I don't think you fooled anyone.Gentlemen I've been messing with you. It is Mobil 1 5-30 from the early 80's. It is SF rated and states on the can up to 25k oil changes. It sold for $3.88 a qt. at a discount auto chain in the Washington DC area.
I wish I knew what the base oil was....PAO??
It i interesting to see the lack of additives and the amount of zinc and phos. Didn’t we have cats in the early 80’s?Very interesting…If you go back to April in this section, there is a VOA of Delvac 1 ESP 0W-40, and it has almost the exact same add pack and TBN
When this oil was Esso XD-3; they used to state that the base oil was mostly PAO, and we know early M1 was mostly PAO…makes you wonder if it is the same chemistry at play here - PAO base, and calcium-based detergent pack allows for much longer OCI’s than the TBN would leave you to believe.
I was having some fun with the thinkers on here. No serious expectations. I've never seen an oil like that and wanted to see what others thought. Seems not many were interested anyway.Because out of the hundreds (if not thousands) of reformulations, expecting someone to guess and "speak up" as to what that voa shows is asking too much.
Still interesting on its own merits though.
Got it. Sorry if i came off as pri#k. Lol. Didn't mean to but after re-reading....I was having some fun with the thinkers on here. No serious expectations. I've never seen an oil like that and wanted to see what others thought. Seems not many were interested anyway.
