Changing oil more frequently, will not void a warranty. However, not changing the oil @ 8000km or 5K miles is not good for the engine and not in accordance with established Hyundai service intervals.

Do so as often as you are able or can afford. Normally, 3K miles or 5000km is the established interval.

Yeah, I understand that :) But when car is under warranty it can be serviced only by official dealer to keep warranty, in my case I would like to change oil by myself between dealer visits (off course it will be off record and won't be in written in service book).
 
When I was in for a recall I asked them to change the oil, was at about 1500 miles. I'm not sure if they would have ultimately refused if I insisted but they strongly advised against it. Said I needed to leave it in for at least 3000 miles.

They had no 0w-30 in house so I didn't press on but thought it was interesting they told me it was a bad idea to change at such a short interval.

I know this isn't the case, and it hurts nothing to change early but that was my experience concerning the matter.

You can go in a get an oil change anytime you decide, either at the dealer, do it yourself or at another shop.

What you have in the VN at the moment is; a synthetic blend. Changing it, isn't going to do anything but remove any particulates the break in causes and assembly lubes.

However, get it changed again at the regular service interval. 3K mile oil change by-the-way is, the sever use schedule. 5K miles is the normal Hyundai Service interval.

Just a note that the service intervals in the UK or other parts of Europe (which I expect Interstellar is in, because his pic shows a Fastback N) may not be the same as what we have in NA.

You can do more frequent oil changes than the recommendation but cannot do less frequent.

Are you absolutely sure you cannot do work yourself or have it done by a third party shop?

Here in Canada, we can do DIY oil changes or have them done at a non-Hyundai shop and maintain warranty coverage, as long as the correct spec oil (per the manual) and OEM filter are used and proof of purchase is kept. I do all my own oil changes, keep the receipts and take a picture of the receipt with my mileage showing on the dash. Then I update my "service passport" with the mileage and date I did the work. I've discussed this with Hyundai Canada and the above was my conclusion.
 
The very first oil change should be done at max 3000km, optimal should be 1500km. Then every 10k mark.

Depending on how hard you beat your car around during your daily driving you should probably change it every 5000km.

I can only speak for the UK but Hyundai have said anyone can do the oil change aslong as they are VAT registered and use the correct brand and spec of oil and OEM parts such as oil filter.

You can also do a change yourself following the same guidelines.

If you use a different spec oil etc and say you spun a bearing and took it to Hyundai for a warranty claim, then can tell by doing an analysis of your oil if you've used what oil etc. It's upto the individual if it's worth the risk etc.

The UK service interval is 10,000 miles and nothing is required before that. I have changed the oil and filter at 5k anyway as I do with any car I've had. Change at 1/2 the interval.


Also, when you get the car, you get a years breakdown cover and If you service through a Hyundai dealer, then you get a years breakdown cover added on for upto the warranty end point.

:eek: 10,000 miles! I'm shocked that Hyundai would even suggest not changing oil & filter in a car for this long, especially in a GDI.

Good on you!
 
In Belgium the interval is at 15000 km. When you use your car on a track I would change it more often, but when you only use it as a daily driver with normal to spirited driving I don't see the point in changing it more often. You really think they would give a warranty for 5 years (unlimited distance) if they would think there was a possibility it would wreck your engine?
FYI: my last car was a Octavia Rs wich was driven just as hard and had to be serviced every 30000 km, never missed a beat. So, and I stress on this, for normal dayly driving, I don't see the point in changing the oil more often, but everyone is free to do it if it helps them to have their peace of mind.

The manual does state 10k as well but don't have access to that atm.

Well, then hyundai germany is either trying to rip us off or they already take into account that german i30N are being driven at higher speeds more frequently than those in other countries.

I believe I read that somewhere in an intervieuw with Albert Bierman. Sounds logical as Germany is, for all I know, the only country with unlimited speed on the autobahn, so the stress on the engine can be a lot bigger if you frequently would do long stretches at high speed.
 
At the dealership i work for in Sydney we use to use Caltex Havoline pro DS 0w-30 C2 which had a part number in the Hyundai Catalogue. 34282 20.

But now we have switched over to Castrol Magnatec Professional 0w-30 C2.
