Change oil filter without changing oil

Is this possible?

I have searched on this and (given that the only word that would be different than any other oil change thread is "without") have found no evidence that you can't change the filter without draining any oil.

I would think that it would be fine since the filter is at the top of the engine compartment, but I really don't want to open the housing and have oil run out all over the place.

You may get a little run but not that much because of gravity and the oil pump is off . Umm, why do you want to do this?

The procedure and ensuing potential mess would be the same with or without oil in the motor - it is all in the pan. You'll get some drip-off as per usual, that's all.

I've heard of some people who change their filter without changing the oil on split intervals with the regular oil changes, especially if they are running very high grade oils. In any case, the OEM filter really can't last the full 15,000 miles so changing AT LEAST the oil filter at "half time" isn't too bad an idea.

a lot of people did exactly what you suggest.

synthetic oil can last a very long time
oil filter can't last as long as the synthetic. It tends to brake/fall apart

Therefore, people who used those super expensive oil (like amsoil) just change their oil filter to get a more "life" out of their oil.

As for me, I change my oil and filter every 7,000 miles.

Thanks for the replies. I am changing the oil and filter every 7500 miles. The problem is that this is the first time I've done it on this car and I believe I received the wrong filter. Of course I didn't notice this until the oil was completely drained from the pan.

Since this just occured this weekend, I'd like to replace only the filter and not waste over 6.5 L of brand new synthetic.

Oh cool, I get it now. Yeah you'll be fine swapping it out when you get the right one.
