Not likely, assuming one uses a little common sense.
Question for those who reuse oil filters
- Thread starter himemsys
- Start date
When I used an oil filter for multiple OCI"s (only on my Hondas, per owners manual) I would leave it on. If you remove it you may as well put a new one on, as gasket deformation and damage may occur. As of late I have replaced the filter with each OCI as OCI's are now very close to 1 year.
Until the oil breaks down and smokes an engine, lol.
As a master oil change tech, u poke hole in can to get old out to recycle it, try it crazy how much oil come out !! So this whole post is a joke, better to over change filter VS oil..............
Well do what you are comfortable with but Honda has have DI and oil dilution problems. I'd change it all out! Get a reading on your fuel dilution!

I do not remove it to drain it. I leave it on and make sure to use the same oil for the second OCI.
For me, using the filter twice on cars that say it can be done is simply a time saver. Sure it’s only a few minutes, but that’s a few minutes saved to do other things…

So you're saying running oil for 50,000 miles is just fine and it won't cause any problem?
Loosening the filter defeats the purpose of using a filter for a second oil change. No time is saved, it still makes a mess, and it could potentially leak.
As for the second part of your comment, I’ll pass.
Yes. Many don’t realize there’s a lot more than what the filter holds still inside the engine. Coating parts, sitting in the pan, inside the pump etc.

On a oil forum and don't even understand oil oxidization above ^

Do you guys pour in a quart of new oil with the drain plug open to make sure and purge all that oxidized oil out of the pan too? 
Na I use a quality oil flush like 95% of all professionals except here on BITOG. So, more oxidized oil in the circuit is better than less?Do you guys pour in a quart of new oil with the drain plug open to make sure and purge all that oxidized oil out of the pan too?
But why would you use a flush just to dilute out oxidized oil? Now you have leftover flush to flush out.
Flush doesn't hurt anything at low levels and burns off anyway. We have seen UOA's here on BITOG that verify only minute differences in viscosity with an oil flush.
Sure, but if your goal is to get the bad oxidized oil out then it would be more efficient to use new motor oil. The flush isn't going to un-oxidize the leftover oil somehow. This is a simple dilution.
Yes exactly, that's why hot oil and the flush will bring more out because of dilution and chemicals to remove more contaminants, deposits etc.
Uh okay.
Well look thick oil isn't going to drain as well as thin it will cling to more internals etc.
Even then one OCI in bypass isn't going to blow up your motor. However-bypass is very unlikely to happen.
