most syn oils are full of additive packages that make them heavy duty. And thats where the problem can start...
The additives can super clean the engine... and if the gaskets are bad but goopped up, the additives will clean them and then you will have leaks everywhere from the old pourus cork gaskets. Also syn oils will react with silicon gaskets as discovered and documented by cummings... And cause them to break down and leak. The cleaning can cause clumps of sludge to break loose and then stop up oil ports if the engine is badly goopped up with sludge. In one case I know of, the owner had a toyota sludge engine and the hd oils cleaned it but the screen on the oil pump would slowly clog up and he had to pull the pan every two to three months when the oil pressure dropped off. He eventually got the engine clean enough from the hd oils that it quit doing it. Pulled the pan 4 times before it finally quit clogging the screen.
Also on very old engines at a idle, the syn oil flows with much less resistance and therefore lower oil pressure, so if there is a lot of wear, the oil pressure light will be on when at idle. Not a problem but scary to the user as you cant tell low pressure from no pressure.
And if you have a really old engine with poured babbit bearings, the new additive packages will actually scrub out the bearing material... but you woulld have to have a pretty old engine to have that problem....
If the engine is clean of sludge, gaskets are good, synthetic oil or even an hd group 3 oil will be fine.

I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the
