Instead of looking at failure rates lets look at rate of bad bearing inspections. You dont want to run the engine till a rod kicks out the oil pan, right. I have yet to see ANY bearings come out from people that have actually had the pan off that looked satisfactory. From what a few of us that know what we are looking at will tell everyone every rod bearing that has been changed is on its way out due to oil starvation. Every bearing looks the same.
Although cold start is only around 2% or so of the total running time remember that 90% of all wear comes from that 2%. In terms of oil temp, 210 is not hot, every single car on the road that uses a 195 thermostat runs at least 210-220 on the oil. The only way it can run cooler is to have a external oil cooler of which most cars do not have. The cars on track that run 250 on the oil, that is fine too. Oils are so good now that 300+ is when you want to start watching pressure data.
The 0-40 is one of the highest quality oil you can buy. If the weight does not work for a certain situation then that is fine but for the porsche guys to say it is lower quality than something else is a false statement. The 5-50's on the market fall back to a 40 rather quick anyway just as the tws falls to a 40 over its life. I have tested some bottles of tws when it tests brand new at a 50 and not a 60. It is more like a 53-54 from factory tolerance. dont confuse protection factor with viscosity it can be two different things. The reason many love the 0-40 is it is one of the few blends on the market that are a true synthetic. A few redlines, royal purple and the 0-40 along with a few select others are true synthetics.
