Waste of money.

Filters even become better when used for extended OCI if it is rated for it.


Balogna. Prove it.

I am all for 2x filter runs, but even I have a hard time believing the "efficiency increases enough to be beneficial" is a good enough reason to do so.

If the filter is rated for 15k, run it to that assuming you know your engine is clean.

I can do a 2x filter run in my Jeep and not tell I kept the old filter on with the the color of the oil.. and that is with the rather large xx16 filter size. If I had a Honda that took the little xx6607 size, it would be a no brainer IMO. A cleaner and quicker oil change is a huge benefit IMO.

Also, I have observed with my Jeep that it doesnt like filter changes. The engine will remain vocal with various degrees of lifter noises until 1.5-2k. I did a 2x filter run last summer and didnt experience as much lifter noise as I would if I changed the filter. The TG looked decent with a little over 8k. This is a good enough reason to me to do it.
 
The only way I'd run a filter twice is in an engine equipped with a cartridge filter that I could unscrew the cap pull and inspect the filter and let the oil drain from the housing. Any screw on filter gets changed every time I change the oil. Like I've said before I don't want to risk leaks draining and reusing the filter, and I don't want a filter that holds close to a qt. of dirty oil circulating the contents into a fresh clean fill of oil.
 
You can find some very good deals on filters if you use coupon codes, ebay, etc., so no I don't think it's worth the chance of going every other oil change. I can see why someone would want to do this for environmental reasons, though.
 
LOL. This is one of the topics that keeps on giving, and giving and so on, etc....

When I first joined this site one the first topics I commented on was running an oil filter twice. At the time I thought the idea to be heresy and foolish. But, came here to learn too.

I do now believe a filter becomes more efficient with use up to it's rated holding capacity. Some of the extended oci oil filters have a capacity up to the ~30+ grams of contaminates, that's a lot of junk. In a well maintained engine, that's way more than ample leeway. Now whether the efficiency increase is significant, not really important to me. More/most about getting ROI. Since joining I've run a BD+ twice to 13.5k miles in a Honda, and currently running an Ultra to 15k miles on a Tacoma. Believe those engines will out last the rest of the vehicle. And with the Tacoma filter location it was nice to leave the OF on for once. And based on my reading here and my experience, getting up to a pint used oil after filter removal would be a lot.

But with say Wix/Napa Gold being obtained
So unlike some, I have no hard and fast rule for using an oil filter for two ocis. I'm just now not afraid to do it in the vehicles I maintain. In fact if I choose to do it as explained above, I'm confident. My .02.
 
FordCapriDriver - Since you bring the oil to operating temperature on all your drives and your weather is very moderate, I think a filter along the lines of the Wix / NAPA Gold suggested by sayjac would be great option. A full synthetic filter would give you extra margin over the 6000 mile 2 yr oil change. A metal center tube would also be a must. I am assuming that your engine is in good tune and not producing huge amounts of soot.

I am also from the demarpaint camp and prefer to change the oil and filter together.

Hopefully you have enough info to make a good choice.
 
Last time I changed the oil on my sons Toyota it had 5,000 miles on a Fram Ultra Guard .I thought about leaving it on for another interval . I changed it out and found the element was loose in the can. It was a good thing I changed the filter.

We know filters can be defective in one way or another. I agree it was a good thing you change the filter.

10-4. We tend to scrupulously review competing VOA's to get an "edge" or whatever we think. And along with those VOA's we like to see certs like MB 229.5/229.3, or Porsche A40, or BMW LL-01. My oil filters hold a min of 16-20 oz of fluid. And there's another 3-6 oz sitting in the galleys directly above the filter. How would those VOA's look with 15% dilution from 4K-8K mile used oil (ie TBN)? Would Mercedes Benz, Volvo, BMW, Porsche and others still certify those same oils with up to 15% dilution? Maybe factory fills should now include 1 dirty quart of oil for conservation?

Ever since I pulled a Fram Ultra XG2 off my last 4K mile oil change, I'm not so sure about a 2X interval on the same filter. That filter weighed at least 2X as much as a new one. That's basically 3/4-1 lb of "something" extra in that filter. It drained for weeks too. It weighs about the same as a full quart of motor oil. And when I pre-filled one of these the last time, it took around 16-20 oz of fresh oil. So for a filter that can handle 32 grams of material - there's 10X-15X that in my XG2. And my car is no sludge monster.

The interesting part is that the Puro Pure 1 that preceded this XG2 didn't load up with much of anything. It was basically the same weight as a new one. Another XG2 is on the car so I get to check this again in May/June. It's possible the old filter has to sit out in the hot summer sun for days to remove every last ounce of dirty oil.


I ran an XG2 for almost 20k miles. Cutting it open revealed nothing resembling 3/4 lb. of solids.
 
The media was probably still soaked with oil too. Lets not forget small amounts of oil still tucked away in the filter.

Let it drain until the cows come home and it'll still have oil in it.

3/4 of a lb is 9 ounces.. just over a cup.
 
Hello everyone,

I was wondering if I can get some advice on a similar subject. I own a motorcycle (Honda CBR 600 F4i 2001) and last year I did only ~ 200 km of driving. Now I am asking myself if I should change oil filter considering that it only did 200 km

The oil filter I am using is Champion COF104 (http://ecat.championpowersports.eu/motorcycle/oil-filters/COF104). The oil used is Castrol Power 1 Racing 10W-40 (fully syntetic).

I am going to change the oil, however I am not sure about filter. Any suggestions?

If only 200 km on the filter, I would say run it another season. Oil filters will last 2+ years in use.

Thanks. It will make my oil change process less messy this time

Let's see, will the amount of oil left in the filter when the oil is changed, cause any difference? No, it's not the oil that breaks down, it's the adds, and the new oil willl replenish them thoroughly.

Will the contaminants in the filter somehow get into the new oil, doubtful that would ever happen. At least only slightly more likely than on the original run.

Now for the logic of it. A decent oil filter will cost something like $3.50-6.00, so is it really worth it to not put a new one on? That's for each to decide. To me, it's just not worth it. I like knowing if I'm a little long on an oil change I'm covered, so I use a new one each time. If you buy expensive filters, say an Ultra Guard, then you've just bought two decent filters, so maybe it makes sense to go two oil changes with it, I still don't.

Where is the "demarpaint camp" ?

Google maps could NOT find it.

Its been mentioned in a few posts just can't find it.

The 'demarpaint camp' location is highly classified for bitog security reasons. So it can't be found on any map including Google.

Very little is known beyond that, except that those in 'dermarpaint camp,' prefer to change their oil filter with each oil change. HTH
