sorry if this is a repost.....
please don't tell me the kms..... i know that

but i was wondering if the engine oil is supposed to stay yellow?

i did my break in till 1000 kms then let the dealership do the whole thing.....

right now i'm at 2000 kms, and the engine oil is just BLACK...... but still liquid

so basically i want to change the oil and filter etc.

the reason so is that....... during the break in, i was babying it? but now i'm riding it hard...... so the pistons....

break in= 1-8rpm
now.....= 1-13rpm?

so maybe now it rubs the 8-13rpm place.... so it gets dirtier faster?

so my question is..... should i change my oil tomorrow..... considering it's black, and is black normal? usually it's yellow for me

and yes i'll do myself.... trying, seems fun

 

[kriestpuncher]

the oil turns black pretty fast, doesnt take long. dont worry about it. just watch out for chunks, then your f**t.

 

[REVELATIONS]

Its the same as your cars oil. They both turn black pretty quick after an oil change.

so maybe now it rubs the 8-13rpm place.... so it gets dirtier faster?

The engine rubs the same places at 13K that it does at 8K. It may rub them a bit harder is all.

Since your bike is new, I wouldn't say it's a bad idea to change the oil at the 1K mark and the 3K mark. How you treat that engine for it's first 5000km can significantly affect it's life, but this will probably be more of a consideration for it's second or third owner, not you.

I'd change it.

 

[mascu]

so it becoming black..... i shoudln't worry about it then

alrite then.... i'll change when it's 3k, not today

2 more weeks to go i guess

thanx for the feedbacks

change it at factory recommended intervals. doing it too soon is wasting money.

for a new bike, in general, oil change every 5000 km, filter change every 2nd or 3rd oil change. it's in the owner's manual.

 

[SkydiveSonic]

I change mine around the 3k mark (ie. half way to next service).

 

[coolio]

I change my oil at 5-6k. I'm using motul 5100 $$$$. If I were using castrol gtx, I would change it at 3k.

 

[Stewy]

I change mine at 3k and swap in a new HIFLO filter as well. I am running the Amsoil 10w40 full-synthetic.

paraphrased from the 2003-2004 gsxr 1000 service manual periodic maintenance table:

engine oil: replace at 1000 km, 6000 km, 12000 km, 18000 km, etc....
oil filter: replace at 1000 km, 18000 km, etc.....

changing your oil every 3000 km is pointless and a waste. changing your filter every oil change is pointless and a waste. a dirty filter will actually filter better than a brand new clean one.

read the manuals.....

I can't agree with you more doug!!! Why burn your money!!!! You don't need to second guess these engineers!!!

Really? That's not overly clever. Current oils have a V good and annually 'improving' additive package..that is The heart and soul of a decent oil... it will last perhaps even 10,000kms. Gone are the days of actually needing to change oil at 3, or 5000kms. Oil turns black from hi heat Or in old worn engines, which do it immediately as combustion materials get by worn rings.
Fresh healthy engines wil,l with decent oil stay 'golden' for several thousand Kms. Given the designed in longevity of current oils (all of them with a current API classification) Filters on the other hand, are the items that should be changed frequently. as in BETWEEN scheduled oil changes.. But Hey! why would you want to spend $5 needlessly.
PS: the "dirty filters, filter better" is simply a statement from the truly uninformed.. don't even think about believing that idiocy.

please explain why FACTORY recommended filter changes are 2:1 and 3:1 to oil changes then.

that page explains how the best filtering is obtained mid life of the filter.

is it still idiocy?

I can't agree with you more doug!!! Why burn your money!!!! You don't need to second guess these engineers!!!

Because the engineer's spec is only designed to get your bike through the amount of miles a certain percentage of owners put on during the warranty period, plus a reasonable safety margin. No more, no less. The accountants run the numbers, then tell the engineers to spec to that percentage. They do want to sell you another bike after all.

Oils break down as soon as they're in use. The long chain molecules that make oils "slippery" (and which synthetics have a much more consistent amount of) break down into shorter chains, which lubricate less and less well over time. Similar breakdowns happen to the various additives manufacturers put in their oils to help them last.

Then there's the contaminants. Over time, oil gets byproducts from combustion and the atmosphere in them (i.e that black shit in your oil you see). Water condensation can be a real problem, especially for bikes that don't get heated up well, or get stored for long periods of time without being run. That's one of the reasons why oil change intervals usually also have a time component to them as well.

There's no harm in changing oil more frequently, except to your wallet. And that may pay for itself if you hold onto the bike for the long term. I've seen a lot of high mileage engines that were well taken care of. I haven't seen a lot that were abused from day one and didn't get frequent oil changes.

Mine says to replace the filter same time as the oil. So not all factories recommend that.....

Let me give ya’ll a lesson in oil change intervals: The 18,000km your manual says is not because the engineers say it’s the best for your engine. It is said because the manufacturers wanna sell bikes. If you read the manual, it also says to do it at that (18k) if you only putt-putt around at low RPMS and no dust, and no nothing. If you actually ride your bike it says you can easily cut that time in half. That is the way they protect their asses BTW…..

Also, the reason your oil gets black is because all engines (some more than others) have blow by…it is the carbon from the burning gas in your cylinder that turns it black. The higher rpm you go the faster it turns black.

Synthetic oil gets contaminated at the same rate as non synthetic, thus it becomes abrasive in your bearings. I agree however that non synthetic oil turns into gas faster than synthetic. That said, I would change both at the same rate.

All this is true. I have been around the automotive industry for a number of years and have seen little things that caused all us mechanics to raise an eyebrow, such as: Volvo taking away the tranny services on the 850’s so they could financially compete with BMW over a 5 year maintenance period… (Like when customers would come in and ask how much for the car including all required maintenance over a given time, like say: 5 years)… clearly the factory doesn't give a shit about how long your vehicle lasts as long as it makes it past the warranty...come on, think about it!

Sorry Doug, but oil filters are not like air filters, they don’t filter better when dirty. In fact tests done show that a dirty oil filter contaminates your oil hundreds of times faster…now that can’t be good.

When to change oil? It is never a waste of money to over change oil. Make sure you recycle it properly and it’s all good. Engine parts will always cost more than an oil change.

My philosophy: I over change oil, however, I don’t use synthetic, instead I use a good non synthetic name brand. I change my filter every single time. When breaking in a new bike, much like breaking in a new girl (gotta keep it lubed)-- I change the oil often (like 3 times) in the first 1000k, and then go to every 3k.
