Let's see if this works:

I read the other How to Post Oil Analysis:
"We prefer that you use a code block because the text remains aligned in the post the way it is typed. You can maintain a used oil analysis history in a text editor like Notepad or Wordpad, then simply paste the text into the code window. To post in a code window simply click on the # symbol in the full reply screen like this:"
but for a technophobe like me, it didn't make too much sense!

Always open to suggestions!

OK, here it is two weekends ago on Miami's South Beach.

Wow. What a car!

Am I 'reading' this right - you only drive these two 60+ year old cars?

As for the results, it impossible to say if they are 'good' - this is just too out of the norm to have trends for.

In Florida, with an engine that 'big and leaky', I'd be inclined to find and use a straight 50-weight of some kind.

I'd say this is pretty typical from a car of that era. Only a 1000 miles in two years would account for the fuel, but then carburetors are not the most efficient fuel metering devices invented by man and manual chokes complicate that. This car need to be driven more (I volunteer!). This really opens a whole new method of nitpicking used oil analysis because you can't really apply too many of the standards we use today onto technology of yesterday. Lead for example. The types of bearing used back then used more lead than they do now. And, if the car has an oil filter at all, it will be less efficient than today's, so you would expect to see more wear material.

Addyguy - no, my daily driver is a 142k miles 2003 Honda Accord. The oldies are weekend fun! As to oil type, if you read Motor Oil 101 on the home page of this site the ideal oil should be 5W/50 if such an oil existed.

Jim Allen - agree, need to be driven more! Yes, triple S.U. carburetors with a cold start feature that dumps gasoline directly into the combustion chamber ahead of the carbs, and a wire gauze oil filter designed only to filter out large chunks!
