I seriously doubt it! The number one reason cars do that is because the oil level is low and the pump is sucking air, not oil from the pan. Every time it sucks air the needle drops, and when it goes back up it means it's sucking oil again. So check your oil level first...
Also some cars have problems where the tube that goes between the oil pump and bottom of the pan can become either clogged or fall off. If they fall off then the engine will suck air because it isn't in oil at all, or it's only a little bit into the oil. If the tube is clogged then the it sucks a vacuum which is basically the same thing as far as the engine is concerned. I lost a Lexus SUV to a clogged pickup, and it was a known problem with that engine but Lexus knew that they usually clogged after the warranty was up so they didn't tell anyone. A-holes. Last Lexus for me, hope it was worth it guys.
Since Lexus and Toyota share many parts and engines, you may have the exact same engine I did, so look into that!

Oil pressure fluctuates on a Toyota Tacoma?
The oil pressure gauge is going to fluctuate on a Toyota Tacoma or any automobile. The oil pressure is less when the auto is idling and more when the auto is going down the road.
How can you check your oil pressure in a Toyota MR2?
To check the oil pressure in a Toyota MR2, you can use an oil pressure gauge. First, locate the oil pressure sending unit, typically found near the oil filter. Disconnect the electrical connector and remove the sending unit, then install the oil pressure gauge in its place. Start the engine and observe the gauge reading; it should fall within the manufacturer's specified range for normal oil pressure.

What is the difference between normal pressure gauge and differential pressure gauge?

Definition of a compound gauge?
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
How do you calculate gauge pressure in a system?
To calculate gauge pressure in a system, subtract the atmospheric pressure from the absolute pressure within the system. Gauge pressure Absolute pressure - Atmospheric pressure.
Toyota Sequoia Oil level dropped and pressure went to zero Filled oil pressure still reads zero No indications of engine damage How can I determine if there is pressure and car safe to drive to shop?
Remove oil sending unit and replace with a manual gauge to determine actual oil pressure I also have a Sequoia 2002, Toyota dealer fixed mine because this a Toyota recall. Take your SUV to a Toyota dealer near you.
How to convert gauge pressure to absolute pressure?
To convert gauge pressure to absolute pressure, add the atmospheric pressure to the gauge pressure reading. This will give you the total pressure, including the pressure exerted by the atmosphere.
What is the difference between gauge pressure and absolute pressure, and how can one accurately gauge pressure in a system using these two measurements?
Gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure includes atmospheric pressure as a reference point. To accurately gauge pressure in a system, one can use a gauge that measures gauge pressure and then add the atmospheric pressure to get the absolute pressure. This allows for a more precise measurement of the pressure within the system.
Does gauge pressure include atmospheric pressure?
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
