Welcome Purple Pride, and don't be put of by this guy AJ. He's just a know it all and can't help himself. Purple Pride glad to have you participate.


Wow - thanks so much! I appreciate that.
Was thinking whether this was a mistake. Like everything, there's always good and bad folks. Nice to meet one of the good ones :)

Progress :)


I agree.. and my oci is right about the same as yours (give or take 500mi)

Welcome to the forum


Thank you too sir! I was going 5k due to the warranty, but now I stretched it to 7k, and that's good enough for me.
I've doubled my OCI since ~2006, so that's someone I think that is willing to learn and change, in spite of what some might think.
 
I too have worried about the waste generated by filters. The local quick-lube oil change places have a separate bin for oil filters, as does the local Wal-Mart lube shop. Evidently they cut the filters apart, separate metal from paper, and recycle them. Sure beats tossing them.

Even if not recycled, the waste generated by a car being trashed due to poor filtration is far greater than the waste of a filter being discarded. Filters are cheap, why not change them every time, particularly if they're recycled?

Let me ask you this:
Would you buy and use oil and filters that by your standards have been under-utilized?
That is - simply - used?
I mean, if you really believe what you say, you'd be willing to run under-used oil & filters in your car - correct?
 
Where's the guy who changed his Nissan Sentra filters every 3k but ran Mobil 1 out to 25k, adding a total of 10 replacement quarts in the process?

We need more guys like that here, more money than brains.

Sounds like a good way to wear it out faster and make you buy a new one. God knows they need the sales.

The filter lifespan is not in question.


What????

Okay ..two daily drivers. One has a 6 mile commute 2X daily, the other 35 2x daily.

How many miles does either car have in fuel enrichment ..the time that you produce most of your filter loading insolubles?


Let's for the moment, and just for demonstration purposes, say that 6 miles just happens to be the point where both engines can go into closed loop and out of cold start fuel enrichment.

Keep in mind that we're looking at it from the filter's perspective. Which one sees more material than the other??



errr....my head hurts. Never mind, I already put the 5k used filter back on w/fresh M1 10w/30. Hopefully my nxt oc will be before 2013. Thanks for contributing.

Ps - some of you nd to learn how to play nice

Essentially, both filters saw the same warm up mileage. What one didn't see was 100% of the fuel dilution and (probably) 100$ of the moisture retention that would have justified changing both the filter and the oil @ 3k/3m for the filter that ONLY saw the fuel enrichment miles.

Every car has to transition through some length of fuel enrichment.

The engine/filter that does 12k-15k a year sees many miles that have no impact on filter life.

I really don't understand going to the trouble of re-using a 3-year old filter, when you HAVe other filters on hand! You don't even have to BUY one!

Also, if you are already changing the oil, why not take the extra couple of minutes and put a fresh one on?

I've REALLY got to stop being suprised by the idiotic things people do on this site, but sometimes it defies even idiot's logic.....
 
Everyone needs to stop eating rocks & nails for breakfast...it's making you cranky.

The reasoning behind reusing oil filters is that after a "normal" usage of +-5k, the filtering medium hasn't come anywhere near reaching it's capacity for capturing insolubles. Again, I stress "normal" conditions & with deference to Gary Allan, this means a filter hasn't significant fuel enrichment duty. [yes Gary, I get it now]

Anyone who continues to shake a finger

at me or the many other like minded people here who've made an EDUCATED decision to reuse oil filters x2 or 3 times simply doesn't have all the facts. Even if filtering efficiency doesn't improve as more particulate becomes trapped, just think about how many MILLIONS of pounds (tons???) of hazardous waste we won't be generating!

All you have to do is read the complete thread that precedes this post...it's VERY educational. There's a lot of very enlightening input from intelligent open minded people. Especially Sidney004's post & the last one by Gary Allan...his earlier ones too if you speak Martian

if this were a 6 month oci I would run it again, but after having been on there 3 years, I personally would change it out.I have re-run filters on my car and bike with no issues.

Who really knows what would happen if you ran it again? Maybe nothing...maybe...

At some point, you have to put faith in oem's test data, yes?


Ohhhh. YOU don't have data - like you required from me, just your manual and the filter box?


That is data, the information the oem analyzed and prepared for the end user. Better than relying on complete ignorance.
 
I'll post again since you don't want to answer:

Must be a Dodge thing...my old Dakota's manual says this also. Always change the filter anyway, I can get Purolators for a buck on sale, not worth it.

saaboc -- you state on 1-16 "i'll prob err on the side of caution due to the 3 yr time span & break out a new filter.someone talk me out of it !" and on 1-17 " ... put used filter back on".
this thread reminds me of how MANY women shop. one wants a top. she gets 1 or 2 friends, and hits a mall. they go to about 9 different stores, and they don't like any of the 80 or so tops that they all looked at. go to mall #2, and repeat.go to mall #3 and repeat. ends up that said woman buys the tenth top that she looked at. said woman is indecisive, and needs validation to make a very simple decision. thus the reason for getting friends involved.
saaboc -- i'm not getting on you, man. i just want to thank you for starting this thread. it has given me a lot of laughs. have a good day.
 
Good grief. Am I the only one who's been reading the preceding posts? The dirty shirt/under ware analogy, while humorous, is hardly applicable here.

A "dirty" oil filter isn't going to give an engine a rash! On the contrary, what it will do is filter more efficiently due to the media being "enhanced" by already trapped particulate, which in turn permits the capture of even smaller insoluble matter.

It's easy to make a blanket statement to the effect of "why bother when a new filter is only a few bucks", but why perform unnecessary "preventative" maintenance? Especially when (in most cases) it's actually counter productive!

As previously stated by people smarter than I (several of whom who have actually cut open & dissected a few used oil filters)...to para phrase; Under normal duty (ie. a greater ratio of use w/a fully warmed up engine vs cold starts &/or short trips), a used filter is well short of reaching maximum capacity after 5k (or more). Additionally, it's also trapping more & more insolubles as the molecular network of fibers becomes increasingly layered with microscopic particles...THAT AREN'T BEING RECIRCULATED as they would be with your precious new "non dirty" filter!

Pack that in your pipe & smoke it.

PS - Re. "saving the planet"; I'd rather be part of the solution than a contributor to the problem. If every person held the mindset of "It's not my problem" or "It's not going to affect me", eventually all the misdeeds will trickle down through the generations...& our children or their children....ect, will suffer the consequences. It's very selfish not to consider that. Btw, I'm not some psyco liberal - I'm VERY conservative & I think global warming is a made up farce that's making the likes of Al Gore (the slimy sob) very rich. I'll never drink any 'cool aid' & to quote Michael Savage; "Liberalism is a mental disorder". I love that guy...& the planet too.

Go smoke that too. God bless the USA!

Oh, enhanced! I get it now.
I'm going to start selling "enhanced" oil and filters and spark plugs and coolant soon.
I think you are helping me to make my 2nd fortune!
Thanks dude - can't wait to start smoking all that money...

This is the point where someone, like myself, says, "Move on pilgrim. There's nothing for you here."

Now you're just being played for how much you'll continue to twitch. The people who gleaned value from the content aren't even posting. The rest is the equivalent of walking into a bar and spilling someone's beer and pretending it's an accident

Martian? I don't hang with that intrasystem trash. You need to go further out (or over/up/down-depending) to get good holmy's to hang with.
