Hey everyone! I have a ton of old oil cans. It's what I've started collecting. I was wondering how do you can tell the age of the can. I know some cans have dates but for instance I have three DuPont zerex cans with no date.




Thanks!

welcome to Oldgas.. the earlier cans were first made in '33-'34 with a soldered seam. Then came the crimped
seam cans followed by the composite cans.. cool

some people like them full & some drain them- IMO that has little bearing on the value of the can. I don't drain them unless they are leaking, its true that a full can hitting the ground is going to have a little more damage than a empty one.. cool

All are Crimp closure.
Early have crimp on inside & are soldered out side.
Next was the Crimp inside w/ Solder in crimp to seal.
Next was Outside Crimp w/ Thin Rubber in crimp to seal.
Last was the welded Seam.

Thousands of Green FALCON qts were found un-filled & w/o lids. For awhile they almost couldn't give them away, but prices are on the rise now.

Here's some info that is a little about dating cans and some extra info also - bet I picked up the info her on OLDGAS...

Oil can date'ing

In July 1926 the Society Of Automotive Engineers (S.A.E.) crankcase oil viscosity numbers were adopted. (ie. SAE 30)
By late 1933 Winter oils were classified in accordance to their viscosities @ winter temperatures, these are marked without the SAE but with a 'W' . (ei. 20-W ) Multi -Grades were available by 1957 ( ei . SAE 10 W 30)

The second system of motor oil classifications was established for the petroleum industry by The American Petroleum Institute (API ).This system classifies oil by types according to the design and operating conditions of the engines in which the oil is to be used.The first types were REGULAR,PREMIUM and HEAVY DUTY.In 1952 API replaced these types with:

ML - light duty

MM - medium duty

MS - severe duty

DG - severe (diesel)

DS - extremely severe (diesel)

DM - severe(diesel) was added by 1957 ( DG now becomes NOT severe)

Some oils are designed for both gasoline and diesel service and may be identified "FOR SERVICE MS - DG (1958)

Summing up::
SAE
1926: SAE30, -40 etc.
1933: 20W (SAE winter oils)
1957: Multi grade oil start.

API
???? - 1952: Regular, Premium, Heavy Duty
1952: ML, MM, MS, DG, DS,
1957 : DM severe diesel, DG - NOT severe.
1958: MS-DG oil for both gas and diesel.

I'm surprised someone isn't pointing out that a couple of books have been written about cans.

I believe they are still available.
