-3 quarts of SM Formula Shell 5w20 to thin it a bit
-1 pint of SLOB additive to help the FS
Maybe I'm crazy for doing this but have done it many times before with no issues. In the end, it's close enough to 30 weight.....
Wow, that Kendall SAE 40 is ancient since it has Kendall HQ listed in Philadelphia. I'm a big Kendall fan and a former PA guy.
Yeah, it really is ancient, it is the old green stuff, pre-Brad Penn.
