I was thinking a good diesel oil like Rotella and Delo should have enough zinc. Here's link to a thread that has a chart with the amounts of that brands have in their oils. http://www.earlycj5.net/forums/showthread.php?86554-Diesel-oil-Zinc-content

Howdy Y'all,

Oil threads usually turn into "Here's What I Use, and I've Never Had a Problem" and while anecdotal "evidence" might indicate what to use and what not to use, it's not very scientific....

Reading ads from distributors and suppliers that tout a (their own) brand is simply a biased advertisement.

Companies like Comp Cams, Isky and others will tell you what to use for break-in and long term use and you can usually believe them because they're not in the business of selling name brand oils (except maybe cam-lube additives) .....They also don't want to have to warranty their product too often....

It's useful to find articles by people who do not make money from hawking their particular type of "snake-oil".

I like staying informed by reading info from Lubrizol and other industry sites. They're one of few the companies that make those additives that others put their name on from (I hope no one thinks that all the oil companies make their own "secret sauce")

I also found a pretty good article on automotive lubricants at Machinery Lubrication (one of my other favorite sites)..... They don't try to sell you any oil, so it appears that they might be a little LESS biased.

I see lots of responses about the best oil to use, but nothing that would apply to an old "barn find" that has been started and brought back to life. The engine has maybe fifteen minutes on it just to get it started so I can warm up the oil and swap it out. Problem is not knowing whats been in it or what should go in it until I rebuild it and start out fresh.

Any quality API- SN rated oil with 40W or higher in the multi-weight labeling will get the job done while providing adequate wear protection for the older flat tappet camshafts. On an older engine that has set up for awhile, then I’d recommend about two hundred miles on the new oil and then another oil and filter change just to help remove any rust or deposits from the system that may have broken loose within the engine. And insure the engine has a properly operating thermostat so that the oil also comes up to temperature.

Thanks Ted, done.

Also, if you want to use a synthetic, Here's what I found from Mobil

ok. Now that my head is spinning. Is Valvoline good? what weight? I know the book says straight 30w. Or should I go synthetic on just a stock motor?

Sorry to drum all this back up. But there was a sensory overload on all this info.

Play it safe and like Ted says use something with 40w attached to it like 10w40, 15w50 etc.

I've used Valvoline 20/50 and Valvoline VR1 20/50 for about 10000 miles each (20000 total) and it hasn't come flying apart, yet, so I say Valvoline is a good one to choose.

Thank you. I appreciate the quick response for my question. I am just looking for what is readily available on the shelf.
