True. And there is no by-pass filter at a smaller micron size that can be used on our bikes.

And how about shearing? Is that all made up??
And do you understand the difference between our bikes and a 16gal capacity diesel motor with by pass filtration?
So why do they re-refine oil chemically instead of just "filtering" it?


Still waiting.

 

LOL...........

So Doug you have 300k on the same oil .... so to use your own quote from OZ

So Doug you plan on this nice little acidic and contaminated brew circulating around
that motor forever or what man ?????

Oh yeah ............. I'm gonna need that super duper ....no oil change filters for my
bike too........so I can keep the same oil forever ............ MAJIC filter name too please .....LOL

May I recommend a visit to BOB

 

I think what Doug is saying (I haven't read all of this) is that the oil ITSELF doesn't degrade, it's the additives like lubricity improvers etc which go off in time. The basic oil is OK IF it's correctly filtered.
I would agree that you can re-use oil IF it's had all the contaminants removed, and the additives replaced to return it to it's original specs.

The point about poor filters is well made, but most bike filters won't fix the particle problem. An oil change is all that will.
Diesel engines generally have two filters which allows them to run much longer between oil changes.

Are we comparing apples to oranges here.............?

 

I am not saying there is a Filter that will let you use your oil in your CBR forever. I am just saying that people are more worried about oil and not the filter.

Trout you know I changed my oil and the filter (k&n) leaked. I did and oil change again not even having 300 miles on the oil. Then I changed it again at 1800 miles just before I rode it to Tenn.

I get my oil analysis every 12,000 mile on my truck.


Sorry there isn't one yet


Yes

 

Exactly, because there isn't one.

As they should be. The level of filtration will only be so good for any bike with the filters we can use.


So what is the magical filter that we're all missing out on?
I use the extended size purolator pure one. I don't use fram becuase I hear they suck, and everyone seems to say the same thing.
But even with the Pure one, my oil will only last so long.
The OCI difference between a good synthetic and a crappy dino oil makes WAY more of a difference to me (and test results) than whether i'm using honda filters or purolators.

 

No, No, NO People should be more worried about there filter than there oil. The contaminants is what harms your engine. The oil would last a lot longer (forever) if there was no contaminants. That is why you should be more worried about your filter than your oil.

 

Doug, all due respect, but there's little logic to thinking that motor oil does not wear out. Yes it will remain slick between your fingers and even unloaded bearings, but the engine manufacturers and oil refiners have some well educated people. These folks tell us oil is only going to live so long. The engine guys don't want to buy new motors for everyone so they say change the oil. Of course the guys at Mobil want to sell more oil but the test labs that do SOAP checks don't belong to them, and they say change it. Turbine, reciprocating, diesel, gasoline, doesn't matter, chemical and molecular changes happen to oil that a filter is not going to reverse. A filter has a micron rating for particulate size that will pass. That is all. For BEST results change both.

OH, ...uh NE1000F, I don't use that oil but change my Mobil 1 every 3000 miles, and the filter. Hope that helps.

 

I'm skipping over all the other stuff you're wrong about, but you could at least answer the one big question that I'll ask again:

What is the magical filter we should all be using.... the one that none of us are worried about???

Is it wix? Purolator? Honda? Fram? Quaker state? (used to be purolator, now fram). Motorcraft? Mobil 1? (purolator)

Most filters are rebranded from one of the other manufacturers anyway, so that will be fun.

If I choose a purolator filter (which I do) and can get 8k out of Rotella T6...... how much longer would my oil last with say.... a wix filter? If wix is worse, how many less miles will I get?
Same with all the rest of them.
Let us all know!! You're holding out on us, Doug!

And if I change my filter 10 times over the course of the 8k miles, how is it gonna filter any better than if I just stuck the the original filter? Unless the media is blinded and going into bypass, isn't it gonna filter the same as the original?

 

Holy **** ....... this one still in play ............! LOL


Doug .......seriously Dude point well taken on using a quality filters

Fram I personally stay away from, prefer wix/napa, Hi Flo, Purolator & derivatives
K&N , Bosch & STP .......that's it !

But .......when the manufacturer of the motor specifies
oil be changed at prescribed intervals .........that is good
enough for me man I'm not going to let the additive
package deteriorate to the point where seals harden and
premature wear occurs ! Why would you want that ?

Trout if you did for some bizarre reason (which I know you
wouldn't) change the filter ONLY ....10 times in 8k miles
then you'd have to add back in 10 filters worth of oil
so .....ya are still adding new oil when a filters worth
comes out ......... SO Doug ........even just changing
filters ....Guess what .....you still to put in new oil for
what you just lost with the filter change ... this is nuts

A crazy kind of keyboarding exercise I guess

 

Is it me or did this thread get way off topic?
