For oil gear pf h2

hello my friend
i want your advice about changing the oil gear of my h2, it is 250k km and may about 150k km has not changed
the oil looks like need to be changed
the guy Technichen told me he will suck 3 bottles and add new 3 one but he said he will not give me any guarantee if something happens to the gears
but he said it is better than changing the whole oil one time
should I change the oil or not and just keep it as its ?

Also I noticed the oil pressure is high do you think it is ok to be between 60-80 at stop condition!?

That seems to be a very high idle pressure to me but if no one has changed the oil in 150,000 km I cannot imagine things are in good condition internally and the oil filter is probably 100% clogged up.

is it easy to replace the oil pressure
and this gauge is it related to the oil engine or related to gear oil ?

I mean replace the oil filter

Do you mean oil filter this one ?
i have change it with also the oil engine and still pressure high ?!

By the way, i notice the pressure gauge is at 40 psi when the car is not running but just the key is plugged us the below picture
do you think it just the gauge is just broken?

Not really sure. The gauge is for the engine oil. The engine oil filter should always be changed when the engine oil is changed. How long between really depends on the specific oil you use and your driving habits. Even with the newer extended interval synthetics I'd never recommend more than about 10,000 miles (or whatever that is in km).

Yes it is possible the gauge itself has a problem but a gauge problem usually has different effects like randomly not working at all. I'd have to go out and check on mine to be sure but I'm pretty sure with the ignition on, but the engine not started that RPM, speed, and oil pressure should all be at zero. Battery will show current charge and if the vehicle has been run recently the temperature gauges will show the current temps and the fuel gauge should show the current fuel level.

In your first post you are talking about gears though. So I assume you are talking about transfer case, a differential, or transmission. On those I've always just changed them in full when due, not partially.
