New filter every oil change ?

[BanditJeff]

I've always changed a filter with every oil change, for no other reason than i just always have done. Yet Suzuki recommend changing the filter only every third service/oil change.
I know the cost of a filter is only a few quid but i'm interested in the fact that everyone i know changes the filter with every oil change......can the small amount of old oil in a filter really contaminate new oil ?

i do it every 2 or 3 if i forget the filter.

Every other I do. Generally do that with all my bikes/cars.

A filter for my bike costs about £3, oil about £10 so £13 it costs me to service my bike.

No point not changing the filter.

Hi

Filter is there to catch the rubbish, and as it gets blocked more and more of the oil will bypass the oil filter. Filter is a pretty nominal extra cost when doing an oil change so I would change them every time.

But I do have sympathy with those who have to remove the exhausts to get at the oil filter.

All the best

If I'm doing the oil change at the proper service interval(s) I'll normally alternate changing the filter...
but if the oil change is overdue, I'll change it every time.

I've done it with cars and bikes over the years - (following my uncle who was a keen amateur mechanic, as well as doing itprofessionally for a number of years).

The way i see it is, an oil filter is there to stop shit getting into all the oil gallerys on your bikes engine. I change them everytime i service a bike unless told not to in this case i talk to the customer recomending a new one and why, 9/10 times they needed it doing... 4000miles ago aswell as the god dam oil. Black piss is not oil.

No one knows for a fact do they...... its all just assumptions and guesses.

I change filter every time, always have done, bike, car, van.
It isn't worth risking it, even thought the risk may be very small indeed.
I always use genuine filters too, after twice having problems with pattern parts.

Usually change filter too but do occasionally go every other oil change. For example this weekend i gave my shed a small spring cleaning and discovered i had enough oil left in one container to do a change. Didn't have a filter to hand so just changed the oil and am not in the slightest bit worried- will do it next time.

I'd s most enthusiasts who look after their own cars or bikes will probably end up changing oil/filters more often than specified in the handbook any way so chances of a filter becoming ever getting clogged are slim.

I do a new filter each time - kickstart says to

In all seriousness though seeing as it is a few quid I just change it each oil change on the "while I'm there basis". I also try to do 1000 or 1500 mile oil changes, totally uneeded but it makes me feel better .

Also, if you don't drop the filter, then you aren't changing ALL the oil, are you?

Canister types anyway.

Hi

I am afraid I would be more inclined to see service requirements as being the result of the engineers recommendations being hammered down by the marketting departments want of a cheaper service schedule to make the bike appear cheaper to run.

Just checked a couple of workshop manuals here for the 1200 Bandit and the GSXR1100K. Both basically the same engine. The GSXR lists the oil and filter to be changed with every 3500 miles. The Bandit list the oil to be changed every 3500 miles, but the filter only every 3rd oil change.

Oil has improved a bit in how long it lasts, but no change in how long they recommend keeping it in (although that could be due to contamination, and a built up of acids in the oil). But not sure that the filter system has changed at all, nor the generation of debris that sits in the oil and gets caught by the filter, yet that is now far less frequent.

Although the cynic might say that an early GSF1200K probably had the oil holes in the pistons drilled in the wrong place so most of the oil and debris would have been burnt off long before it had a chance to affect the filter .

All the best

i did find it odd that my gsxr only requires a filter change every 3rd oil change, fook that for the sake of £5 i'll just change it, only 1 fairing to remove
