Yes sir. These people recommending thicker oils are also causing themselves more startup wear. Something that I rarely see discussed.
How about some links to official studies that proves that thicker oil causes more start-up wear. Or is that just parroting misinformation from the 'net.
How about you lose the attitude and look it up yourself. There's plenty of proof out there. Have a nice day.
Just asking for some proof of the claim. As long as you don't do something crazy like use 20W-50 in -25F start-ups, and there's adequate oil flow - ie, the PD oil pump can effectively pump the oil, meaning the correct/appropriate viscosity is used for the ambient temperature - then start-up wear will not be a strong function (if any) of the viscosity.
So if you (or anyone else) can dig up an official study that shows more start-up wear occurs between xW-20, xW-30, xW-40 and xW-50 as a sole function of those different viscosities when appropriately used for their rated ambient temperature, then I'm all ears.
