Should I Change My Oil Filter With Every Oil Change

Not changing oil filter at every oil modify?

I noticed that some manufacturers specify to modify the oil filter simply at every other OCI.

Honda, for example, has a "A" service on the maintenance minder system which is replacing engine oil only. They also have a "B" service which is a oil + filter alter. That means that the oil filter usually volition not be changed for effectually 15,000-20,000 miles since the average OCI on maintenance-minder equipped cars is around 7.5 - 10k miles.

Does anyone on here actually follow this approach?

I change the oil filter with every oil modify. Still, I likewise recognize that I accept absolutely no empiric prove that such a practice is necessary, while a company similar Honda most likely does accept such information. Furthermore, I recognize that, as long equally the air filter and engine oil are doing their job, and then it is unlikely that the oil filter would get sufficiently clogged with debris that it requires replacement with every oil change rather than every other. Still, I exercise information technology because it is relatively cheap and it is a addiction. And I experience better nearly it, even though information technology is a placebo effect.

I'm sure Honda has some sort of reasoning, merely to me the extra $5-$x a yr on changing the filter every service seems similar pretty cheap insurance on a $30k investment.

• #4

I feel ameliorate about information technology, even though it is a placebo issue.

From what I've read, Honda'south rationale for recommending the oil filter be changed at every other oil modify was that the oil filter became more efficient at filtering as information technology was used. Of class, if you let it go for too long information technology would clog and become into bypass, but I'd assume Honda and other companies' research showed that filters could last 20k miles without going into featherbed.

I recall reading that in many owners manual and never agreed with it because:

1) A new oil filter, like a new air filter allows more flow with less brake. I don't want whatever restriction in my oil menstruation.
2) Leaving the erstwhile oil filter is also leaving a half quart of muddy oil in your engine.
3) How practice you lot know how dirty or clogged your onetime oil filter really is?
4) Spending $viii or $ten for a new oil filter is pretty cheap insurance.

But my 2 cents.

I e'er practice both for an oil change. At to the lowest degree I assume that'due south what's being done when I take it in since that'southward what is listed on my invoice.

I take read that before, and actually don't understand it. Even if the filter is fine, I yet want to remove it to go the old oil out (unless it is mounted what I would call upside down, as it is in my Cobalt). If I am going to go through removing it, why wouldn't I become ahead and supercede information technology?

I have never seen this listed ( I only drive Toyota vehicles ). I ever modify the filter every bit others have noted for 5 - 10 bucks every oil alter is information technology well worth the insurance.

For a newer automobile you tin can practice this if its a decent filter. You will not clog a oil filter up in 15k on newer cars with new oils.
The problem is how do you know if y'all filter is a good one, leaving former oil in when you alter it, and so on...

So yea you can become past but I rather use a $2-three filter and change every time and then use a $10 filter and change every other.

• #10

It's stupid. An OEM filter is $5 or less. Change it every time.

I don't know of whatsoever who don't alter their oil and oil filter at the same time. It is true that the oil filter is more than effective with smaller particles over time, but it is also true any filter only work if they are replaced/cleaned. I suppose the answer people want is when. Since most oil filters are cans, yous'd accept to cut it open. The ones that are open filter cartridges, since you have already taken it out, might as well put a new i in instead of spending time to clean the oil off information technology and inspect.

I wouldn't worry likewise much about the oil filter not filtering out the microscopic bits. Current oils is Crawly the past 5-7 years. They volition take care of it. If it continues to carp you lot, go a magnetic drain bolt. I tried a cheap ebay ane. Works well. It didn't better oil analysis much, but whenever I alter oil I do always stop up wiping off ferric dust off it.

while i agree its stupid not to alter out the filter. I just wanted to be an picky a-pigsty and say LOL @ 30k honda, yes i know loaded ones are that much or their trucks but i would feel silly paying 30k for one. And also the $5 filters are slowly going abroad, all these cartridges are costing $eight-15 now. Pretty annoying.

Either way. If OEM states it, they have their reasons behind information technology BUT i'm waste product my on a new filter for slice of mind.

I know that toyota specify a lower grade filter for the US market, considering customers wait 5k oil changes.

They specify a higher form filter with more than filter material for the EU market where the oil service interval is 10k miles.

Back in my younger days, we would use a roll of toilet newspaper to filter the muddied oil under depression pressure and reuse the oil but supersede the filter. That worked on a Hudson or flathead; While I have some empirical knowledge such equally after 100,000 miles when doing a cheap rebuild; rings, reseat the valves only only micing (Using a micrometer) to check the crankshaft journals; both chief and rod. Unless you constitute something wrong and had to turn the crank; you would use the aforementioned bearings if the owner changed his filter regularly. I rebuilt enough engines to empirically say I saw no difference between just cleaning the oil every other time and irresolute oil every time only those who drove an extra 2,000 miles between oil changes paid more money at rebuild time then they saved.

That was then, modern engines run hotter (more than efficient) and much longer between oil changes (oil cost 30 o xl cents a quart, 2 dollars to change oil was 2 hours work before taxes). I suspect the additives and other stuff, smog control that put crap dorsum into the engine (And allows use to breathe the air in our cities), higher RPMs and the relatively costs of totay'due south oil filters; you would be foolish not to change both; even if the manufacture says every other time is ok because some marketing guru tweaked the numbers to reduce the cost of maintenance judge.

Had an old Studebaker back in the 1990'due south that had no oil filter. Information technology was an option on the engine. Engine had a block-off plate over where the oil filter would reside. Required the use of not-detergent oils. Had an oil bath air filter, too.

Of course, this was on a machine that had cipher power accessories....no ability steering, drum brakes on all four corners of the automobile with no power assist. Those were the days....all-time forgotten.

I have Fumoto valves on my vehicles. One time when I was close to an oil change and didn't have time to modify information technology before a long trip, I just drained out 2 to iii quarts and then topped her off with fresh oil. I generally changed betwixt 3000 and 4000 at the fourth dimension which was pretty low anyway even for conventional oil... So pretty sure it didn't hurt anything... But probably did help versus just going on the trip and worrying about it all after.

while i agree its stupid non to change out the filter. I just wanted to be an picky a-hole and say LOL @ 30k honda, aye i know loaded ones are that much or their trucks only i would feel silly paying 30k for one. .

Have you checked new motorcar prices lately?

A Ford Focus tin can cost close to 30K these days if you tick all the options.

I know that toyota specify a lower grade filter for the US market, because customers expect 5k oil changes.

They specify a college grade filter with more filter material for the European union market where the oil service interval is 10k miles.

All engines with constructed oil with the exception two engines that Toyota uses call for 10K mile oil changes.

From the Toyota Spider web Site:

What are the oil change intervals using synthetic oil?

Merely Toyota vehicles in which 0w-20 constructed oil is required ( except for the 2TR-FE and 3UR-FBE Engines* ) accept been approved for extended oil change intervals of ten,000-miles/12-months. (Notwithstanding, you lot should continue to check the oil level regularly and top off if needed. That will help your engine become the total benefit of synthetic oil.)

And they utilize the same filters...

I did say fully loaded Honda...

The virtually I would pay for a focus st is 25k, dealers were giving away st2 models for $22k.

I know average call selling is like $28-32k but seriously in that location.. 40k on a loaded accord.... I think a coworker bought a $42k or 46k maxima and was bragging. I remember he should exist embarrassed.

Honda, for example, has a "A" service on the maintenance minder system which is replacing engine oil only. They as well accept a "B" service which is a oil + filter change. That means that the oil filter ordinarily will not exist changed for around fifteen,000-xx,000 miles since the average OCI on maintenance-minder equipped cars is effectually 7.5 - 10k miles.

its simulated economy to change the oil filter every 2d oil change. The filter cost is very low.

• #22

I modify it every oil change, but I practise 15,000 miles per modify on the Accord (Amsoil Signature).

• #23

While I don't think it's needed in newer cars with newer oils, I always practice it every time. As others have said, in the grand scheme of things, it's adjacent to cypher. I typically use mobile i filters and even at $10-12 (from amazon) the savings wouldn't justify not doing it when I already accept the automobile upward on stands just for the piece of mind.
