Leaky Floor Jack
This was a $200 (on sale $99) jack, so extremely likely it uses o-ring seals versus u-cups. I have several of the multi-size o-ring kits so there is a chance I would already have a suitably sized replacements . I believe I have two issues, one on the pump piston and another on the ram. Probably both failing O-Rings. Any good resources to point me to before I tear into it? Or better to wait for a sale and just replace it? Thoughts? Getting tired of oil pools and topping it up.

o help on resources, but sounds like it ought to be a fairly simple repair project to replace a couple O rings.

So what oil goes back in my floor jack? What came out looked almost like gear oil - which is not what I was expecting to find.
A quick look at the fluids shelf spotted 5w20, 10w30 and 15w40 motor oil Various gear oils 90w through 80w130 hydraulic oils - "normal" and JD Lo-Vis ATF - Mercon V plus all kinds of other obviously non-suitable stuff from brake fluid through chain oil. With probably 50 gallons of fluids there - almost certain the answer is going to be none of the above

seems stores are running out of quite a few things I suggest you call first if its out of your way. In my case a small cheap floor-jack leaked from day one only used it about 15 times over 15 years. same as the thread about cleaning out the horizontal band-saw gear box. The jack was full of grit, sand, cast-iron filings ...... I changed the ram O-ring to stop the leak but there is quite a bit of wear on the cup piston seal. The issue is a floor jack lays horizontal and any grit that is in the cylinder also lays on the bottom of the cylinder and any grit will saw into the low-side of the cup seal. I would suggest to everyone check the oil Shake their jack around mix-up the oil and then take out the filler cap and check the color of the oil my old oil should have been a light blue and clear. it came out cloudy gray and silver, and about a teaspoon of grit. the STP jack oil is clear and very thin. I'm also thinking if it is a good idea or not, set the floor jack in the vertical position once in a while and cycle the jack thinking it may move any grit, water back into the reservoir. my jack has a filter but the cylinder was full of machining chips.
