912 uls when I hit idle on a hot days especially it drops to 18 lbs and 36 at cruise. It has always done this since I owned the plane but I get a warning every time. Should I do anything?

    I believe the oil pressure range to be 12 - 36 psi (warm oil)

    Assuming your gauge to be reasonably accurate (looks to be the case) your oil pressure is within the recommended operating range.

    Your "warning" system may need to be adjusted so as to reflect the recommendations.

    You may just need to install a new sensor. Those readings are pretty low even though they are in range. I would put a mechanical gauge in line at the sensor port and check it against your panel readings. Pressure senders are the cause for bad readings a lot of the time. It's fairly rare that a Rotax has a actual low oil pressure. I've replaced many a VDO sender. If it's mounted on the engine at the oil pump it can be remote mounted to help reduce vibration issues.
