Question about Plumbing
The problem is for example, if watering the garden and flushing the water pressure drops below the emergency off pressure PSI. Then I have to manually turn to start to get the water back on. Can the emergency off PSI be adjusted to say 10 PSI? I really want the protection but this switch is useless if I can't lower the emergency off setting.
There are a lot of variables. Are you on a shallow well pump? It sounds like the well doesn't make much water. Check your well tank pressure. With 0 psi of water (drain the pressure) There should be 2 psi of air less than than the start up. If the pump is set to start at 30 psi, there should be 28 psi of air in the tank. It sounds to me like either the tank is shot, or the pump doesn't make much water. If you leave a faucet on while putting air in the tank and air comes out the faucet, then, the bladder is shot.

Don't starve the inlet to the pump. It will detroy it.
Buy a pressure regulating valve and plumb it in line per the instructions. Do not use a relief valve because you will have to have a return line or you will heat the water up on the inlet side of the pump depending on how the pressure washer is set up. It should already have a safety relief valve. You might look and also find a pressure regulator that is adjustable and all you problems will be solved.

Adjust the switch fully in the opposite direction. If you are at 1.5 you are at the light end of the adjustment range of that switch, which can be adjusted up to 5psi. Then let it back off until it works reliably. Rarely do you need to adjust a pressure switch on an above ground pool so it should end up about in the middle of the adjustment scale.

We have to know which engine...
generally, warm, idling engine, oil pressure should read down to 15 psi
Range, normal driving around 40 ~ 60 psi.
High rps will get upwards around 70 or so...
These are general; your readings are low for normal driving.
Oil pump gears are worn, you should replace oil pump .
Other experts .. comment, please...

Wow, it would seem like you have a leak there on the low side. You add and it goes goes back to equal on the low side again. The gauge could be off just a bit. Have you pulled a vacum test on the unit? Sounds like you should pull everything out, vacum and the weigh in the correct charge at this point assuming that you do not have a leak or can find and fix it.

sounds like the bladder tank at the well is ruptured this will cause pressure surge, and pump short cycling, and needs to be replaced asap.
