replacing engine oil filter every change

[big bubba]

ok, have 3 vehicles all with different applications. they're high mileage (combined 700k miles on the 3)

5k change intervals w/full syn oil, oem filters. always change filter when i do changes. given that all the engines are in good shape, do i need to change the oem filter every time, or every other change given that they consume very little oil between changes?
i ask a lot of my vehicles, & maintain accordingly. your thoughts, thx in advance.

I always change filter and oil at same time. Usually every 5K like you. No sense leaving a dirty filter in place with clean oil. Just my opinion.

Filters are cheap relative to engines these days.

 

[big bubba]

well i agree with the above, maybe why the engines are doing well.
i just got to thinking though since some recomm 10k oil changes w/full syn (which i'll never do), that maybe it would apply to filters, esp if the change is 5k intervals.
just wanted to hear opinions, regards

Why would you dump a quart of dirty oil, into a reservoir of new, clean oil by not changing the filter? You would essentially contaminate the new oil instantly.

IMO, you should ALWAYS change the oil filter when doing the oil change.

I also think that waiting until 5k miles to do oil changes is far too long, unless the miles are all interstate miles. I do mine every 2500 miles. I've done that ever since I was 16 years old, and I've NEVER had an engine problem. (now in my 70's)

I would never risk it for the cost of a filter.

duffer: followed your change interval schedule with dyno oil for many years. when changing to full syn (castrol) i bumped it to 5k intervals w/oem filter.
just curious to see if i really need to change oil filter every time as well always using the same oil type, etc. regards

Anyone else here besides me not trust oem recommended oil change at 10k intervals?

Book says 10k on my Ford Escape, do 5k with Mobil 1

Hopefully you’re kidding, or at least hopefully nobody copies you.
That’s unnecessary, wasteful, and not even good for your engine
