Synthetic 10-30 Is a great choice
SuperTech full Synthetic at Walmart is about $18 a gallon and great stuff, IMHO

The best protection will be with 10W-30 diesel formulation (CI-4 or CJ-4). For the moment I'd stay away from CK-4 until it is all up to snuff.

No additional additives unless you are a chemist with a lot of money to burn.

No zink in the oil meeans the potentil is there to wipe out a cam logs nd ruin lifters. Read Richard1s article. I'm running the Royal Purple UPS 10w30. It has zinc and phosphorous already in it.

I run 10w-30 Rotella which is available in a Synthetic Blend, but not full Syn.

Phosphorous and zinc zre both needed in proper concentrations, I believe Zinc added alone presents difficulty.

For my 1966 turbo, I am using Rotella full synthetic 5W40 in blue container found at any Walmart here in Maryland. On the back it states 'Meets API service CK-4, CJ-4, CI-4 PLUS, CI-4 and CH-4'. I assume it still includes some zinc for our lifter/cam lubrication.....

A lot of people like Brad Penn 10w-30 for these cars, I believe it meets all the requirements Richard outlined above. You generally have to order it online however. There is a machine shop near me that carries it.

I have debated for a long time whether to mention this knowing oil threads are tricky business! But I want to share something. I was an active member in the vintage BMW motorcycle circles and owned a 1967 BMW R50/2 until a year ago. Very similar concerns about ZDDP and of course they are running air cooled horizontally opposed engines of a similar vintage. Experts in that area stopped using Rotella several years ago when the formula changed. It isn't the same as it was and the experts there won't use it anymore. Our club paid for oil analysis and it substantiated the concerns. The oil analysis was also used to find a new alternative and it showed Valvoline VR racing oils (for Corvairs that would typically be in 10w 30) had excellent ZDDP and desirable properties. So that is the vintage BMW motorcycle go to option based on analysis. I am sure there are other great options too like Brad Penn etc... but I wanted to share that Rotella is not what it was.

Oils are constantly changing. Sometimes for performance, sometimes for cost. Rotella is certainly better than anything we had in the 60's, and easily available, and plenty sufficient for our needs. Personally I'd choose Chevron over Shell, as in general they put more into most oils I analyze, whereas Shell meets the minimum in most cases.

The problem with many decisions based on analysis of the oil is that used, when there are too many variables that affect it. I can get real good results and make maintenance programs with fleets of 10 to 50 vehicles of the same brand, engine, etc. Then within that group I set the bar and we try for the best practices of the best samples.

BTW: I changed my oil last week (after 18 months/2000 miles) and will be sending it in with the next box of oil samples. But I have my own brand.
