I bought a floor jack, and it didn't raise the car very far. Unloaded it goes a lot higher, about twice as high to the spec. Figure the oil is low. Can I add something like straight mineral oil sold as a laxative, so I don't have to buy a bunch of jack oil? That should be pure mineral oil. It probably doesn't need much. I can see oil through the fill hole if I tilt the jack, so any additives would be in that. I was thinking of adding some 3 in 1 type oil. Good thing there wasn't much in the can.
I read that you should just cover the piston when filling, to not overfill.
