Leave it on.
And yes you can use oil filters for more than one oil change, my father always changed the oil filter on his engines every 2nd oil change, that would mean he changed the oil every 5000-6000 miles, and the oil filter every 10000-12000 miles, using conventional oil and motorcraft oil filters, and he never had a problem, and this is not using modern high quality conventional oils, but rather 70s and 80s oils.

Absolutely agree with Bronc...leave the filter alone.

If it makes you feel any better at all, my last two work vehicles were 2014 Subarus...and Outback and a Forester. Both engines were the brand new FB25 NA 4 cyl boxer engines. The engines are notorious for burning oil though mine never used more than 1 qt in 15k.

My maintenance plan was simple...I ran Mobil 1 EP with a Fram Ultra filter to 15000 miles. Drained the oil, left the filter and ran another 15000 miles. My filter saw an honest 30000 miles. At each 30000 mile interval I would change the oil, oil filter, and air filter.

This was all done with UOA verification that I was getting proper service from the oil and filter...my UOAs looked great. I was driving about 60000 a year at the time and did not have a single issue with either vehicle with the exception of the $8000 dollar CVT failures at around 140k. My wear metals were far below average and my filtration was always stellar.

I maintain my brother in laws car and I do the same...except in his case I run conventional 5w20 to 5k and change the oil and air filter every 20..again with a farm ultra.

I loosen the filer, then re-tighten. Many vehicles today are designed so the filter sits in a manner where half of it's contents will depart. Also a number of vehicles exist today that are designed with oil channels that sit right above the top of the filter threads. These oil channels will empty also.

So in most cases today, no need to remove the old filter, then re-tighten it. Just loosen it half-way, then tighten it.

Also, I don't oil my filter gasket, when I initially install it new. I use Gorilla Grease on the gasket and there's no need to apply anything more to the gasket, when re-tightening it. That particular grease is like an anti-seize lubricant. So it eases removal.
Sounds like a recipe to make a mess and get contaminants into the system/seal. If I went thought the trouble to mess with it I'd simply change it.


What trouble? What mess? I never said I had to relube the gasket either.
What's so hard about holding a small drip kitchen pan under the filter, to catch a few ounces?

Please explain why it's a mess? Hurry thou! I'm getting dizzy thinking of your wrong answer.

Leave the filter on. For most filters, you're talking about less than 1/2 quart of old oil left in the filter, and for some even less than 8 oz.

More than that will usually be left behind in a normal oil change where you change the filter, stuck in the oil galleries and oil pan. The overall impact on the refilled oil will be minimal.

If you remove the filter and then re-mount it, you're potentially likely to introduce contaminants and/or cause a gasket leak, which, IMHO, is much worse than leaving a cup or two of old (and perfectly serviceable) oil in the engine.

For almost every vehicle on the road, the filter gets covered with oil as soon as the seal is broken. Topside canisters are even worse...YMMV

Yes, I do. About a cup runs out. I then fill it with new.

Why do you say this? I've been doing this for over 25 years. I have NEVER had one leak.

As an aircraft mechanic, I always cut open used oil filters (Most A&P's do).
I started running oil filters every 3-4 oil changes in the early 90's after repeatedly cutting multiple oil filters open and never finding any significant debris in them.

This sounds ideal. In my experience, I see no issues at all with this scenario.

I always remove the filter and let the oil out...wipe the flange on the block clean and re install...the gasket on any oil filter is very robust and does not leak or wear out...

I also remove and drain the filter, then reuse it. It gets a new filter every other oil change. I have never had one leak.

You answered your question better than I can. It's a few ounces of oil. It's not worth going through any trouble. You do what you like. It's not going to make a difference either way.

Revised after I left ... Prior to 2013 filters were every other time. And that was from my first exposure in the 1960's to my last project with them in 2013.

I'll dig for that article on retained oil. I lost track of it. may take a day or so...

i leave the filter on and dont touch it.. I don't like the dry starts or the chance the filter gasket could become damaged.

Personally, I think the seal is the weakest part of the spin on oil filter. Have read about and seen with my own eyes seals sticking to oil filter housings even though they were oiled with fresh oil. Those seals get baked, and start getting hard just like nitrile ADBV do. I change the filter every time just because of this very reason, and I think it's a valid reason.
