straight8pontiac Posted June 3, 2012 Share Posted June 3, 2012 What would be the proper fluid or oil used on the front shock absorbers of a 1937 Pontiac? Thanks in advance for any help.Dave. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted June 3, 2012 Share Posted June 3, 2012 (edited) It's called "Knee Action Fluid". GM dealers and parts stores used to sell it. Nearest substitute is hydraulic jack oil or motorcycle fork oil. Most guys just use the jack oil. If you really want knee action fluid, there may be some vintage oil companies that still make it.Kanter products has "Delco shock oil" @ $12 for an 11 ounce can (ouch!)

Guest bofusmosby Posted June 4, 2012 Share Posted June 4, 2012 Rusty, can these "subs" be used along with what's left of the original oil, or will the shocks have to be drained first of the original fluid? Link to comment Share on other sites More sharing options...
Rusty_OToole Posted June 5, 2012 Share Posted June 5, 2012 If there is a drain plug you might want to drain out the old oil as it is most likely dirty and nasty. But there is no harm in mixing the oil if that is what you mean. Link to comment Share on other sites More sharing options...
