replacing engine oil filter every change

[Too many Kubotas]

Additives can fall out of suspension, and the oil itself can get condensation in it.

That's about all that can happen to stored oil as far as I know. Then again, I do remember seeing The Motor Oil Geek showing old oil that wasn't exactly good after a while.

i do agree, storage is important

Usually oil is stored in a sealed container? When I have a
2.5 and only use half I squeeze the container to get the air
out and screw the cap on tight. I have never had any problem
with water in oil. City folks IMHO are more prone to have water
in their oil because of all the short trips being in town. I live 3
miles from the hwy way and the engine is at normal temp when
I enter the hwy way then 10 miles to the edge of town
For my truck only oil filters from Dodge/Orielly's has them

good way of looking at that. short runs, in vehicles or tractor w/o letting engine temp help burn off condensation is a reason for more frequent oil/filter changes.

going back to my original question, basically, what's the life of an OEM oil filter in comparison to the life of syn oil recommended interval changes for your vehicle?
(given the engine's in good shape w/little oil consumption)

again, apologize for rhetorical thread, wanted to see your responses

Condensation can only happen when the oil is in a completely open system where air can go in and out freely, which in a standing engine not is the case. And once more: those that tell you to change "old" oil, do not throw away their stock, even if it stands for years. When people buy oil, they don't have any idea whether that batch was made the day before or five years ago; however, from that moment on they start counting the recommended period. Only makes sense for driving up sales to the uncritical crowd.

In this strategic turn-over pushing context: in the 50s, 60s and even the 70s the owners of cars were told by the dealers that in a few weeks the one-year guarantee on their car was going to end, so they better should buy a new one right away, and a big majority took again a full bank credit to buy the latest model; that is the tactics where the US car industry got big with. I never heard of anyone ever coming with the only right response: "Are your cars that bad that after just one year they start falling apart?"

Filters are more important than the oil. I once had a small Honda car, that a mechanic dared me to just change the filter and never the synthetic oil. I drove that car over 100,000 miles and only changed the filter, adding just enough oil to compensate for the changed filter. Never had a moments problem.

Even condensation or water in the oil is not a problem in itself. Once had a Ford tractor with gasket leak where the water would leak into the oil every night. I refilled the radiator and used the tractor every day. Milky oil in the morning and clean-looking oil at a normal level every evening as the water boiled off with a little use. I used it hard every day. It probably would not have been good to let it set for a long time.

Years ago with one of my first cars, I was told to change every 2500 miles which I did for years. (Conventional oil with filter). When synthetic became more popular I was told it would go 10,000 miles so that is what I have been doing for 20+ years now. In that time I have had 4 different trucks that have gone 198k, 195k, 175k, and my last one was at 265k when I sold it. My new to me truck currently has 67k on it and (you guessed it) it gets its oil changed every 10,000 miles. And to answer the OP, yes I change the filter each time too..
Good luck.

so i'm hearing filter changes are more important than engine oil changes with an engine in reasonably good condition? my vehicles are all pre engine oil analysis sensors, so i go on my own empirical experience.
all i'm trying to figure out is do i need to change the oil filter every time w/syn @ 5k interval change, then both @ 10k

My car has well over 700,000 miles on it. Oil and filter change every 10,000 miles. Head and oil pan never removed. I might use a quart of oil between changes. Generally an hour or more of driving between shut offs.
