I just put the 20W-50 Castrol in mine last Friday before my Moab trip. Outside temperature in the morning was 18° and it started up fine. Gave me a little more oil pressure than the 10W-40 I replaced.

I have been using 20W-50 oil for years, usually Castrol brand. Deprnding on your climate, it is a bit heavy for other than summer driving.

Suggest considering a multi-grade oil spec'd for gasoline and diesel engines. I've found it in 15-40 and 20-50. Been using WalMart's "Super Tech" 20-50: best price I could find. Happy New Year! Roger J.

The only place to put non detergent oil is in your oil can, not your engine. Contrary to the myth about causing deposits to clog the system, it keeps contaminents in suspension until they can be filtered. If you don't have a filter, just shorten your drain periods. We do use a special break in oil in our rebuilds. It contains ZDDP (zinc)to assist in the initial operation, aiding high pressure direct contact metal parts, such as camshafts, to resist metal flaking. After the first 500 miles, it isn't required. Avoid full synthetic oils in old engines, as the primitive seals usually can't prevent leakage.

The main benefit of detergent oil is not to clean sludge that may already be in the engine, but to keep the sludge from developing in the first place. It does that by suspending the sludge producing particles in the oil to drain out with the oil rather than settling on the bottom of the oil pan or sticking to metal parts. It looks darker and dirtier because it's doing it's job. If you want cleaner looking oil that lets the pollutants just accumulate on the bottom of the engine and metal parts, go for non-detergent. But, it's an illusion. That "clean" oil is creating a dirty engine. Read more here: http://www.ehow.com/about_6761438_detergent-vs_-non_detergent-motor-oil.html

The most important thing to remember about motor oil today is first, get a good quality oil, and second, get a multi-grade oil. The Multi-Grade oils will lubricate your engine properly at the cold start, while a single grade will not. I don't think non detergent oil is available in multi grade. If that's not enough to convince you to use non detergent, then know that despite the sky is falling rants about detergent oil breaking sludge away to clog oil passages, nobody has ever experienced that phenomenon from simply changing from one type to the other. Know also that some will tell you to use oil additives, in particular to use a zinc additive, which will change nothing but the thickness of your wallet. Zinc additives are needed for some high compression engines, but certainly not your stock 1936 Ford engine. Save your money otherwise spent on additives, and put it toward frequent oil changes and you'll be much better off. Alan

I was told by a couple of old pro's to use non-detergent in my stock 36. I just bought it and I'm not sure what the previous owner might have used.

Non-detergent oil is readily available in most auto part stores such as NAPA or AutoZone. Just look for the words "Non-Detergent" on the container. Just curious. Why are you wanting to use non-detergent oil?
