a light hydraulic oil, cannot say exactly what weight grade the oil is, but depending on the brand of closer, will depend on the weight and the color or the scent of the fluid.
the fluid best used in a door closer is an all weather (multi viscosity) fluid, this minimizes the need to adjust the door closer speed as the weather changes.
different brands call theirs a different name,
Norton for instance, they call their's norglide,
LCN they call their oil ultra liquid X

I need a universal door closer 55h5
Only brake fluid can be used for brake fluid. Brake fluid is a glycol-based liquid - it's closer to antifreeze than to oil, but don't use antifreeze in it either. Only brake fluid.
Adjust the length of the arm or move the door closer.
My door slam to hard.
the terminology of door check and door closer are from long ago, in 1880's and 1890's door closers were just a spring device to pull the door shut but not really control the closing speed or force, door check, that was more of a hydraulic or pneumatic cylinder with a piston inside (think of a regular screen door closer, but without the spring) was used together with a door spring to create some controlled door closing, and prevention od door slamming. now, the term of door check is faded because after the rack and pinion hydraulic closer was invented, the dampening effect was added onto the device in the manufacturing process. hence now they are all referred to as door CLOSER. hope this helps, expert in closers here
A hydraulic door closer would be the best choice for a door that is used by children, because it has an adjustable speed that allows you to chose how fast or slow you want the door to close, thus giving adequate time to remove little fingers and hands.

Automatic door closer works with either electricity and/or solar powered gate operators. Depending on your gate automation systems and how they're set up, it can be used as a stand-alone unit or with a combination of other hardware and equipment.

i remember TB but ctb....i would have to say its having to do with the fasteners used for mounting the closer to the door, TB means thru-bolts, these are a long (about 2 and half to almost 3 inches long) bolts with grommet nuts that go through the thickness of door and thickness of closer body, commonly used on metal doors. LCN 4111, that's a handed (hand is indicated by seeing if valve adjusters are in line with the LH or the RH stamped on top of closer body by the arm pivot) size closer that mounts to push side of the door with the EDA arm, (Extra Duty Arm) the last digit of the closer series number, indicates the spring "size" hope this helps, I'm an expert in door closers
no.but it is a lever, the closer you push a door toward the hinges the harder it is to open.
