Oil pressure guage bouncing

[Petegraintrain]

What would cause my oil psi guage to bounce between 25 and 30 when idling? Only does it at times not at other times. Oil has to be up to temp for it to do it. Cm570

That information would be helpful to start off with lol. When you say brand new, you mean this is the first start up? A little more info/background would help.

Is the oil temp getting high (over230)? Maybe something wrong with the oil filter? Try putting a new one on it. Did it just start doing this out of the blue or has it done this since hour 1 ?
