that and the bang bang puter, had to of upset the bearings

no i dont think knock was only ever 30 odd at bang bang, it was definitely already damaged before then

What type/brands of oil are getting ditched at 5000Kms?

i used to use Nulon fully synthetic a lot of people go for motul

its to do with synthetic oils passing by the rings and burning out your exhaust so when people say "oh it doenst burn oil' there mislead

i used to think the same 10000 is fine with synthetic but better safe than sorry

there is also a better reason but i cant explain it as good as i was told it :P but thats the gist of it

The reason I ask is, in the time I did 10,000 Kms I didn't need to top up the oil level at all. When I drained it, it was of course dirty coloured but certainly didn't look contaminated (ODO now reads 119K and I've never had it past 5.5-6K RPM).

A few people I spoke to suggested using Motul 8100 or 300V and changing at 10,000 simply because the oil is of a much higher specification than that used in 1995 when the engine fired up for the first time in the Nissan plant. I don't really know, this is my first turbo car!

keep in mind that 2 things stuff up oil....fuel & heat.....hence why regular changes in summer are handy not to mention tired motors need the oil dumped more often cause of fuel by-passing old rings

EDIT: and as Adrian said, peeps that boost more than others need to be more regular also (because of greater fuel by-pass under boost)

One that was daily driven to work, running stock boost should though..

My 20 only lived to about 105,000 before she died. Car was pretty much stock. Sometimes they just die young :P

I use fully synthetic and change it at 10,000, is there any particular reason why RB's need changing at 5000?

I thought it was for the turbo's. Turbos aren't supposed to like contaminated oil, wears out the bearings sooner.

And here's another I heard, that all these "race quality oils" we use dont have any detergents in them and cook mega easy because they are designed only to be used for say one trackday and then be thrown away...

We need oil Mythbusters :D

Chad, I guess mine fared a little better than yours then :P

    • The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
