Too Much Oil In Car BMW X5 (F15, F85) (06.2012 - 07.2018)

You need to drain the excess. Do not start with an elevated level, you can drain it at a service center or at home, but you need experience and tools.

For your 2017 BMW X5, if you've accidentally overfilled the oil, here’s what you should know and do:

Should You Drive It or Drain Oil at Home?
Driving with significantly overfilled oil (e.g., about 50% more than recommended) can cause internal engine overpressure, leading to potential issues like leaking gaskets, oil entering the turbocharger and intake, or clogging of the engine breather system.

However, if you have only driven a short distance at low revs after the overfill, serious long-term damage is unlikely. Experts recommend driving carefully and at low RPMs only to the garage for oil draining.

It is generally safer to have the excess oil drained professionally as soon as possible rather than attempting to drain it yourself, unless you have the proper tools and experience.

If you do drain oil at home, ensure you remove the correct amount to bring the level back to the manufacturer’s specification.

Checking for Leaks or Engine Issues
After overfilling, inspect around the engine bay for any signs of oil leaks or weeping seals, especially near gaskets and turbocharger areas.

Look for oil in the intake system or unusual smoke from the exhaust, which could indicate oil burning.

Monitor for any warning lights or unusual engine behavior.

Document the overfill incident with your BMW dealer or service center in case of future warranty or repair claims.

Additional Notes
Overfilling can cause the crankshaft to churn the oil, forming foam, which reduces lubrication efficiency and may cause engine sluggishness or damage over time.

Avoid stressing the engine (e.g., hard acceleration or high RPMs) until the oil level is corrected.

If you notice any persistent warning lights, noises, or performance issues, have the vehicle inspected immediately.

In summary, do not drive extensively with overfilled oil. If you have only driven a short distance, carefully drive to a garage for professional oil draining. Check for leaks and engine issues afterward, and keep a record of the incident. This approach minimizes the risk of damage to your BMW X5’s engine.
