Low oil pressure after a 20km drive?

Hi,

As the oil heats up, it things a bit. That could be the cause if there is excessive play in the engine bearings. That is a possibility with the number of miles on it.

Here is what I suggest. We need to confirm if it is an electrical issue or if the engine is actually low on pressure. What you need to do is get a mechanical oil pressure gauge and screw it in where the electric one is now.

Do this when the engine is cold and then allow the engine to reach operating temperature to a point where it would turn on the light. See what the pressure is at that point.

I attached the manufacturer's oil pressure specifications below. If you don't have an oil pressure gauge, often times a parts store will lend one to you.

Let me know what you find.

Take care,

Joe

Hi,

So, the vehicle can run all day and not have a pressure issue, but if you drive it, that is when it occurs. Is that correct?

If that is the case, we need to check the pressure with a mechanical gauge. I suggest that because what is happening doesn't make sense unless the engine is overheating when driving only.

Is that something you feel comfortable performing?

Let me know.
