A family member is driving this car and says that a “Check Oil Level” indication comes up and then quickly goes away on the cluster gauge. This has been happening very recently, less than a week. The indication would come on and off so quickly that the driver couldn’t see what the indication was. Today however it stayed on long enough to read it and then went away. Comes on maybe once every 50 miles or so.
I tried to take a level reading on both the engine and transmission via the dipstick, but can’t seem to get an accurate reading. This is after getting up to operating temperature from driving for about 10 minutes, and then going through each gear with the car in park for about 5 seconds, and then completely turning off the car while it is in park. See pictures below. There was no issues that occurred during my test drive. The car shifted fine without hesitation. I wiped off the dipstick and put it back in, but still can’t seem to get accurate readings.
Additionally I scanned for DTCs, and found nothing. Not sure how it works on this car, but I would assume an oil pressure sensor would sense low pressure and set a DTC or check engine light. There’s no indications on the dash.
The maintenance reminder thing says that the engine oil is at 20 % life.
I’ve been doing the maintenance on this car. I’m sure that I have been pouring in the correct amount of oil into both the engine and the transmission and have seen no leaks. I used Acura ATF. This ATF is translucent/blue in color, so I wasn’t able to get an accurate reading last time I did a drain and refill on the dip stick. After getting up to operating temperature from driving around, going through each gear, and turning the car completely off, it looked like there was little to no fluid on the dip stick. Despite there being no visible leaks. Because I knew I poured in the right amount and there was no leaks, I just forgot about it. I drained and refilled twice recently. After the first time I had the same issue, little to no fluid on dipstick, but drain and refill 2k miles later, plenty of fluid came out.
I’m going to lift up the car and check for any evidence of leaks. I had a leaking transmission line at one point so I’ll have to keep this in mind and look for evidence of fresh leaks. I will report back.
Thanks for any advice on how to diagnose this issue.
