Change oil but not filter?
#11
They say oil is good for 3 months or 3,000 miles and synthetic 7 months or 7,000 but then again who are "they?" The detergents in the oil tend to break down after such a period of time, thru heat cycles and such and mixture with oxygen. but as for the op's question, change the oil leave the filter, the filter is there to catch contaminates which the engine shouldn't have produced any since it hasn't been driven!

Worth changing the filter too? Or should I just dump the oil and put in fresh stuff?

I change the oil in a new car, but then again, it sits there for month. Then again, you buy it off the shelf, it has sat there...for who knows...
No worries, but change the filter like they have said above.

You are very correct in mentioning about heat cylces and the like, but since the oil has just sat there in a pretty sealed sump, it'll be absolutely fine!
Really is no need for you to change unless you have money to waste.
Just keep an eye on the oil level (as always).
If you start to consume lots, the oil has sheared and it's time to change.
I use Castrol Edge (I believe it is badged as Syntec for you guys) and it has offered the best results for me compared with Silkolene Pro-S and Castrol Semi-Synth.
However, there comes a point after about 4000 miles where it starts chewing through oil all of a sudden.
It's at that point I know to change

I thought about changing my oil the day i brought out my car and i was under very similar circumstances, i just drove it, but a few thousand miles on it and no problems, i wouldnt worry to much.

Oil never wears out but it does become contaminated, diluted and the add pkg loses it's positive properties because of these factors plus through volitility. It would seem that a relatively easy test could be produced for consumers, but it would probably have to be done through a major oil company and this type of info is not conducive to selling oil to consumers who (in many cases) do not need to change oil every three mo. or three thousand miles. If oil did require this frequency and low milage, would'nt the oil companies be quick to produce a product to prove that oil should be changed at this frequency?
Keep the public in the dark and guessing, and they sell more oil. Its just good business.
