Hi guys

I do change my engine oil every 5000k with Motul-turbolight 10-40. I am planning to go with Castrol magnatec 10-40 with every 3000k oil change; just want to know which method is better...........

Engine: RB25DET Series 2 with 91000KM

thanks in advance :)

personally i do motul turbo light 10w-40 every 4-5k. and i drive it pretty close to granny spec.

Turbo light is a full synth oil for aus standards (78% or more), however they don't publish it on the bottle as its a euro brand and they have very strict laws. i found that according to the rating of the bottle the turbo light had higher synth % that some full synth pentrite oils.

I agree that its how often you change it, though! not how good the oil is. Although i reckon that it takes 500km for oil to "burn in" so 3k changes would be almost over kill. depends on your driving style though!

Anyways i think check the bottle and standards and work out how "semi syth" is magnatec % wise and then compare it turbo light(i would be interest in the results).

I'm sticking to turbolight personally(wait when the 20% store wide sales are on and pick up 3-4 bottle and u pay like 45 bucks for 5L :) ).

Please don't put Castrol oil in, especially not magnashite (I know 2 people whove had their engines destroyed by Castrol oil).. I would only use German Castrol or if I were desperate the EDGE line.. If I were you I would just pay afew more bucks and get a better cheap brand like pennzoil or penrite

I was told by a mechanic who does alot of work on skylines not to use it.

He took apart a seized quad cam mustang engine and he said it turned into a thick sludge at the top of an engine, blocked it up or something.

He recommended semi or fully synthetic 10 - 40W for a GTS-T with about 100k on the clock.

Stick to Motul Turbolight.

Only do a change every 3000k's if you take it hard / spirited runs / track days, or if your really anal or if you can get free engine oil... LOL!

If non of that then do a change at 5000k's.

Change your oil filter too when doing an oil change.

I do mine every 5,000kms, genuine nissan oil filter and 5w30 Repsol Competition Full synthetic , if i am going to take it to a track day or anything like that i am going to use 10w60 Alfa Romeo Racing oil.

where do poeple buy the motul oils from? autobarn? and whats the rough price for 5 litres?

so far ive been using penrite semi synthetic, 5-40, and im happy with it. also i use repco oil filters all the time too.

From memory, Auto barn and Supercheap Autos sell them.

    • 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!
