Proper oil for shovelheads
I have heard from several people that the oil used in shovelheads should be a straight weight oil instead of multi-weight oils such as 20W-50. Reasoning was because shovels use a sump type system and the straight weight oils sink particles so they are lifted up to the oil filter and multi weight oils float particles. Is there any truth to this??

SAE 50 or 20w50 will be fine.

Shovels do better with straight weight dino oils, 60 in the hot months 50 fall and spring. Multi's work but the engines noisier and the hyd. lifters will clatter more and lose lift. Synthetics will bleed like a stuck pig from everywhere, syn. wants out and the old gaskets, o-rings and seals will start weeping within weeks of running it.
Last years of the shovel handle the multis better than the pre 81 bikes if you do go that way. Like another said been running Valvoline 50 or 60 in my shovels 4 decades now.
