My take on this advice from Tony at KC is that it was probably targeted towards my particular motor and may not be the same advice they would give for other builds. In my case, I have a stock
oil pump, Tony said they set up their clearances a little on the loose side typically, and summer weather was coming on.
Ironically they gave me a case of Joe Gibbs 10W-30 when I picked up the engine and I've run it as much or more so as the 15W-50. Hot, idle pressure in the summer gets down below 20 psi with the 30 weight which is OK, but I like the idea of a bit more. I suspect the heavier
oil may be a good idea to keep my hydraulic lifters pumped up too in hot weather.
