I cant find anything in the manual.Does the manual give a specification - Mil-spec or SAE? A buddy that used to race them told me the easiest front suspension upgrade for a MGB is to replace the spec. shock absorber oil with STP Oil Treatment. It's a rather thick mineral oil, possibly too thick. MSG
I’ve spoke to a guy up in Paris TN who restores big guns for some time now. He said he uses a mixture of transmission and hydraulic fluid. When he gets to his shop, he’s going to get me the rations.I have used the light grade of hydraulic oil. I am unsure what my seals are made of, leather or rubber, and if hydraulic oil will hurt them but it has worked so far.
