Anybody out there now what the new engine (cold) 1st start  oil pressure

should be?. When I crank the engine, but not starting it, the oil pressure climbs to 75- 80 psi. Seems kinda high to me, any thoughts?



Thanks

When  I fly, the oil pressure is about 45 psi, Dan. When I start the 

engine and it's cold, it may climb as much as 75-80 psi when the engine 

is cold but, honestly, I don't know what it shows when I crank without 

starting because ... my Jabiru 2200 always starts at the first turn. Is 

your engine new has has never started? Do you have an oil cooler? 

Without the cooler you will see more variation in pressure than with 

it.

Dan,



This also depends upon what viscosity oil you use and

if you have a pressure relief port.  Don't know if the

2200 has one....



My pressure can get as high as 90 psi cold if I use

straight 50 weight oil.  A multi weight oil can reduce

the cold pressure, if it is acceptable for the 2200.



Michel, what weight oil do you use in Norway?

Michael & Kurt



Thanks for the information, My Jabiru 2200 is new, but a few years old. I've not started the engine yet, just cranked it with the starter to 



check things out. I plan to actualy start the engine in two week. The engine has a relief valve as well as a oil cooler. I'm using Shell 



mineral for the engine break in period. Seems from you guys are saying is the cold oil pressure is ok. I'll find out for sure when I actualy 



start the engine. I don't want to fry my nice new engine.

Well, after living in Spain for some years, my favourite is, of course, olive oil but ... oh, you mean, the engine? AeroShell 15W50, Sir! Works well winter as summer!

I understand, Dan. But if your engine was stored all these years with 

the preserving oil from the factory, it shouldn't be a problem and it 

should fire the first time as mine did: on the first spin of the 

starter. About the oil pressure you have, anyway, to put on your check 

list that it is the first item to check when the engine is starter. No 

pressure would require an immediate engine stop. As it will always be 

cooler than operating temperature, the oil will be thicker and pressure 

higher at engine start. It may take several minutes before it starts 

going down. On my engine it won't get over the operating 80°C when 

taxiing. I need to take off to see the "normal" oil temperature and 

pressure.
