For that budget, go for Delvac 1 5w40. 5L should be enough for RB25 rite

Yep, the RB26 is about 4.75 litres total. Takes about 4.5L first, then when you start the car oil fills the reserviors and oil filter so the sump needs a bit more.

oops sorry

the car has done just over 70k

I'm a bit of a lead foot

Driven Daily..small trips... with roughly 100k trip a fortnight.

Just drove it over 2000k across the nullabor with no oil consumption.

Oil is black :no:

Doing oil change this weekend :happy: With a bit of help :)

I know it might be a bit late as you may have done your oil change but,

I was running castrol 10w 60 and changed to a castrol 0w 40 best change i have done. it starts better and the motor runs cooler by about 5-10 degrees less. What i have read from this forum is the 10w 60 is mainly for high kms and race cars.

stagea girl. just buy a 4 litre, and a 2 litre of the 300V. yes it's more expensive, but it's a far, far better oil and i think it's better value when you consider the difference. plus your first oil buy will be expensive (need 6L) but then next time you only have to buy 4 :P

  • 3 weeks later...

Castrol EDGE is just rebranded Formula R. Not a single word was changed in the specifications in the PDS's from what I've gathered. But how knows, they might be different.

But yes being synthetics (well API Group 3 base anyway), they are much better suited to our cars than a semi or mineral oil. I still would say they are not as good as Mobil 1, judging by their specifications. Only their 0W40 would be the exception which would be comparable (being API Group 4, ie PAO).

I've trialed EDGE 5W30 in my car as 'flush'.. seems to be working well so far.

man all this oil talk makes me feel guilty coz i just changed my oil with repco brand semi synthetic 10w40 thinking it has the same weight etc.

what do u guys think about that oil?? (anyone here actually ever used it, i know its pretty cr*ppy)

eng: rb25det(turbo back zorst, pod filter)

change interval: every 5k

driving style: granny street driving (occasional heavy foot)

oil consumption: b/w H and L from H after 4k

from what i've read so far Mobil delvac1 and Motul 300v is real good but a bit pricey, so im going for value and choosing Castrol Edge 5w30 for my next oil change, is that good enuff?

many thanks in advance

aquariuz6, yes IMO their 0W40 is the best out of the EDGE range and I would recommend it.

vbdotnet, well being Repco, what can I say. Will do the job for at least 5,000km intervals. I'd give the EDGE 5W30 a go on your next change. Devlac is too hard to find (although its easy for me) and 300V is a bit overkill for your R33 with the usual mods.

im uainf Mobil 1 15w/50. And im a mobil man.

please note Castrol do not make their own oil they sub contract it out. Well this info is about 8yo so i dont know they still did the same thing or not. Castrol do not take out the carbons in the engines out . thecarbons stays in the engine thus when you switch from castrol to mobil the engine shits itself. cos mobil oils takes the carbons out

Devlac is too hard to find (although its easy for me) and 300V is a bit overkill for your R33 with the usual mods.

Yes Delvac must be extremely hard to find if no one has answered my question as to where I can find it in Melbourne that was asked twice LOL :)

After lots of reading and searching I'll be going Delvac 1 next change, especially if I can get it at a decent price.

The old motul 8100 5w40 has jumped up in price it appears, I used to be able to get it for $60 now its jumped to $69. :)

On another note:

Spotted Pennzoil Platinum with its little 'made in the USA' sticker at the local repco store.

Interesting find.. First time I've seen it in AUS.

PP got pretty good review over in BITOG, it make up of mostly group V (not ester but EOP) base stocks. If it's cheap just use it.

    • Apologies for the long post, but needed somewhere to lay out the entire timeline of events and actions taken:   I've got an 89 GTR with a R34 RB in it. It's been running great all year, driven probably 500KM in the last month. It's not my daily driver, just a weekend fun car.    Build info: R34 RB26 - HKS 2.7 stroker kit, HKS adjustable cam gears, HKS turbo upgrades, Trust intercooler, R34 factory DENSO 440cc injectors, JUN chipped/tuned R32 ECU. All of this work was performed in Japan back in 2019.    Thursday 10/2/25 - It's a nice day and decided I'll drive it to work, I start it up in the garage and I notice it took a few extra cranks and sounded a bit funny. I figure maybe it was just because it was a pretty chilly morning. I pull it out into the driveway to warm up a bit before leaving. As I leave the driveway, it feels very off and sounds like a misfire. I pull it back in the garage to deal with after work and take the daily to work. I was able to diagnose it as a cylinder 5 misfire with the old spark plug test (unplugging each plug until a sound change with the engine running). I take off the whole ignition system, ignitor, plugs, spark. *Important note, it is still on the R32 ignition system with the separate ignitor system. I test each system with a multi-meter and nothing presents as a smoking gun. I put it all back together and it starts up no issue. I go ahead and order the PRP R35 ignition conversion kit. It should arrive today (10/13/25)   Friday 10/3/25 - Another nice day, car starts up great and drives great all day. Very pleased that everything seems to be OK   Sunday 10/5/25 - Decided I'll take it to play some golf, load up and drive to the course about 25 minutes away. Drives wonderful the whole way there, I pull in the parking lot and the engine completely comes to a stop. I do not recall if it sputtered at all, but just remember all of the sudden the engine was off. I roll it into a parking spot, try to crank it back on and nothing.  It'll crank and crank and not even try to start. End up getting it towed back to my house and push it up into the garage.    Items I have checked: Fuel in the tank Fuel Pump relay Fuel pump fuse  Spark Plugs & gap Coil packs Ignitor    I know the cylinders are getting fuel as the plugs smell like fuel after a start attempt. I tried spraying starter fluid into the manifold and cranking and not even a sputter.    I decided to do the live CAS test (removing the the CAS, ignition on and spinning the CAS stalk to see if the injectors pulse and spark is active). All of the injectors were pulsing and I have spark at the plug. The half-moon end of the CAS did seem very loose, I'm not sure how much play is supposed to be there, but it was more than I expected. There was no in/out play of the shaft, just the tip end that is pinned on had quite a bit of play.    CAS Play video   When I put the CAS back in, I stupidly did not re-time the engine. I know I need to do that tonight, however, I do not think it will start given it seemingly was not the issue. My plan is to do the PRP R35 coil kit and retime the engine at the same time.    I plan on ordering the Haltech Nexus Plug-in ECU once they are available again, but ideally would like to get this sorted before firing the parts cannon at it and potentially adding more variables.    Anything glaring that I am missing here, I'm a bit at a loss?          
    • Get it on a dyno. Get something logging Consult. Run it up and find out what is causing it.
    • Looking for a plenum for rb25 de+t neo  Not looking to push much power maybe 300kw at the wheels, is there much difference in flow for Freddy “Greddy style” compared to original Greddy or options like Proflow or Otaku garage?    I won’t be porting the de Neo head for now as I think it’ll be fine 280-300rwkw but appreciate the help and any experiences anyone has between them and any advice. Thanks  Looking at this plenum for now below 
    • engine wise almost no mods: stock ecu Greddy front mount intercooler Greddy forward facing intake w R33 TB stock fuel system, stock injectors, rail etc. Kakimoto racing hyper 3 inch exhaust system Apexi intake filter New NGK –R BCPRES (.8 gap) plugs  
    • Nice one @Pac - looks like a fair few 1600's there!
