more micron or less?

[digitaldrifter91]

i been using alot of money to run my bosch oil fiters for my 3500 mile oil changes in my 91 honda accord. i was looking at the supertech filters that filter 98% multipass @20 micron while bosch is @15 micron...is it wise for a 20 micron filter to be run on my accord than just running a 15 micron filter?

2 bucks compared to 7 bbucks is what i like =). im going to run auto rx soon with the supertech filter cause its cheaper...but may just switch forever...gimme ur opinions...obtw im running regular oil 10w-30

Well since you are dealing with a '91 model: Its life is limited. I personally would have no problem with the Supertech. I use it on 2 of the 6 vehicles I maintain.

i would stick with super tech... i mean, most hondas go a long time with plain oil and fram or OEM filters...

my friends 92 accord has something like 217k and he never maintains it, and it runs strong.... maybe oil change every 4k on dino oil, never trans change (all 91's start to shift hard at some point) and never a coolant change.

 

[digitaldrifter91]

these accords run really great, my uncle has 356k on his 91 and has no problems. i guess ill downgrade to supertech from bosch...save me a little cash. ill use the remianing cash for a fuel treatment...hehe sounds good

It matters when the smaller micron particles get covered in carbon and turn into carborundum particles.This is an industrial abrasive and they usually get bigger the longer you run the oil.Sure by this time the filter is trapping the 30 micron sized particles..but there was a study by Detroit Diesel that was a little eye-opener when it comes down to smaller particle removal and engine wear.Why have by-pass filters on big rigs if smaller micron filtration is non-sense?If you can't afford a better filter then thats a no brainer,but why take a chance on engine damage if all it takes is the price of a couple of cups a coffee a month?

Carborundum is a trade name for silicon carbide (SiC). Silicon carbide is prepared commercially by fusing sand and coke in an electric furnace at temperatures above 2,200°C. Yes, some of engine particles are abrasive, but is SiC really produced in an engine?

According to Bob's homepage it is,and I have read this in other journals as well.It is not industrial grade,but is getting close to diamond hardness in some engines.

True but you forgot to add that the by-pass filter also gets the small stuff out too,so the oil can run longer and cleaner...why didn't I get a welcome on this board..

 

[RalphPWood]

No one has ever made a small filter that can both clean oil and filter fast. It is all a trade off. I gave up the system of using filters that don't work then draining the dirty oil 40 years ago.
I just installed an adpater on my Camry today that eliminates the full flow filter. The full flow filter is pretty much useless in a good engine after it is broken in. If an oil filter is not submicronic I don't need it.

Somethings wacko with the board...tried twice to reply and nothing happened.I'll try again.So you are saying we don't need oil filters on our engines?Who's up to this test on their engine?

Greaser,
As you know a modern engine using modern motor oil has almost nothing in the oil large enough to be filtered out by a full flow filter. I feel comfortable using only a submicronic bypass filter on my Camry to eliminate the wear caused by the small engine wearing abrasives and tossing the almost useless full flow filter. I've never seen any logic in draining dirty oil and replacing a full flow filter that is still clean
When I was younger I worked in a full service gas station. I checked the oil on a car with a Frantz oil cleaner and got a lecture on how to keep an engine from wearing out and eliminating routine oil changes. I learned very well.
I brought back the Motor Guard bypass filter because I like it better than any of the others.

Hmmm...very interesting..there are no particles 30-40 microns in a running motor?If you are using a by-pass filter the regular oil filter IS just going along for the ride.In most cases we are not running a by-pass and the regular filter is all we have...and I'm sorry...they DO their job.Try and tell the dealership that using a oil filter is nonsense when you go in for a warranty claim

Like I said, where does all the particles in the oil come from by %?

Silica(quartz) is the biggy...mostly from induction ie. filter is not doing it's job or a leak somewhere in the induction system.Then there's the crankcase vents...another concern.Wear metals coming from normal running engine,chemicals from reactions in combustion...it's an assalt on your engine from everywhere...I have to lay down now
