Now i know that this topic has been done to death but i figure i might as well ask.

I looked down at the odo this mornin and low and behold its time for an oil change AGAIN.:eek: feels like i just did it last week.

So my question is basically this: do u think its completely nessacary to change the oil/filter every 5000ks or can u run it little longer depending on how u been treating it?

U know i value all opinions no mater how moronic they may seem:lol:

Hehe well that goes with out saying doesnt it. Last time i asked an aunty this question she said "huh what doesnt the oil just top itself up?"

I come from a family of car abusers.

My bro got home this morn when i was just pulling out to go to work and he gets out of the car walks round the front and opens his bonnett and puts his radiator cap back on that he just found on the floor as he pulled up. Now call me ismail but i think he was driving all last nite with no radiator cap on and he fills it when its overheating with cold water and wonders y it pisses water all the time sheesh :eek: this is the guy that has cracked 2 head gaskets 1 in a merc and another in an eb falcon from the same thing , drving with no oil or water in the car . *sigh*

Im pretty fanatical about oil. I do mine every 2000kms of hard driving, or around 3000 of not so hard driving. But then i dont drive it that much, so can afford it easier :P

I do it for peace of mind more than anything. Just like to know that the engine always has clean fresh oil.. MMmmm.

:burnout: :burnout: :burnout: :burnout:

(Motul 6100 synthetic ~50-60 bucks for 5 litres i think. Have been using Purulator filters, but changing to the Hard Driver filters)

Own ure own company do ya;)

Every 2000ks, thats nutz!!, especially considering how much u pay for oil.

I drive mine to work and dont really have the second car luxury so alot of the ks are done in traffic on just cruzin.

So u change the filter with every oil change

Jebus Boostzor, you couldn't have changed oil more than 8wks ago, 5000k already. Too many aimless cruises, eh? :) Oh yeah, tell your brother he's an assclown for driving around without a radiator cap.

SLY33, could you tell us more about Purulator and Hard Driver filters, including price and any reasons why they may be better than genuine Nissan filters?

I can tell with my 32 that when it gets to around the 5000 km mark after a service it is a little harder to start when cold or warm and doesnt idle quite as nicely..

I change oil/oil filter/check fluids/clean air filter every 5,000...

Have to do my diff oil when i service it on the weekend as well...:)

I've done ~13,000 klms in a bit over 2.5yrs (the time I've owned the car) I've done 6 or so oil changes in this time!

I change my oil based on how I've used the car since the last change, or on time (months) If I changed it based on klms I wouldn't do many oil changes!

Excessive? Maybe? But I'm happy knowing fresh Motul 300V is doing its best :)

I'd say 5k/6months is a good guide in most cases. Turbo engines are very hard on oil.

Change the gearbox oil after every track day?! Jeebus!!!!!

Transmission oil is different to engine oil. Most of the contamination in engine oil comes from the partial burning of it, plus it gets mixed in with fuel etc, all of which end up breaking down the rest of it.

A gearbox is a sealed unit though, with no burning going on. It only wears out as the gears squish all the oil molecules together and they eventually get separated and they don't lubricate properly anymore. You do tend to get some metal particles in the box, but most of these settle down the bottom and aren't too much of a concern.

My gearbox had never had an oil change when I got the car at around 85000, so when I changed it there was a LOT of metal in it. And yet the box was good both before and after without too much of a concern. You're only getting a few shavings after a track run, if you're running a good quality transmission oil (eg Redline) then I don't see why you'd change it after every track day unless you were racing professionally or something and someone else was paying for your oil.

As for engine oil, I change it every 5000 just for simplicity's sake, but I pay attention to the colour. It should end up a sort of dark brown/gold colour when I change it, I never let it go completely black (which it usually does by 10000). As long as it still has some of the gold colour left in it, it's doing well over 90% of the work it was doing when it was fresh. With my current driving habits the oil so far is still fine and it's almost done 5000 since I got it.

A good quality filter is essential, never skimp on that. A good quality filter should last for 10000, but what you're more concerned about is the size of the particles it lets through even when it's brand new.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
