I didn’t add more oil as worried about overfilling. Now, I will check oil level after driving in garage and it will be varying between 1/2 low and 3/4 low from time to time. Now it’s bouncing between low oil indication and 1/4 low. I’ve read in posts that the oil sensor can’t really fail but perhaps the connectors are getting corroded. I’m thinking I may replace it regardless just to check it off, change oil and starting paying attention to how much oil I’m adding and at what mileage.
Sorry I can’t help - looking for similar advice.

You may be in the same boat as me here, but one piece of advice that I’ve gathered from reading different posts, is that you shouldn’t put more oil in until it tells you to. Like if it’s half way to max, leave it until it gets to the last bar. Not sure why, maybe there was an explanation but I saw quite a few people saying this.
