To my knowlege the EDL and ML70 are Ester based oils

I was under the impression that all synthetics on the europe side of the pond were Esters and the AMEX stuff was PAG

I never mix with Castor these perfectly good oils but sometimes mix the 90% EDL and 10% ML70 but to my knowelege both EDL and ML70 can be mixed with Castor for the less Mechanicaly able modelers who will tune engines way too lean and would probably be better off doing electric if they still need Castor



But if I was using PAG there might be a case to use some Castor as it reputed to need 25% more PAQ to do the same job as Esters so lots of formulas in USA will be ~18% oil where ~15% is PAQ and ~3% is Castor to replace a ~10% Ester formula

That's my reading of the story from studying all the issues so I might be wrong but I mix my own brews and use it on my own engines 4 stroke and 2 stroke get ~10% Esters when run in (~15% while running in )

I am always aiming to use the least possible amount of oil as 10% EDL will mean 90% fuel that burns and less than 10% is possible that's even better

Some guys are even more extreme and use a lot less than 10% Esters no Castors and so far best I can see they seem to doing well on those formulas so later I might try that as well
