Re: shock Fluid
I have a can of Fidelity Shock absorber Fluid manufactured in 1937. The weight is approximately 10 to 20 weight. This is an estimate, but it's clearly not as light as ATF and, from what I see, not as heavy as 30 weight oil. I would have thought it would be heavier. I would have thought that the jack oil would have been a good replace too. I can't say how much it's changed since 1937.
