2001 BMW 325i. I've had an intermitent problem recently with my car running out of gas with the gauge showing about 1/4 tank of gas. It does not occur consistently. This occured yesterday, and I immediately filled the tank. It took 13 gallons, so the gauge was accurate, there were still 3+ gallons in the tank, but I "ran out" of gas. Any suggestions on solutions for this. Thanks in advance for your advice.

Check the resistance reading for the two fuel senders to ensure they are reading the same when the car is on the level. This will determine if one sender is faulty causing an inaccurate fuel reading. Near the bottom of the tank the reading should be about 10 to 20 ohms.

Change the engine oil. I think it is due to that only.
