I guess if my car runs and drives I don't need to check the oil following that thought? lolTry it out. If it lifts what you want, use it.

Double-checked the manual for mine and I guess I read it too quickly.... It does say before using it to "check the oil level" and "fill it to 1/4" below opening". That's just making sure there's enough in it, not that they ship it empty though. I do remember reading that and thinking "a 1/4" from the top of the opening or the bottom of the opening (where the threads stop)?". I bought a small bottle of "jack oil" at the same time anyway.
I have about .7L of AeroShell 41 fluid left over from changing out the fluid on a set of Tektro bike brakes and topping off the hydraulic convertible assembly on a bucket Chrysler Sebring. Will that work for a jack too?Jack oil is hydraulic fluid AW32, ISO32 or SAE10. Some people run a little thicker just because they want to. Some people run thinner if they work in cold climates.
Although ANY fluid will make the jack function, if you’re trying to make the internal seals last longer/prevent rust, avoid brake fluid, motor oil, or water. I’m unsure about ATF, although I know a number of experienced folks that say they use it with no long term ill effects. Most jacks will have polyurethane, nitrile (Buna-N), nylon or leather seals, look for a fluid compatible with those materials.
I’m unfamiliar with AeroShell 41. I went to google. It says it is an ISO 15 which should be fine. It also says compatible with “synthetic rubbers”, not “natural rubber” which is good but I didn’t bother to go digging deeper to see if anything specified nitrile/buna n or polyurethane (both synthetic seals commonly used in jacks. I doubt you would have leather seals in your jacks unless you have a Weaver, Hein Werner/Lincoln or an older than 1980‘s jack.) How much ocd do you have to go digging on the internet deeper? If you find out, let us know.I have about .7L of AeroShell 41 fluid left over from changing out the fluid on a set of Tektro bike brakes and topping off the hydraulic convertible assembly on a bucket Chrysler Sebring.
