Here are the cartoon instructions on the side of the can. Step #4 says 3/4 turn beyond contact. Now, that seems a bit heavy to me. I don't think I can squeak out 3/4 a turn with oily hands anyway.
Oil Filter Tightening vs Outside Temp vs Engine Temp

I’m sure we’ve all heard it by now, but GM used to indicate 3/4-1 turn. After some leaks they changed it to one full turn. I normally use a cap wrench to get this right.
I guess I am the last guy on the planet to see this memo but I sure have experienced this. My wife's old Yukon had mostly gotten AC Delco filters from Wal Mart since we acquired it. Two oil changes ago I'm struggling to work the band wrench around the filter and I find that just working the wrench in place broke the filter loose.
I chalk it up to my error, but make double sure the new filter goes full 3/4 turn after contact. Last oil change same thing happens again. . After finding finger tight filters twice in a row when that had never happened before in the prior 12 years, I'm suspecting something about the filters has changed. Too scary for me. I'm using a different filter now.
Thankfully it's over 10 years since I had a car with a spin on filter. When I did use them they were always much tighter coming off than they went on. I was a slow learner but eventually put them on quite lightly with nothing like 3/4 of a turn after contact. What I would do is lightly tighten by hand after contact and then make a judgement by trying to back off to see how tight they were. They never leaked. It wouldn't surprise me if the rubber seals were designed to swell on contact with oil such that it would be near impossible to tighten then too lightly.
3/4 of a turn after contact is pretty darn tight . More than I would be comfortable with .

I don’t think I’ve ever gotten 3/4 to 1 turn after tight. At most maybe 1/2 turn. I’ve changed filters in summer, winter, cold and hot engines. I always tighten the same amount, never had one loosen, and always required the use of a wrench to remove them, and never much stress on the wrench (tool). I have had gorilla torque on some dealer served filters that made me wonder why the can wasn’t already split or threads stripped, as they were so tight.
I always tighten as hard as I can with a wet paper towel and one hand then remove with large Channellock pliers. Works for me.

First make sure the o-ring from the old one is still on the old filter and not on the vehicle. That is priority number one. When spinning on the new one the temp doesn't matter, oil the new O-ring then just snug it up with a filter wrench and let it go. When I was first starting out with vehicle maintenance I would put them on so tight you had to stab a screwdriver all the way through just to spin it off.
Honestly, I put a little oil (old or new) on the gasket and the threads, spin it on and tighten as tight as I can get it with one hand. Never had any issues.
Good (and funny) thread. There are probably many right answers, depending on the type of oil filter your vehicle uses.
For cartridge style filters which have a cap that must be removed, you want to follow the torque recommendation on the filter cap. In my case, both of my vehicles have a cartridge style, so the cap gets torqued down until it's "gutentight". I've learned over the years what that feels like and don't need to put the torque wrench on it.
In some cases, especially on the gen3 Ecodiesel 3.0L engines in the Gladiator/Wrangler/RAM 1500, people have followed the torque recommendation on the cap and have ended up with both oil leaks from the cap and low oil pressure warning. That's because the cap gets really tight before it actually bottoms out on the metal lip of the oil filter housing. Advice on the forums is to gently keep snugging it up until it bottoms out, then maybe 1/4 - 1/2 inch past that.
For spin-on filters, I've only ever done hand tight - assuming the mating surfaces are clean and the o-ring is lubed with your finger of choice
I've never had a leak doing it this way, and it always seems to tighten up during the OCI necessitating a strap wrench to remove at the next interval.

If you have a mathematical inclination and a micrometer it is interesting to look up the thread pitch of the filter and measure the gasket height above the can. It is very common for filters to only have 1 turn of compression before the can bottoms out, although right at the gasket there may be a little more room.
My Camry has the plastic cannister. I tighten it until is stops. It stops abruptly. It takes some effort to get it off so I use a 1/2 ratchet with the cap tool. My RAV4 is a disposable can that I tighten by hand and then another 3/4 to full turn with a cap wrench. It comes off with a little effort. I find disposable oil filters very forgiving between just tighten enough to not leak and too tight to get off. There is a wide torque range there.
On my moms Subaru contact + 1 is also the spec. That conveniently aligns with how tight I can get it by hand.
Crank the filter on by hand as far as it will go. If you are experiencing a hard time getting the filter off then...
1)tag a rag and wipe all the oil off the base of the oil filter housing
2)apply a bead of fresh oil on the new oil filter rubber gasket before hand tightening it on
3)don't use a one size fits all oil filter wrench that's too big and slips, go to an auto parts store and find your filter and then walk over to the cup style that fits on an extension/ratchet so it fits like a glove and ya have leverage from the ratchet extension.

Thats a interesting question with the engine being cold? I have no idea except to follow the directions once printed on the side of every oil filter, Place some oil on the O-Ring after it touched, Do 3/4 of a turn but in 45 year of changing my own oil following those same instructions, I have always know to ALWAYS, and Only change the oil with the oil and engine HOT so after it drains and I replace the filter the block has NEVER been Cold?
I guess IF I was in OP's situation I would simply do the 3/4 turn as normal and reach in after its warm and make sure its not loose and never drain the oil cold again, always let it warm up so the oil drains better.

I can usually get a filter on 3/4 turn by hand gripping with paper towel. Last filter I removed was a Fram HP4 racing filter I had to remove with a SnapOn heavy duty oil filter strap. See attached. These get 1 1/4 turned. No more of these for me.

I pull into the driveway of a old friend that he and I go way back to High School days over 45 years of being friends.
This is my buddy out of all my friends that was the "car repair guy" He rebuilt his 280Z engine in his dads Barn in 10th grade to give you an idea, 45 years later as I walk up and he is finishing a old change and I watch him as he screws the new oil filter on and starts screwing it on with everything he has got! I'm like dude what the heck are you doing screwing a oil filter on so tight and ask you never read whats printed on the filter or box? 3/4 of a turn? He had NO idea what I was talking about!
A 60 year old man who has rebuilt engines but has no clue how to install a oil filter?

I only buy oil filters that have a rough coating like the Fram Ultra or the Motomaster OE plus which is a Champ XL with the coating. Then I give it the righty tighty with all the torque my calibrated left hand can produce. I ignore the amount of rotation. While lying on my left side I use my left hand to handle the filter. It works for me and a I still use a filter wrench get the filter moving at change time.

I always hand tighten the filter, but not being able to control the outside temperatures, I lube the gasket with 0w or 5w if below freezing and 10w oil if above freezing. In extremely hot weather 30w. Just joking, but if you hand tighten with the gasket well lubed and it comes of hard, so be it. It's better to come off hard than to leak and lose an engine because of not being tight enough.
Old oil on gasket, tighten as tight as I can by hand, ever so slight snug with a oil filter wrench.
No problems.
