I found this on a Google search. Was glad to see it because I had already purchased this oil!
" The BMW MOA (actually, the forum moderator) did a study in which he sent samples of oil to have them analyzed for ZDDP (actually, zinc and phosphorous) levels. That report showed the Castrol GTX 20W-50 having good levels of ZDDP per that study. I don't have the source material, but this was from another Forum. We all know that anything said on a Forum is true |

Welcome to the forum Todd! Always good to hear from another Texan. I hope you know you are awakening a very controversial subject. What kind of equipment are you pouring this wonderful lubricant in?

Source threads:
The punchline is that the higher viscosity oils have higher amounts of zinc and phosphorus because the standards set targets for these and they have different levels at different viscosities.

You might be surprised at what squirting a few ounces of Marvel Mystery Oil into each cylinder and letting it sit a week or so will do.
Rings get stuck in the piston grooves, and the oil rings get clogged and stuck by built up carbon. The Marvel Mystery Oil does wonders with dissolving all that. It won't fix worn out rings or bad bores, but sometimes an old engine smokes because the rings are stuck, and it will help that. As for weight of oil, multi viscosity oils came about when engines no longer had solid lifters. These old flatheads don't need multi viscosity oils. Standard SAE 30 weight is specified, whether you want to be reminded of that or not, but in a worn engine it is okay to run a heavier oil like SAE 40, or add a can or two of STP to your SAE 30 to do the same thing. I would try the Marvel Mystery Oil first.

Thank you for the welcome! I have a 1949 CJ3A, but the info often seems better on the CJ2A site. I also have a 43 GPW that I am doing a frame off restoration on. I plan on doing the same on the CJ3A, but for now it is a driver.
Since I have already opening a can of worms by reviving this post I actually have another question. I replaced my motor oil and the fluid in both differentials yesterday using the advice I found on this thread. Thank you. I am going to replace the transmission oil. I have been having issues finding the correct one locally. My local dealer does have Amsoil Manual Transmission oil. I called Amsoil and the tech said this was a GL4 spec oil and it would not damage the yellow metal. He said they made two types of 75-90 and one was GL5 and would cause issues. This is a synthetic oil. I was going to purchase some today and use this unless there is a reason I should not.

Thanks again for the welcome. I noticed you have a 55 Willy Pickup. I have to say I am a little jealous. I really want a Willy Truck.

Napa GL-1`Mineral oil will work in your transmission, it's usually pretty easy to find. Napa can get it in overnight, $20 a gallon. I think GL4 is OK, as long as it's not a Hypoid oil. I've had the 55 for awhile now, Since the virus came along I managed to get a lot of work done on it.

The Amsoil is if you find it locally, usually it is $18-20/qt. The one I use for my Nissan (also requires GL-4) is Valvoline MTF. I find it at O'Reillys which I know you have down there in TX and it is usually $10/qt. |

The recommended amount for a flat tappet or solid lifter engine.I have 4) 5qt jugs stocked up along with 2) jugs of Break in oil it has 3600ppm of zinc.also made by Lucas. With a completely brand new Cam and valve train I want to be sure it gets broken in properly.

Lucas is a good brand of lubricants, so should be a real good choice.

Morning everyone. Just fired my Dad's early '46 cj2a yesterday here in Waco after sitting since 1974. Found this revived thread very interesting, as I'm definitely on a huge learning curve. Probably be living on this site till I finish the project or run out of money, whichever comes first. Thanks for all the great info!
