In the 80's when I was cutting, my local husqvarna/stihl dealer sold his own chain oil. One day I was there talking chain talk and wasting the day away when a lorry turned up with his oil delivery. I am talking uk sizes..... a 45gallon drum of ep90, which he would decant into one gallon containers sold as chain oil. This was sold to everyone including what was the forestry commission back then. I used many gallons of the stuff and never had any problems like excessive bar or chain ware and it was very sticky using the finger test, in fact much more than today's dedicated chain oil. I am sure ep90 oil is as good if not better than a lot of chain oils especially the many "no name" brands that seem to have popped up saying they are super tacky. EP90 is a minral gear oil I am not sure on its price these days but maybe worth looking into. It worked fine and used in the harsh forestry environment so if it wasnt any good they wouldnt have used.
