I don't. I change at 10,000km.

But your interval depends on the oil you are using, how hard you drive your car, what kind of air filter you use and how rich your car runs.

5,000km is a safe bet for most cars but sometimes overkill for others.

Well my car is completely stock, Synthetic MOBIL 1 oil and I dont really drive it hard, so yeah if its not really necessary then Ill wait till it hits 10000km.

Dont really know the maintance of a turbo car hance this is my first one, for the lude I just change it every 10000.

My car servicing people told me that every 10,000kms is ok for my car and its a stock r34 gt-t sedan. So far it has done 7000kms so far and no issues so i think it is ok.

But I have read alot of other people mentioning 5000kms on the dot but then again I spose its up to the owner as there appears to be nothing written in stone on this.

My GTT have nearly done 5000km since Ive first import it, dont know if I should change it soon or wait till Ive done 10000. Just wondering if the majority of you guys change your oil every 5000km?

It actually depends, try to get hold of a UOA (used oil analysis) kit which someone here mention for $40 a shot. The analysis will tell you if the oil is good to go or not.

I have always changed the oil and oil filter at the recommended intervals and use the best oil that I can afford.

I see this as good insurance and over the years it has paid off as every engine that I have pulled down has had minimal wear compared to what would be expected for the age.

I am currently using Motul Chrono 300v in my Skylines and after 5K it comes out cleaner and in better condition than most oils are when they go in.

I remember reading a UK thread years aga and everyone there was doing the same debate on the 5000 change...most people did do the 5000 change but they're in miles so realistically, that's every 8000/kms.

The '5' seems to be a magic figure.

..so anyway, i guess if you do every 5k, you will be damn safe, just have to figure out for yourself if it's overkill.

(I personally would go for 10k but thats me)

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
