Nobody can tout an oil without doing used oil analysis on their own vehicle. Promoting this viscosity or that or this brand or that means nothing more than uniformed opinion and not science. Thinner oils recommended by manufactures were engineered to perform in those engines by oil engineers - so you think you know better? Thicker is not necessarily better, especially when the newer engines have closer bearing clearances. Just try to get a high viscosity oil into a close tolerance bearing surface on a cold January morning. See how much harder it is for the engine to just turn over with thick oil in the crankcase on a cold morning. You may think that the higher pressure on the oil gauge when cold is doing the job when in fact it's flowing over the by-pass valve and not getting into the bearings, it may even be by-passing the oil filter. Pressure is a measurment of resistance to flow, not better lubrication. I've tried Amsoil and Redline and paying the extra money for those oils has not proven out in my used oil analysis. Right now I use
synthetic 0w oils as they flow better on start-up and lubricate great as well, based on the wear metals in my analysis reports. Oil pressure does not separate bearing surfaces, the engineered characteristics of the oil is what keeps the oil lubricating. Vehicles have oil pressure gauges to show flow because a flow gauge would be too expensive to use. But when you see higher pressure on the gauge it is just telling you that the resistance to flow is higher, not that oil is getting to the bearings, we just assume it is.
By the way, if you think you're confused now just go on the BOBISTHEOILGUY forum and see how all the "experts" can't agree, you'll really start to loose sleep worrying about your oil.
