I am changing oil on two cars, a 2008 civic and a 2009 mazda 3. On the civic I have been doing 5 month or 5,000 miles with dino but I have been only changing the filter every other oil change. Is this ok and does anyone think it might void the warranty or cause me to run into problems if there is an issue with the engine.
Oil filter interval

Why not just change the filter when you do the oil? It's worth the $3-$5. It's kinda like taking a shower and putting your old undies back on.
I remember the owners manual on my 99 Accord said you could change the filter every other oil change. As long as your om says you can do this it shouldn't void the warranty. I thought someone on here did some uoa's and after the interval without changing the filter there was a noticeable increase in particulate.
If I had a Civic with the maintenance minder I'd put synthetic in it and follow the minder down to 15%. Even a good quality dino like Havoline, Penzoil, MC syn-blend, or Mobil 5000 you would be in good shape. Just not sure I'd trust the MM with dealer bulk oil. However uoa's support the mm very well.

Wrong forum section but I would stick with factory recommended.
Civics are likely a very clean running engine and I thought OCI was 10K with filter every other time. But I have never owned one.
The only way to know on a filter is cut it open but you then need to know what criteria you use to judge it.

This is untrue. On a new and clean engine, the filter does not at all reach full filtering capacity at 5k miles. In fact, Honda recommends a filter change, every other oil change.

I don't think anyone's suggesting that the filter's life is over at one OCI. While it hasn't reached its filtering capacity, it is full of old dirty oil. Why mix that with the new, clean oil?

That has always been my opinion, and there are mixed feelings about removing draining and re-using an old filter, leaks. Me I pitch them at each OCI.

On the other hand, the oil is 90% cleaner than it was, and oil filters, like air filters, are doing a better job of filtering as they begin to fill up. Change the filter too soon, and you are missing the best filtering that the filter is capable of.

100% of old oil isn't drained out. There is always some left over and it will mix with the new oil as a result either way.
Filters are also known to filter better once they clog some, so you are actually doing more good for the engine by filtering smaller particles through; something a new filter may not have done.
You can always take the old filter off and drain out the remaining old oil out to have a minimum amount of old oil mixing with the new.

In my car, the oil change is 4.2 qts. Filter is an additional 0.2 qts. While the whole engine capacity is 5.6 qts.
So if I chnage oil only I change 75% of the oil, and if I change the oil and filter I replace 79% of the oil.
So Im always mixing in new oil with the old.
Nevertheless, I am in the change filter/each oil change category. Mostly because its easier for me to remember.

But what if you want the better filtering offered by the slightly used oil filter? You know, at many times in the past and present, manufacturers have recommended using the same oil filter through two oil changes. Some Hondas that did not have the OLM recommended this a year or two ago. I was just perusing the owner's manual of the 1980 Pontiac Bonneville that I owned from 1980 through 1986. It recommended an oil change every 7500 miles or once a year, and a filter change every other oil change. In my cars, I have never cut open an oil filter that looked like it was anywhere near clogged. I never really see anything but oil soaked pleats.

The residual oil is negligible ..the filter is still vital
That's if you qualify for the mileage interval. If you're into the time interval ..then it's every time.
There's nothing "unclean" or "unwise" about it. It's just personal preference.

+1 ...it only takes 5 min .to change the filter,and it won't break the bank ..

Hey Rocket Science...Now that is an idea....Maybe they used some of that rocket science to engineer the new cars coming out for sale to the public....Opinion only....

It's not a time factor ..it's a waste factor. If you're changing out oil and filters like their yesterday's underwear ..then you can go cheap (in most cases). If you're using upper level fluids and filters ..it's sensible from a cost:benefit basis to get the maximum (or as near as possible) utility out of them.
Going long ..you can use a better filter without waste.
Filter life and oil life don't HAVE to have any relation to each other. This is especially true if you're going long and do not buy oil that can go the distance (or aren't going to take it the distance).
It's just a matter of perception at that point.

What is the logic in having an expensive vehicle, and then trying to cheap out on filters that protect the engine? And NO, dirty filters do not filter better. Wheather it's oil or air, oil or air molecules will not pass through dirt molecules, so when they can no longer go around the dirt, they push it through.
Honda says specifically in the service manual to change the the oil filter...EVERY OTHER oil change.

I guess Honda must be wrong then huh? Do you have anything to backup your theories about...what did you call them "dirt molecules"
