Here are oil specs from a spreadsheet that I developed 10 years ago (file dated 9/1998, close enough for 10 yrs since the data was collected over many months). All of the data came from PDS'. The spreadsheet is sorted by VI. Boy has things changed; I think the standard was SL, GF-3 at the time.

Hope the columns line up, it took quite some time in this editor- two flaws with this environment: the editor and the search.

I have some of that Amoco stuff, but it's even older than 10 years old, it's rated SG. Anyone brave enough to try it?

I was thinking of putting it in my dad's lawn mower.

I noticed that too. What are the benefits of SM??

I was surprised back then how competitive Amoco oils were to the name brands and I could only find it in warehouse stores as if it were a clearance item.

Mobil 1 0w30 back then was very close to today's 5w-20s. Look at its PP and FP, serious PAO!
 
I used to use Amoco oil in my then new 1990 Couger. I used to buy it at Kmart by the case. I only used Amoco two stroke oil in all my yard machines and dirt bikes. I really liked the stuff, I was disgusted when Kmart quick carrying it. It was in white bottles with chrome sticker with blue stripes, I think. Amoco Ultimate Gold.
 
Amoco oils did not only have respectable specs but they were 10 years ahead of their time with fighting sludge; the marketing buzz words of today!

Nice pics, thanks.

Sludge is a new thing?

Haha no thanks. I have some old metal/cardboard cans somewhere if I really cared to break into the old stuff.
 
Does oil age better in cardboard than plastic? Something like bourbon, whiskey or wine in wooden barrels .... ahhh 1984 was a good year for SG/SF 20w-50...

I dont know how it ages and I dont wanna find out honestly. Its all leftover stuff from my dad working at a shop before I was born, so at least 30 years ago.
