Synthetic oil will not cause a leak, but it will find an exsisting leak better than regular oil. Newer synthetic oils from the last ten years will not harm your seals, this was the original synthetic type oils like " mobil 1" when it first came out. Even Hemmings puts out a synthetic oil for old cars. Synthetic oil will get their faster on start ups, and is superior to keeping the wear down over time. Dom Domenic

I have used Castrol 20W-50 for many years. An alternative is Sh*ll Rotella. It is designed for diesel use, and has high zinc content. Many, if not most, oil additives usually grease bucks out of your wallet. Synthetic oil isn't recommended by our shop. It is very good for modern engines, but tends to leak in old ones. Non synthetic oils are less expensive so frequent changes in lightly driven vehicles are a better choice IMHO.

I agree with TomO and 42 Merc. Most over the counter oils will work just fine in a flathead. Today's oils are far superior to the oils of 40 or 50 years ago. This oil question has been bantered around for years and it still comes down to just using a good grade of over the counter oil from your local parts store or discount store.

It's been said and is true that the cheapest oil available today is better than the best oil in the 1930s and 40s.

Tom is right on with his take on oil use for our flatheads. Stock & mildly modified flatheads are very happy with an average over the counter motor oil. Extra ZDDP & $7.00 a quart oils are a waste of money in our world.

IMHO after market oil additives are not a good idea. The major oil companies do extensive testing on the oil and formulate it to reduce wear under extreme conditions. The additive companies just test their additive to make sure that it does what they claim with a generic oil. It may do nothing with certain brands of oil, it may reduce wear with other brands of oil or it may cause damage with other brands of oil. The ZDDP scare is just like the unleaded gas scare. High performance engines may need special oils, but most main stream engines will get along fine with a major brand of oil. The biggest promoters of these products are the ones that have them to sell. The 32-53 Ford engine are not stressed enough to warrant adding ZDDP to the oil. A Ferrari or a Porche racing engine could possibly need the extra protection. Some of the horror stories about engines being destroyed in a few miles are either fiction or the engines were not repaired properly and the mechanic needed an excuse. Finally if you have doubts about whether you oil is protecting you engine, send a sample of your used oil to be analyzed. If your oil does not have enough wear protection, the analysis will show excessive amounts of metal in the sample. Here is a link to an article on oil analysis. http://auto.howstuffworks.com/how-to-do-engine-oil-analysis.htm

This is the company that was making that other stuff they use, to use to clean out the motors. Can't believe the guy said he's been using it for ten years , and I never seen or heard about it, it sounds great! thank you very much I am going to try it. Happy New year! Dom

Add a bottle of this stuff when you change your oil to put your mind at ease > https://rislone.com/product/3x-concentrated-engine-oil-supplement-with-zinc-treatment/ "The clinging properties hold the oil to metal parts preventing wear and dry starts. Special additives also prevent oil thinning at high temperatures where normal oil fails. The ZDDP creates the sacrificial (disposable) layer on any component where metal to metal contact happens preventing the metal itself from being worn away. This high performance formula stabilizes the motor oil to insure against viscosity and thermal breakdown. It also reduces friction and wear, especially at start-up, helping to eliminate dry starts. Less friction means less wear and a cooler-running, longer lasting engine."

Well, a roller cam and lifters will have less friction. Whether it is worth the effort and expense is another question I am nowhere near qualified to answer. I suspect someone has dyno tested a 289 with different levels of modifications, so the data should be out there somewhere.

Rislone is a product that the old timers told me about. They said every other oil change or so they put a quart of this stuff in with the oil and run it for 500 miles and then change the oil. This was back when oil had no detergent and would badly sledge up. I wonder if you only run your car 500-1000 miles a year and if you don't sit their and excessively idle and add unspent fuel into your oil, and change your oil every two years how dirty will non detergent oil get? Can you even buy non detergent oil anymore?
