Only one problem, Synthetic. I think most will agree these old engines don't do well on synthetic oils, rear end lube and tranny lube unless they have been built to take it. I know some use it, but when my engine was rebuilt with stock parts and clearances, the builder told me NOT to use synthetic oils, but stick with 10W30 conventional oil. Anyway, your car, your decision.Well I managed to find these two based on c9zx's advice :chin:
5W50 Castrol Edge with Syntec API SN, synthetic
zinc = 1252 ppm
phos = 1197 ppm
ZDDP = 1200 ppm
5W30 Royal Purple XPR synthetic
zinc = 1421 ppm
phos = 1338 ppm
ZDDP = 1300 ppm
Geoff, Search on "synthetic oil myths". I've successfully run synthetic oil in everything (engines, transmissions, differentials, mowers, and yard tools) I own since 1982 without any problems.

Hi SLOk, so it seems I'm getting ganged up against here.
Like anything else, when new technology comes along, there is resistance to it and often for the wrong reasons. Or is it I'm just 'old school'.
I'm am certainly not an engine expert, not even close, so I rely on the expertise of others. In this case that was my engine builder, who is also renowned in my area. His advice was to use conventional 10W30 oil in the 351, so that's what I do. Besides, most of our cars only do around 1500 -3000 miles /year and the oil gets changed every spring, or at least mine does, so why do I need to spend good money on oil that is basically getting wasted?
For my car, I'm sticking with conventional oil.

At the end of the day, it's your car, your choice what you put in it.Hi SLOk, so it seems I'm getting ganged up against here.

Please don't feel ganged up on
I've been looking at all sorts of options -- including conventional lubes with additives
I just guessed these engines wouldn't care for cheap typical humdrum fluids one would put in a Nissan Micra
Has anyone here used Penrite? has any views on that?
Geoff, I'm not trying to gang up on anyone. I'm just attempting to bring facts and empirical data to the conversation. Clearly you can, and should, use whatever oil you desire. However, there are more people in this conversation beside you and I and someone may benefit from what I've stated.

Geoff, same as Chuck in my response, as I guess you are referring to my comment as well. I did my research as well even though my engine builder made the initial suggestion. We ran conventional oil for the engine break in and then switched over. In fact, when it comes to eliminating conventional oil in all my vehicles, I hung on as long as I could with conventional oil use, but now run synthetic in all my vehicles. My mustang's were last to be converted over... I think differing opinions here are good, not meant to be personal, just one's opinion. People will do what they will do in the end...
Ken, It clearly looks like the synthetic side of the fence wins the day. No support from the conventional side!Geoff, I'm not trying to gang up on anyone.
