Oil Change
 

Stupid question, but I just changed my oil. I put 6 qts in, forgetting that there's a 5.5 qt requirement. Would I be best to drain excess oil out of the engine, or am I safe to drive with the full 6qts in the car?

Thanks in advance!

no issues with 6 quarts.

Probably not, 6qts should be still okay, as long as it's not overflowing, check your engine oil metering stick.

No overflow, was mildly concerned but no drivability issues so I guess I can assume its safe.

I would not exceed the limit. Too much oil can cause foaming effect and that is pretty bad for the motor.

If you're only over a bit (I think the spec is 5.8 with a filter change), and it bothers you at all, just grab another filter and change it. That should be roughly the right amount of oil to remove. Re-start the car, shut it off, and wait for a few minutes to check the oil (these engines seem to take a bit of time to drain back into the pan). You'll probably find that it is just a hair under the "full". Perfect.

Pulling that filter off is going to be a mess.

Easiest solution. Draining half a quart is tediously difficult compared to switching a filter, especially on a Subaru.

It is extremely important to run the oil level no higher than maximum on the dipstick.

Once the crank starts hitting the oil surface you will have problems.
