Engine oil again

[nkaminar]

I don't mean to start another discussion about engine oil, but just to relay some information.

Here is what Terry Burtz says about engine oil in his "Builders Guide."

"As a minimum, we recommend that 10W-40 or 20w-50 motor oil be
used both for break-in and thereafter. Better oil is available like Mobil 1
15w-50 (< $25 for 5 qts. at Walmart) or you can use 10w-60 full
synthetic which is even better."
