I found a case (24) of old Mobil 20-20w motor oil. They are in perfect condition. Is the oil good? Can I use it? What kind of engine uses this oil? Would an old car guy want this oil?

I Can’t Imagine You’d Have Any Use For It. It Was Used When And Where Engine Manufacturers Specified 20-20w. Car Enthusiasts Someplace May Be Interested. CSA

I would for the following and you could too. Unused, you could mix it with a little gasoline, pour into a garden sprayer and give a rust treatment to the rocker panels, rear quarters, door drains, inner outer-fender welds and anywhere else you see access to potential rust areas. Catch drippings on o…

What is the API rating of this oil? SC, SD something like that? It’s suitable for '50’s and '60’s cars used in moderate climates…If its in the old tin cans, “collectors” will buy anything…

Don’t use gas as a mix. Use diesel. Better for the environment. Then spray the rusty bits on the car. The degradation factor of the oil is the issue. Newer oils at any grade last longer due to new mixes. If you have a oil burner you can mix in a pint or so per gallon. I just take my oil to a guy who…

Will diesel work as well to thin the oil for spraying for rust treatent ? Otherwise, will try it. Thanks.

Farmers have been known to spray drain-oil on the equipment that was left outside…But spraying oil on your car in your driveway?? You have got to be kidding… List the oil on E-bay and it will sell like hot-cakes…Does it have the old Socony Vacuum trademark, the Flying Red Horse?

As long as you don’t mind that ‘truck stop smell’…

The post referred to environmentally sound use of unusable oil. I would argue, that if done correctly, it would have a more positive affect on the environment then allowing cars to prematurely age.

Guess you’ve never had a need to do it, no smell after a few days if done correctly.

I think that the owner’s manual on my 1954 Buick called for 20W-20 oil in moderate climates. I know I used this oil in the spring and in the fall. In the summer I used straight 30 weight,and in the winter I used 10W-30. I haven’t owned the 1954 Buick since 1965. My brother does own a 1954 Buick that he restored, but uses modern 10W-30 in the car.
