I have an old Massey with the same problem. I have gone over to Rotella T5 15w40 oil. Oil pressure is improved and I think the synthetic oil gives better lubrication even at lower pressure. I've been doing this for 3 years...no problem so far.

Is the drop to 5 PSI at idle or up to speed?

And is this something new or any knocking?

If it's always been this way or has very slowly lost pressure over the years, and no new noises or changes in performance it's not really concerning. The rule of thumb is 10 PSI per 1000 RPM is a safe minimum pressure.

But if there has been a sudden change, something is happening. Could be worn bearings, worn pump, stuck relief valve, or oil contaminated with fuel.

One tying that will not fix it is shimming or stretching the relief valve spring.

Run 15-40 diesel oil in it. If you are already, the answer is likely worn crank and maybe cam bearings. It could also be a worn oil pump.

Today's Featured Article - Pop's Tractor of Gold - by Gary Teate. My father was a simple man but could repair just about anythin mechanical that was ever made. From the time I was a young boy growing up in Jacksonville, Florida, I would spend a considerable amount of time helping my father repair or rebuild equipment and engines, etc. on our 2 1/2 acre "spread". Pop always dreamed of having more acreage out in the country where he could retire and tinker as much as he wanted and often reminisced about his boyhood days on his grandfathers farm in Montecello, ...
