Can you measure your oil in I-Drive after driving for ~30 minutes?

Welp looks like Toyota wont conclude the oil consumption test.

They stated to me that they were unable to conclude the oil consumption test as the oil measurement system is failing. So they have opted to replace the oil pump and then have me redo the consumption test yet again.

Funny thing is the oil measurement system doesn't even show precise oil levels instead it just shows MAX MID MIN. I was under the impression that they measured the oil through draining the oil and measuring the difference from when the car was originally filled up and sealed

My experience with this car has really been hindered with all of this.

Make sure they change both these parts, insist on it. Would suck to go back and start again because the sensor is bad too.

Here is a post referring to a TSB

I don’t get why some Supra owners aren’t bothered by the consumption and instead just band aid fix it with thicker oil…

Thicker oil isn’t a band-aid. Its a permanent solution. If the car runs better with thicker oil why not switch to it? Its not a bad thing like people make it out to be.

UPDATE: Looks like my oil pump is failing according to Toyota. Coincidentally I got a low oil light saying to add 2 quarts after driving for 1300miles right before I brought it in.

Toyota is saying that they might need to replace the oil pump before they can complete the oil consumption test. Hopefully this doesn't mean I have to redo the test...

Would this be the error message you received?

Any update? Did your oil pump get replaced?

Oil pump was failing causing oil pressure to be low during oil measurement tests. If anyone else has these issues just know your oil pump is failing.

Toyota replaced my oil pump under warranty and now I can measure my oil level whenever I want which is nice.

My oil consumption test “passed” as Toyota said that when the oil light comes on that says to add 2 quarts it only means technically one quart?? What they did for the consumption test is have me drive for 1100-1200 miles and bring the car in. When I brought it in my oil level was at a minimum and they added one quart and measured with the I drive system and it measured max after adding one quart. At this point they concluded I was within the recommend consumption amount. I am still not sure why the system would say to add 2 quarts when it only really needs 1???

So what’s the final verdict? You’ve been given the Toyota seal of approval?

Measure with a scantool rather than iDrive. You get to see a real sensor value instead of an estimate. Also the warning in iDrive does not come on until you are about 1.5 liters down, ~78mm on the sensor readout.

See this is not true as my raw oil value was at 72mm with the car at 1800rpm before I sent the car in. They said all they did is add one quart of oil and it was back at full again. I really don’t wanna believe them on this but I don’t know what else to do

They had me go on my way and said that my oil consumption is normal according to the Toyota FTS. All of the mechanics that work at these dealerships are at the mercy of the Toyota FTS guy that manages a bunch of service shops within a certain area

I suggest you take a look at this before randomly calling things untrue.

At the end of the day, you can choose to believe the OBD measurement or you can choose to believe the iDrive display which has been inconsistent for you.

What I'm saying is, 78mm is equivalent to 1.5 liters down. That's from measuring the amount of oil that came out of my Supra myself. The point here is, the iDrive bar is only an estimation. I think we are saying the same thing here
