Oil Level Indicator Drops When Engine Idles

[sgriffith]

I have a 2002 LX470 and when I am in park & the engine is idling, the oil level gauge will drop to almost nothing. Then, if I rev the engine a little, the gauge will come back up. Does this happen to everyone? Yes, the oil level is just fine in the vehicle.....that was the first thing I checked. Thanks in advance for the suggestions.

Mine idles at about 1/2 gauge. Rev = increased oil pressure = higher guage reading.

Idling at next to nothing? I dunno, could just be the sensor, but I am not a professed technical genius of this truck.

Of course I've got an LX-450, but mine runs a little below half way under idleing conditions, and a little above 3/4 under load.

I'd check your owners manual for the proper operating range for the guage while idle and accelerating, but dropping to the bottom line seems low.

I would check the sensor and make sure the engine is not coated in sludge blocking proper readings.

The gauge is oil pressure and oil pressure changes depending on the RPM's.

Check oil level with your dipstick. The behavior seems normal, you might ask Lexus to confirm.

It is dependent on rpms to increase pressure but if there is a blockage it will drop lower than normal and only be partially open when at higher rpm's.

As already mentioned the oil level is fine.

That is the normal activity for the oil pressure gauge on Toyota motors. No worries.
