Jumping on filter every other oil change bandwagon

[BlueOvalFitter]

Let's say you were a Type I diabetic and you had to go to the hospital twice a week to have blood dialysis work done,due to renal failure of the kidneys.Would you want to keep the membrane filter intact from the first visit that week or would you change it? Just like they say,"Oil is the life blood of an engine." Same as blood,it's filtered through the kidneys,so with the dialysis machine the membrane is the filter,acting as the kidneys.

^OK, I do have to comment now. I actually used to manage dialysis clinics for the two largest companies in the stand alone clinic business. They DO reuse "dialyzers" (AKA membrane, or artificial kidney). They are flushed with solutions of bleach and water and then filled with either formaldehyde (YES, formaldehyde) or "Renalin," a solution of hydrogen peroxide and acetic acid. There is a claim that a reprocessed dialyzer is easier on the patient than a new one. Obviously, this practice saves money as the patients are dialyzed three times a week for about four hours each session.

The oil filter is a totally different animal and is not cleaned and flushed of old oil. Oil doesn't just become dirty. It shears and loses potency in the additives. I don't care what the manufacturer states. I am changing mine every time.

I agree. I was using this anolgy because my friend is Type I diabetic and has dialysis done weekly. After reading your reply I called her and she said the same; they change,flush,sterilize,etc.,the machine before each patient. I could have used another analogy but thought of her and the similarities of an engine oil and filter and dialysis.
I will change my oil filter EVERY oci, no matter what anyone says!

As part of my management training I actually worked in the "reuse room" and reprocessed a couple of shifts' worth of dialyzers. It is not work for those who are easily grossed out. Everything is flushed prior to hooking up the patient and there are test strips used to make sure that the preservative solutions are flushed out of the dialyzers.

I have commented about reverse osmosis water before. Dialysis clinics produce R/O water on a fairly large scale. Managing two clinics in Corpus Christi, where the tap water tastes lousy, is how I got turned on to drinking only R/O water. Any of you who are former Navy guys can attest to the benefits of R/O as well. It's still about the most efficient way to turn sea water into potable water.

DB,do you understand why I used this analogy? I just think they're very similar.I mean,who would want dirty blood entering and leaving their body through a dirty/used membrane? NOT ME! So,if you're going to pay "X" amount of dollars for a vehicle,wouldn't you want to take care of it and use a new filter to keep the new oil clean instead of having it filtered through a used/dirty filter?

I'd stop eating sugar and fat/cholesterol so the dialysis is not necessary in the first place. So how overweight are you? BMI?

I'm supposed to change the filter in my automatic transmission?
Manual trans too?
Ahhh crud.

 

[SteveSRT8]

^^^Very simplistic. Some diabetics cannot be controlled by diet. Might want to read up on that one!

Back on topic, I find it funny that there are some folks who see nothing wrong with using a turkey baster to "change" their PSF or brake fluid, or dropping the pan to do a partial change on their auto trans, yet it is a MUST that they change their oil filter every oil change.

 

[DBMaster]

BlueOval, I apologize if it seemed like I was critical of your analogy. I was actually getting too much into "narrative mode." I know exactly what you meant and agree with you.

As for the post above, transmission filters are a bit different. I don't know about manuals. I've personally never seen a filter on a manual, but that doesn't meant that someone out there hasn't made one. My last automatic was an 89 Honda Accord that only had an internal screen that could not be accessed. I drove for 300,000 miles doing only drain and fills every 30K with synthetic ATF. When the rebuilt unit was installed the rebuilder included a Magnefine in the cooler circuit and did not specify a change interval. I changed it after 60K on the rebuilt unit before wrecking the car. The Magnefine people claim that you can go 10K further on an ATF CI using one of their filters and that you can totally eliminate changing the in-pan filter.

Since I now understand what the in-pan filter really is I don't think I am going to change the one on the Mazda every time I do a drain and fill. There is no fluid maintenance specified for the Skyactiv transmission, but I figure somewhere in the 30K-50K range ought to work with a filter change the first time and then just every other time after that.

Go back and READ my post again! It is a friend of mine that was diagnosed at 6 years old,that she had Type I diabetes.She didn't ask for it,it was something she was born with but was not diagnosed until 6 years old.She is 46 now and is currently waiting on a kidney and pancreas transplant.She is in top physical shape except for this disease she DID NOT ask for! Do some research on Type I diabetes! BTW,I have Type II diabetes,which I got in 2000 when I was laid up in the hospital trying to fight Pneumonia. My body could not fight off the infection and this is how I got the disease! I'm not overweight,don't eat sweets,don't smoke,don't drink any type of alcohol,drink ONLY water,and very rarely eat meat.But I do consume great amounts of vegetables and fruit! And Crawfish!

 

[DBMaster]

Type II diabetes runs in my family. My brother and mother both have it. I have been lucky enough to inherit more genes from my father's side where they "only" have to worry about high blood pressure (which I think I am getting). I know a person who ended up requiring dialysis and a kidney transplant due to kidney scarring from a strep infection when she was in high school. SOME people can prevent or control diabetes with diet and exercise IF it is type II. Type I is just as BlueOval describes.

Both diabetes and high blood pressure can lead to kidney failure, especially if it is not kept under tight control.

I think we got really off-topic here, didn't we?

I'm the first and only one in my family,father or mothers side,to get this disease.

Anyway,an oil filter is cheap insurance for an engines life blood; oil.As I have stated before,I will ALWAYS use a new oil filter at EVERY oci!

 

[DBMaster]

I am one year older than you and have been changing oil since 1979. I have only done OC's with new filters every time. Before I had confidence in oil filters lasting for my 10K OCI's I used to change the filter at 5K and top off the oil. LOL.

 

[chad8]

i have done it in reverse. I left synthetic pp in about 12000 miles topped off and changed filters about half way on my Sienna.
i have also left filters in for 2 drain and fills.
Not very often....
I use the butt oil test. if the oil feels sticky or gritty , it goes. If i see sludge in the valve cap , I add mmo,short the oil change to 1000-2000 miles and change the filter. You can feel how heavy a sludged up filter is. Even after you let it drain a day or so.
Almost every car is a different situation.
Same with the human body. No hard / fast rules.

 

[Cristobal]

Anyone think that a Bosch Premium oil filter (it is a 3422 so a little oversize) can last for 15,000 miles? That would be for me two oil changes.

 

[DBMaster]

The 89 Accord never developed any sludge. After about 150K miles it had the usual brownish color on the underside of the valve cover. All I ever used in it was synthetic oil, 10K OCI, 355,000 miles before wrecking it.

But, as you very wisely state, engines differ much like bodies. What works for one may not work for another.

All toyota engines are easy on oil and filters , but 15000 miles on a 6 cylinder is pushing it a bit for a bosch especially if its an standard purolater. I'm not even sure . The distance plus would be a better choice. The idea would be more possible if you put 15000 on in less than a year with a lot of highway driving and the motor is in great shape..
Think about it . the 6 cylinder has 1/3 more potential crud than a 4 and the same amount of oil.

My cousin uses FRAM OCOD on his Toyota because John Force uses them. And,i'm serious about that; he told me!

 

[oldhp]

John Force uses Purolator filters painted to look like OCOD.

Honestly,I wouldn't know,because I don't care if he uses ST. If my cousin wants to believe that,who am I to burst his bubble.

 

[oldhp]

I can't go to bed without confessing....
I was just kidding.
I don't want to dream a giant Purolator filter chasing me!
