But wih high quailty syn like poa the vicosity range ability of just the base is much greater than with dyno and blends. What you do get with full syn 5w40 is a more consistent oil viscoity thru the entire temp range versus 15w40. You will also notice in most applications with the heui improvement, sometimes only slight, in throttle response. It will be snappier. Also with poa base they tend to resist shearing the best as well. I can only say this applies to high quailty oil. [/QUOTE]
