If you are having problems with oil pressure, using thinner oil will make them worse. You want to use a heavier weight oil to try to resolve this issue. 20W50 would be the heaviest oil I would put in this engine. However, this is only a patch, there is likely another issue that needs to be worked out. I'm not sure what your conversation was earlier about this, but if you need help figuring out the root of the problem, I can help with that. You can try thicker oil and see if that solves your issue.
