Any brand will work fine, some just last longer than others. I still believe you are better off using a cheaper ($50) oil and changing it every 5k rather than spending twice that and trying to strin

Royal Purple 10W-50, warm it between your hands for a few seconds then apply it to the area at the base of your shaft between your balls ..about as valid as any other opinion in this thread

F1 still use monograde 10 weight oils, hence the need to get the engine warm before starting it. Nothing stone age about it...

Your oil getting black is from the detergants 'cleaning' your engine, you certainly wouldn't want to be getting black oil just from blow by.

If you change oil only every 5,000km's it should be slightly black, by 10,000km's if it aint black I would be worried, either the engine is impossible clean or the oil aint cleaning sh*t.

I think Mobil 1 would contain aleast an average amount of detergents, it recommends on the back of the bottle for GTR's i think,

Actually the oil I drained out was exactly 5litres. And its the first time I've changed the oil since it came from japland

Checked the dipstick and it seems to be fine

who says to use 3.4L? that would be on the low mark on the dipstick surely...

Personally i fill mine a bit over full , upto the H and thats 4.5L

Seems Chequered and Racepace are using Catrol Edge 10W60 for track work. I've got an oil change coming up and my car does mostly occassional street driving but will see the track from time to time. What's the latest thinking? Performance Lube are suggesting 10W40 Royal Purple, citing with group 4/5 synth oils 10W60 is thicker than it needs to be. I'm running a 310RWKW RB26 with extended sump and oil cooler.

Where is recommended to buy the Catrol Edge 10W60 if it ends up being the go.

Keep it simple for me guys.

Thanks.

RP 10w40 would be my oil of choice after the Edge (which is easily bought from most parts places and cheaper).

It's hard to judge without UOA's or filtergrams tbh, though I did see a car on another forum where they changed from Edge 10w60 to Penrite 5w50 and ended up with a lifter dragging on the cam and scoring a lobe. That was on an aftermarket cam with a fairly aggressive ramp rate though.

Mine goes in for a service tomorrow, so should have the sample off for testing within the next few days.

As recommended by Racepace iv been using Edge 10W60 for many years on my stock rb26 with 290rwkw without any issues, mainly street duties. Now same on my forged engine. They know their RB's!!

Buy it from repco or autobarn wherever is cheapest.

I would of thought using a light oil like 0-40 for street duties and a thick oil 10-60 for track would be sensible, and dropping the oil after each purpose is fulfilled, im guessing racepace wouldnt build the tightest engines if there built to be thrashed around a track, originally the 0-30w recommendation must of been for a tight motor out the factory.

My motor was stock on my last gtr and still ran the same oil as many other gtr's without any issues. My friend owns it now pushing same power 5 years later. Most gtr's are modified also which also has to be taken into account, factory recommendations go out the window. Besides these are engines designed in the 80's, not exactly modern tight engines.

Anyway I just listen and trust what they say, I'm not gonna second guess their knowledge.

Sounds like good advice there James.

Opinions are like arseholes, everyone has one. Try a few different grades and see/feel how your engine responds Flavzz.

Thicker oils will feel more lethargic until the temps get high but will offer more protection for the track. They will also take longer to drain back to the sump which is a common RB issue.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
