I have been reading that some filter can do 15k, and get more efficient in that time. However 15k is at least twice the OCI that I want to do.

If I choose to reuse a filter, should I at least unscrew it and drain the old oil out?

On both my vehicles, the filter mounts mouth-up, and probably has at least 1/4 quart of oil in it. I'd like to get rid of that oil if it is advisable.

I wouldn't recommend it, Id be worried the gasket wouldn't make a good seal the second time around. If you can get replacement gaskets for your size filter, AND get the filter off without denting/damaging it, i would say go for it.

Personally.. Id just switch the filter out every time, and use a cheaper filter.

don't unscrew. You're more likely to mess something up with the seal.

There's also more than another 1/4quart of oil hiding around in the other galleys and parts of your engine.

Plus, if the oil is so "bad" then you've already been using "bad" oil in your car for the last portion of your interval. You should be changing the oil before it gets that bad.

True: It will be more efficient as it traps more dirt...but only to a point though and then it becomes restrictive. You could remove the oil filter and drain it but I wouldn't.

5 dollars or the hassle of spilling oil everywhere...

And a filter always gets more efficient the more clogged up it becomes, just switch to a cheaper filter if you are that concerned about saving money.

If it is easy to get to, I choose to drain the oil out of the filter mount. I have never had an issue getting the filter sealed back on properly. That is just the way I do it.

If you drain it you will be giving it another "dry start". If you going to do that, you might as well just use a new filter.

Seals are made for single use, single compression. One time. You are risking your engine.

A new filter every 7500 miles is not exactly wasteful. Id rather have clean oil and a new filter than worry about the negligable increase in efficiency of reusing an old one.

Metallic seals, yes. The soft metal used (aluminum) will work harden.

Elastomer seals... no. Most types eventually harden, but a few compressions hwile they are still flexible won't age them significantly.

1/4 quart? Usually more than that. My wife's Civic owners manual says a 4.4 quart total capacity with 3.2 quarts change w/o a new filter and 3.4 quarts change with a new filter. Apparently there's a lot of space in that engine for the oil to hide, even with a tiny overall capacity.

I vote no because I don't want to break the seal.

New filter every oil change for me. This is like the guys who pull spark plugs to look them and reinstall. The labor to remove means new part put back on for me be it an oil filter or spark plug.

That's the way I feel. Some filters hold close to a qt. of oil like my E-150. That's almost 1 qt. of dirty oil mixing with the oil that doesn't come out of the engine because of the design. That could be 20% or more of dirty oil mixing in with fresh clean oil as soon as I turn the key. I'd rather just change the oil and the filter and call it a day. Obviously opinions vary, that's mine FWIW.

That's a 0.2 qt delta, which is essentially 1/4 quart. grin
