A straight weight dino oil foams less and gives up the bubbles more readily. A straight weight synthetic even less with a bigger margin in film strength and even bigger margin to overheating.

The use of muli-grade oils is at fault for some foaming. A straight wei= ght=20 dino oil foams less and gives up the bubbles more readily. A straight weight= =20 synthetic even less with a bigger margin in film strength and even bigger ma= rgin=20 to overheating.
 
I use 40 Wt. RedLine racing oil. There are others.
