Might I ask what type base oil SX-UP uses (API rating?) and its weight?

Have you tried the search function? It is made up of 4 different ester's. I do not rember for sure the API spec. but I think it is a 40Wt.??
Yes I have tried search. Couldn't find it. Thanks for the info.
Searching DID however, give me the answer to my unasked question as to whether SX-UP is compatible (recommended) with Auto-RX. (Answer: No).
WOW a 50 wt? I wanna use it in a friend's '72 Cutlass with a 350. I wanted to use a 10w-40 so would a pint of 10w-30 to the pint of SX-UP even it out?
I was even tinkering with the thought of a 5w-40. Any thoughts about that weight with this motor?
