How often do you change your oil ???

Hey guys, searched but couldnt find. Just curious how often do people change their engine oil. Should it be the same for full-synthetic and regular ?

Just to have an idea

Im running full-synthetic Amsoil

I change it every 3000-4000 km

Ps. In the manual it states every 6000 km
 
I'm predicting the masses will say.

"Open manufacturer's operating manual. Read what it says for oil changes. Do that"

There is no need to do it at 3-4000 km, with better oils and better engine technology really engines could go longer than 6000km between oil changes.
 
True, I think it should also depend on your riding style and conditions. I tend to change earlier if I've seen a few high temp situations like when I got caught in traffic in Montreal on a sweltering day and saw the temp hit red. :(
 
5k ish more or less just because its easy to remember that if the the bike is at #5### or #0### I should be thinking of changing it.
 
A related question: would you change full synthetic oil in the bike at the end of a season if you only rode 2,000 km in that season?
 
4k for non-synthetic and 6k for full synthetic.
 
If you want to have an idea of the condition of your oil, you can buy a UOA kit at Napa for $12 for the basics or $18 for the full test (inc. TBN). Go for a ride, come back, suck it out of the dipstick hole if available, without letting it idle very long, stick it in the pre-paid box, voila, you know the condition of your oil, bearings, etc.

In my 09 R6S using Amosil's MCF full synthetic motorcycle oil and their "long" premium CAR oil filter (EA15K13) I got right to 9000km's before I started to get any measurable degradation in the oil!!! So I did my changes at 10k and Amsoil did their own test (which I don't really trust, lol) when I changed my oil, and they said probably around 14k I should be changing it!! CRAZY!

6000km is fine unless you notice a change in the bike. I start getting missed/notchy shifting at the 4000km mark so that's where I change it (I use full syn).

Yes.

Winter = change in temps = condensation in the crankcase + combustion by-products in the oil = weak acid solution and possible bad things for seals etc.

i just change mine as one of the last things before i put the bike away and then I don't have to worry about doing it in the spring.
 
2000K on the oil, I wouldn't change it, just make sure the last ride is 30-40 minutes long,
you want to get the oil up to full operating temp before you park it.

Reason being, the moisture and all the other crap that is in the oil and crankcase will burn off
with the high oil temp which is usually around 220-230 deg f

Thanks RonnieRev, that makes sense.
 
I just got a bike with 2000 KM on it, first thing I did was change the oil, since I don't know what the previous owner did/didn't. After that, every 5000km sounds good for oil and filter.

4000km? Yikes! Which oil filter you running, and which "full syn", cause you know most synthetics are not "full syn" right? :)

3-4k, i run semi synthetic and oem filter.
 
Wow, some ppl are misinformed.
I did some tests on Rotella syn. at 10k. The oil still had TBN in them. Could've run it longer.
Also did tests on Amsoil at 10k. Still had TBN in them.

I had a thread about those tests a while ago

Some bikes burn oil quicker than others... and depending on how you ride...

The GS500F is known to burn oil hard from factory, and I had a +6 rear sprocket on. I would constantly be riding past 7500rpm if I was on the highway, or spirited (for me) twisty riding; which is 85% of my riding.
When i would change non-syn every 4000km, which was the point where the bike felt like it wasn't running as good (mostly the already slippy tranny would start slipping a lot more), the oil would come out jet black.

Full syn gave the same results around 6000.

I would say the only way you can know for sure is if you send out oil to be tested. It doesn't cost more than $25 and you learn alot what your engine is doing

I'll keep that in mind for my next bike.

Where would I send it go? Got a link or anything?

If you go to Napa they sell an oil test kit, $12 for basic or $25 for TBN. Comes with a container, instructions, and pre-paid stamp for it.
