I think every oil passes that spec. Do keep in mind that you have a very rare engine with little to no replacement parts available. Run a good oil,filters and watch the temp gauge like a hawk.
Also it is a valve bender. While the valves will not hit the pistons they can hit each other if the timing belt strips or breaks.
I almost bought one in great shape with a bad headgasket. But ended up walking because it's nearly impossible to find that engine as a replacement. But those 2.4s will blow the head gasket if you sneeze wrong.
