oil level fluctuations after topping up

parabmw · 03-17-2015, 05:37 PM

On a long trip oil level indicated lowest bar. To add 1 quart.
I add half quart. I day later it indicates oil at top bar.

Would a long drive affect how much oil the sensor picks up?

No it shouldn't. Sensor could be lose , are need to be replaced

I have noticed mine sometimes did that when parking on inclines/etc.

The oil expands as it gets hot and will increase the oil read level.

Possibly bad sensor!

Bad sensor or car was not fully warmed up when second reading was taken, esp if car has an oil cooler and t-stat had not opened yet.
