the castrol is a cheap oil. group III base. if you want a good oil you have to pay more for it. it's that simple. the castrol you pay for marketing, motorsport involvement etc, and a bit of your money goes to developing oil, but it's still a cheap oil, and in my view poor value. but again its' a simple equation. good oil costs more than worse oil.

personally I think if you care about your engine and like to give it the old spanking then a IV or a V is the go. I use motul chrono 300V. costs a lot, but to me it's worth every cent. oil is one of the most important ingredients to a happy car. in my mind it's right up there with tyres as the biggest thing people underspend on. I say you can never spend too much $$ on good tyres, or good oil.

agreed! Group 5 all the way....

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...

I am due for an oil change in about a month or so.

My rb25 will have 174 000 kays on it when its next due.

What oils have those of u with high kilometre engines out there used?

My intention was to use Shell Helix Ultra again.

There seems to me too much bullshit surrounding what oil is the best... you guys are seem to be confused as well. I think Ill just stick with Castrol 5w-30 and be done with it. As long as I service it regularly and dont punish the car on the track I should be ok.

No confusion here.

I simply refuse to pay for a so called synthetic as you are at synthetic prices.

Motul 8100 5w40 for this very reason is an excellent value motor oil when you consider its a grp 4 'true' synthetic when the bottle of castrol next to it is roughly the same price if not more where I shop.

Also... Monitor your oil usage with that castrol 5w30. :thumbsup:

Hey man, after reading a lot of this stuff I went with royal purple to start with from performancelub.com (mobil 1 is the same price). It is a reasonably good oil i think for a good price. I am planning to do a sub 5000km change on it again anyway to clean the engine a bit, and I'm planning to use the mobil 1 this time round. Then after that I think I'm going to bite the bullet and use the redline but from what i've heard, this oil could probably be safe for up to 10000km so I'm going to look at changing the redline every 7000km when i start to run that.

hope that makes sense.

p.s. you can read and read and read, but generally there is no real 'cheap' way to run 'the best' stuff. if you want the best, go for redline. if you want the next step down, go motul 300v, if you want the next step down, go mobil 1. if you want the NEXT step down, sell your car and buy something that likes cheap 20w50 :whistling:

I paid 48 bucks for the bottle of Castrol 5w-30. How much is the Motul 8100 5w-40?

Ill check how much oil I got today :P

No dramas mate. Royal Purple, i will look into it.

And i do realise that skylines and cheap never go in the same sentence. I spend big on everything else so i aint gonna skimp on something as important as oil :thumbsup:

yeah especially in an rb...... it will do its own oil changes :P

I tried the castrol 5w30 a year or so ago; motor had probably done around 20,000kays. I found it used oil with the castrol 5w30, dropped the motul 5w40 back in and not a drop.

Was using Mobil1 10W30 and found it caused a lot of noise from the lifters

Hows your oil pressure? :S

I'm running royal purple in my gearbox and engine, and have no worries at all. It does the job with no problems, and I think the idle is smoother, but it's hard to say with these things. Also cold starts are fine, so full endorsement.

If you're in melbourne, just email royal purple directly, and they should be able to sell you some from the warehouse. I was looking at a group buy at one stage, but there was not enough interest.

From what I've been told, Redline is better, but it's also much more expensive. If you're racing hard, go with redline. If you're driving normally with the occasional squirt, well, I picked Royal purple for that reason, with the bonus that if I spring a leak, I'll know about it due to the unique colour on the driveway.

Checked the oil tonight and it was still up to F. Car has done 6500 KMs since last oil change. Im planning to do an oil change (same oil Castrol 5w-30) at 7000 KMs.

      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.

      ECU sees many times the speed than speedo does (R34 swap)

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
