R;
Good point!!
I 'preached' that when I managed Service Stations in the 50s & owned one in the 60s. Customers that wanted a special oil; I sold them @ 'case lot' and got the service labor.
Next time I'm at the Airport I'll ask around & see. There is an answer to the oil issue.
Many of the failures were from 'sub-standard' lifers also and that is part of the equation here too.
Probably the answer is a combination of both; A) finding an aircraft or industrial/commercial oil and B) getting someone to Mfg. lifters with a harder/more durable face here in the USA.
Perhaps there's a 'harding process' that could developed also.
Happy trails.
