As BB says, horses for courses. I am more regularly at 120-130 degrees towards the end of a session whereas he is more around the 105-115 I'm guessing.

spot on. On track I'm up around the 115 mark at max, but oil pressure is still a steady 6 bar at anything above 3,000rpm (which is all the time).

I wouldn't worry too much about winter oil/summer oil your car pretty much runs the same temps summer or winter, maybe water temp get's up a bit in summer traffic. but even startup temps would only be 10degrees difference at most.

maybe try the 10W40 one trackday and see what the oil pressure is like?

Sorry I meant 15w50. It's the 300v Competition. I have been thinking about using the Chrono for winter but my car has always run fairly hot so I appreciate the extra thickness at high temp. I probably should use a better quality oil cooler but the one I have works ok and the 15w50 gives me the protection I need.

I do notice quite high oil pressure when cold and am particularly careful when warming up the car because when using a thicker oil like this I think the turbo is more suseptible to damage due to lack of oil flow. I never boost at all before the water is up to temp and would be lucky to hit 0.3bar before the oil temp has risen.

Thanks for the explaination.

I do use the 15w50 300v Competion oil, for my R32 GTR. Just Jap use it for thier GTR's that run in Targa and seems to be good.

I spoke the guy at Green Goanna and he said that he does not stock the Motul brand oil. But he suggested to use Shell Helix Ultra 15w50 for $205 incl GST for 20L. The Shell oil is used in alot of the rally cars.

Has anyone used this oil?

Cheers

Guys try Harold at performancelub.com.... Royal purple is 10.90$ for a quart (946ml)... this guy imports his stuff form America.

he is located in Melbourne, but even with postage he is cheaper then most places.

Cheers.

I picked up some Mobil 1 0w40 for 54$ (i picked it up though).

    • I have multiple bottles in a shed that gets hot, and I'm in SEQ, so it's humid. Maybe we test their theory... Anyone have a system to accurately measure moisture content in oil?
    • Yeah, that and throwing away opened, part used, closed back up bottles has got to be bullshit. Brake fluid sits in not-very-well sealed master cylinder reservoirs for literal years and keeps working (albeit we know we should flush it every couple of years - it actually still works). Anything kept in a bottle in the shed with a tightly capped lid has got to be a million times better than what has been in the car for the same length of time.
    • Wait, they're claiming UNOPENED fluid has a shelf life of only 18 months?
    • The plan is to get it out of the shed. The reality may fall some way short. But hope is as cheap as despair as they say. Will go a wide band I think. The coils are ok so maybe I’ll miss the $1500 on the R35 coils etc. Im still on the fence about a trigger kit. The HKS one looks nice ($1k) - not sure how it works with the Link or if Link prefer something else. Oil pressure is fine so I’m not that concerned there. Fuel pressure I’ll have a think about. The IAT got changed for the Link anyway as the old RB26 ones were really slow reacting and pretty poor. The Power FC just worked. Wasn’t terribly refined but it just worked. Probably made a mistake replacing it really. E85 isn’t available locally - it is 100+ kms away which puts it in the too hard basket. Lastly I understand Tunecorp in Perth are pretty good so was probably going there.   As for turbos is there are new age -5 drop in replacement? Turbos have come a long way in 20 years, everyone is big single which is fair enough but I prefer the old school complication of twins. Wasn’t chasing more power (well, not much more) but more efficiency would be ok.
    • I thought I'd share this....the shell is non genuine but they found or built a lot of the genuine parts. Plus, it is by far the best colour scheme of those years, the winfield once was particularly shit https://www.v8sleuth.com.au/written-off-inaugural-godzilla-recreated/
