You don't have to change Oil filter during Oil Change? True?
Discussion
Every time I've had an oil change, I've always had the oil filter replaced, too.
If you're putting in fresh clean oil, why would you not change out oil filter too?
Wouldn't the old oil filter (which is probably dirty) pollute the new oil that just got put in?
Today, I saw the mechanic change out the oil and the air filter but he didn't change the oil filter.
I asked him why? I wanted all of it changed. He said, you don't have to change it every time.
You only need to change the oil filter once every 2 times.
Damn...is that true? I've never heard of that before.

I take its a 12 month servicing? If so then no not heard of that one before. What car is it?
Yes, every 15,000 km or every 12 months servicingCar: Daewoo Matiz (2001)
I only logged about 6,000 km since my last oil change BUT that was about 18 months ago since I last did oil change.
This was only information I had. There wasn't a sticker on my windshield or anywhere that shows it. I never came to this
garage before (first time) and he never checked anything with the computer to find out when my last service was performed.
I just told him I wanted an oil change, and he only changed the oil and air filter but not the oil filter until I told him to change it
and then he told me you only need to do it once every 2 service times. Huh???? I don't believe him.

I have had some cars where the manufacturers schedule advice was to change filter only every other oil change so yes heard it before nothing to worry about. Being such an inexpensive item makes sense to change it all the time but I don’t think it will be any problems changing it every other oil change.
What does the owner’s manual say?

A new clean filter will flow better than one holding a few particles, so I would always change it with the oil. But that is partially because Id always do this job myself.
Does it really matter if you dont change it with every oil change, doubtful. On a brand new engine, yes, vital. On a Porsche or a Ferrari, for example, irrespective of mileage, fundamental (only because prospective owners would be "anal" about such things, not because its necessary). I see no reason to change it every time in this instance.
Nice to hear that the mechanic is probably saving you half an hour of labour and the price of a filter and putting this before the profitability of the workshop. I'd keep hold of this guy

Thanks for the replies and clarification. It's good to know that he wasn't being dishonest or shady.
Actually, the job looked really simple. He literally did it in just a few minutes. I have done my own oil changes before but when I calculated the total cost of the new oil, air filter and oil filter, it comes out to about 16 pounds (currency converted) (if I ordered them online and had it shipped to me). Then I'd have to do the manual labor myself and spend the time, to save 16 pounds. Or just pay him 33 pounds to do it for me like I did.

Changing filter every other change died out with 3000 mile oil changes about forty years ago.
^^^ Wot 'e said.Too cheap/quick a job to not do, I would always do both together then you:
a. Get more of the old oil out.
b. Have a new clean full-flow oil filter from the off.
c. KNOW when it was last done.
Let's face it...you don't have to change the oil either.
Do what a lot of main dealers do...and do nothing for 3 years until it's out of warranty and then servicing falls to outside garages who spot what the dealers havent done for the warranty period.
But really....you should have got the old oil, and poured it over the t

I was told years ago (and don't know if it's true) that the new oil contains fresh detergents which wash crud out of the filter and back in to the sump/pool.
I've always changed the filter when changing the oil but most of my work is on agri vehicles where the filters hold over a litre of oil.
On my little Clio my tea mug holds more liquid than the oil filter, it's tiny, no way would I not change it.
Do you people cut your removed filters apart to have a look at what debris is in there?

The new focus is only change oil filter every second service................ might have something to do with the 28 screws you have to undo to remove the lower cover!!
It's quite a faff on the latest VW engines and it wouldn't surprise me if they don't get changed. Ours should have had the diesel fuel filter changed at its last service - I can't say 100% it wasn't done, but it looks remarkably undisturbed.I have seen comments on US forums that Honda's there only have the oil filter changed every second service but I think they're on variable servicing there and it typically flags an oil change at around 7,500 miles. In Europe Honda issued bulletins to say ignore the variable service and just go on time and distance.

Do those detergents also make the "captured" particles small enough to now fit through the same gaps that they got caught in in the filter weave?No, they don't, another old wives tale that wants to be batted back to the perpetrator of such b0ll0cks.
It isn't true.

But at the end of the day we don't ever change oil on an Agri vehicle with out changing the filter too. I wouldn't change oil on a car without doing the filter too.
