It's amazing what an oil change can do

[Quasievil]

Dont forget your Air Filter also, this is a piece of kit that always gets forgotten about, and this does affect your oil.
Replace it or clean it very well................properly

[Eyegasm]

Christ. I must be pedantic....

I change mine every 3-4000ks

Or it's just that I dont want the hyobag to explode before I have finished with it...

A lot of old oil is always trapped inside the engine. Like in oil coolers etc. Some bikes as much as 30% of the old oil stays behind. Doesn't matter as at least you are adding some new oil with fresh additives.

The filter material itself is perfectly fine for every 2nd change.

ummmm. my bike takes 3.8L oil

with 30% left behind that means I should only pay for 2.5L when i do my oil change but for some reason.. it always wants me to add 3.8L to fill it up......

why?????

it goes from amazing to a nuisance when you have to do it every 1500km.

I said *some* bikes. The oil cooled Suzuki bandits were a classic example.

And is that 3.8L the oil capacity after an engine rebuild...???

You put 3.8L in when you do an oil change.

In your owners manual it will state oil capacity after an engine strip and rebuild. That will tell you how much of the oil you are actually changing when you do a change.

and yes....ok seriously..

3.2L without oil filter
3.8L with oil filter.

and it takes exactly that every oil change.

But why NOT change the filter?

Too much of a tight-arse?

That's the oonly reason I can think of.

Could be lazyness... A pain to take off faering etc?

you don't have a liver transplant everytime you get a blood transfusion do you

There should be a 3rd capacity. The amount of oil after an engine strip down. (maybe you would need to look in a workshop manual for that)

Wow, that's way out there BIll!

So why not every fourth oil change then?

[T.W.R]

There's three different oil amounts generally

ie: as per a Bandit 1200

Oil change = 3.3lt
Oil & filter change = 3.5lt
Overhaul = 4.6lt

As you say roughly a 1/3 variation from a dry rebuild

[imdying]

Yup, probably another 300-400ml more than 3.8l.
