Oil Filter Change vs Engine Wear

Over 70% of all machine wear is realted to contamination, and dirt is the number 1 source of contamination. Reducing the dirt level in your engine reduces the wear in your engine, so what is the best way to keep the dirt level low? Frequent oil filter changes and high quality air filters (not high flow air filters) can remove dirt and prevent dirt from entering the oil system.

These used oil drain analysis results highlight the difference in engine wear attributable to dirt contamination.


Apparently Honda doesn't think so with their 10k-20k mile filter change intervals.

It clearly shows that changing the oil filter regularly removes more dirt (silicon on the oil analysis) from the engine. When you remove the dirt, you remove the particles that cause abrasive wear in the engine. Chart B shows the results of the wear metal analyis from these used oil drain samples. The oil analysis shows that less dirt (abrasive particles) equals less wear metals (less engine wear).

Well lets think about this
1)No doubt that dirt is the enemy
2)Apparently Honda doesn't think so with their 10k-20k mile filter change intervals.
3) I give up!!!

LOL I think it's probably important to consider racing conditions.

I agree with "high quality air filters (not high flow air filters)", but I do not agree with "Frequent oil filter changes" for daily driven cars/trucks. Do they change oil filter at every pit stop at Indy500 ?

They use M1

New filters don't filter as well as used filters. This is very odd and those charts aren't very helpful.

Dropping the filter also does remove some oil.

 

[Gary Allan]

Buy a filter based on how much you'll get out of it.

Insolubles. It's all about insolubles. Small ones you don't have to worry about unless you're going long on the oil. The big ones get caught easy enough so those that get through aren't in any appreciable number ..especially if you're dumping the sump and resetting the particle count to zero.

If you're going long, you need to trap more of those that got away. You also need holding capacity.

sorry dude, i change every OCI which is usually 6-7k although one time i went 12k on a M1 filter using supertech then PP...i think a oil filter is pretty well used up after 10k with reg oil but of course i have known more than a few people who dont change oil or filter very often and motors run

OFF THE SHELF!

What a convenient report and it comes from a site that sell oil and filters, I guess sales are hurting. The same thing happened when auto sales dropped like a rock, we had some "studies" that suggested it is more environmentally friendly to buy a new car every 4-5 years than keeping one for 15.

I keep hearing this statement. How do you know this? Or just theory?

Ive seen a fair number of studies through the years of filter media (not always specific to oil). Essentially the filter will filter better and better up to the point it causes the bypass to open. Thats because a layer of dirt helps close off a direct route through the pores becoming in essence a prefilter.

 

[Captain_Klink]

?do you think that as the filter gets older, it starts letting particles through - is don't understand how that could be, unless the filter medium is completely clogged, and the oil now goes through the bypass. usually, as a filter gets older, it becomes more and more efficient at filtration, so it is just the opposite to what you are worrying about. same is true for air filter, - if there is some dirt in the filter, it stays on the OUT side, and there is NO way for the dirt to work its way to the inside. so all in all, there is a failure to understand how a filter actually works. changing the air filter regularly, allows for the engine to gulp large amounts of air, at high rpm. otherwise, for normal running, the air filter has a very long life. I normally change my oil filter every second or third time, depending on my OCI.

 

[MegaCorp]

Very little dirt in an engine anyway unless you do gravel roads, or are running in a construction area. I always change the oil filter every other oil change just to be safe. Never seen one go into by-pass (always hot to touch) or never seen anything in them when cut open.

 

[mechtech2]

If a filter is perfectly OK for 6-8k [or more] with a full synth, why is it not OK for 3-4k dino changes?
A filter change was recommended every other oil change years ago - this was standard, and some mfrs. say this now.
I started to use this technique recently - a new filter every other change with dino oil.

I foresee zero problems.

 

[Gary Allan]

Short OCI's, you're wasting your money using a top tier filter. You're not going to leave the sump in long enough to reach any appreciable level of unfilterable insolubles. If you're going long, then a better filter might pay.

That is, for someone doing 12k+/- a year, while doing 4-5k OCI's there's no point in buying a finer filter if you're going to change it out every time. You may feel better, but there is no benefit of merit. You're dumping the sump in a timely enough manner to limit any of the particles that aren't trapped by the $3 filter. A filter gets its rating at the end of life. The nominal rating is much more indicative of its out of the box performance.

You can rationalize the added expense if you feel the need for a silicon ADBV. They tend to only be offered in the upper tier filters at added expense.

That's just too funny...

Quote from the article:

Quote:
For efficient pollution control it is necessary to have up-to-date emission control devices and to keep them in working order. In practical terms that means driving a newer car and adhering to its maintenance schedule. Here we must find a balance between replacing a vehicle that we've already paid a high ecological price to build and one that works better from an emissions standpoint. Currently emission controls are mandated to work for 150,000 miles, which gives a reasonable guide to replacing a car.

Then there is the argument about driving an older vehicle, but fewer miles. To a point this is sound, but the decrease in pollutants from newer cars is so great that once a car is much older than five years it doesn't take much driving for it to equal or notably exceed the emissions of a new daily driver. Still, for truly occasional-use vehicles it probably makes sense to keep an older one handy.
