Should they stop using it now because they used it in the 70's ?
Anyway esters make more sense to me than intelligent molecules, so I believe it still contains esters. If somebody has a more up to date spec sheet from Castrol that gives a different chemistry, or says they no longer use esters, then I will happily change my view. Otherwise I will stick with the last know chemistry statement from Castrol about their product.

....
It was stated to have "UMA" technology - Unique Modular Attraction as cornerstone.
Actually the product is a good one - semi-synthetic - and is also available in a "diesel engine" version here in Australia
One of my Sons uses it sucessfully in a highly utilised Japanese turbo-charged 2.5 litre diesel engine

It is a good lubricant with a good reputation
I know what is in it. Not guesswork, not historical PDSs, but actual knowledge. I can't say though, but I am trying my best to correct some assumptions and mis-truths within the bounds of what I can say.
