This is a quote from the above link.....
I was recommended by the person who did my engine, to use
10W-40, due to the Crane roller cam/lifters and Yella Terra roller rockers.
The reason......Need a thinner oil (10W) on cold start up to penetrate the roller bearings.
I can't tell you how many times I have heard someone, usually an auto mechanic, say that they wouldn't use a 5W-30 motor oil because it is, "Too thin." Then they may use a 10W-30 or SAE 30 motor oil. At engine operating temperatures these oils are the same. The only time the 5W-30 oil is "thin" is at cold start up conditions where you need it to be "thin."
