I am wondering about replacing the damper oil with a lighter weight. Referring to Barney Gaylord’s page <a href="https://mgaguru.com/mgtech/suspensn/fs110.htm">https://mgaguru.com/mgtech/suspensn/fs110.htm</a> the standard weight oil is about 20W or ISO 68 (Peter Caldwell World Wide Imports). Hydraulic jack oil ISO 32 is 10W and fully compatible. I will call World Wide tomorrow for clarification.
