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...

New Skyline owner here, stock 1990 GTS-t Just did an oil and filter change, it needed it badly, was starting to make lifter noise and the old oil was quite black. Went into Repco to check what they had, and came out with 5L of their own brand (blended by Penrite) semi synthetic 10-40W, a filter and a bottle of Nulon engine oil flush, all for pricely sum of $49. Put half the Nulon in at the car park and drove it 4km gently home, then put the remainder in and idled for 10 mins. Drained for 30 mins screwed in the new filter and refiled with the Repco oil.

No more lifter noise, idle is smooth as and free revving, engine only has 60 000 on it and still seem nice and tight, oil pressure at idle is just above 2 and just under 4 when revved, oil consumption is next to zero.

Any opinions on Repco Semi Synth 10-40? Since this motor is quite fresh should I be looking some 5-30 for my next change, or should I stick to the 10-40 since I live Qld.

Cheers

Mike.

Can you post some specs on it? I honestly wouldn't trust something like that, they probably have developed it to undercut their other products and make a decent margin on it. Semi synth sounds av.

I would go for one of the full synths mentioned in this thread for $59, you don't need the engine flush crap.

Couldn't find a spec sheet at the Repco site, so the only information available is what is written on the package...

if its one thing ive learnt from owning a skyline, you cant go buy cheap shit like that, its generic repco stuff, you aint driving a commondor or ford anymore, these cars are performance!! I used to own a commondor and the oil was like $20 but now owning a skyline I get the good stuff $65 5litre bottle of 4100 MOTUL, you cant run cheap semi synth in ya RB, thats just a heads up, even if you do, you will probably have to change it more often

I mean even the cheapest oil out there is going to be fine for daily driving, it is only when you are out tracking it or giving it a good run through the hills that you want to better oils that don't break down and burn. However when the price difference is so tiny, you might as well get a known really good oil like Motul 8100 but don't spend more than that, eg the chrono oil etc which is over $120, that isn't value for money.

Leave it in there until next change, but next time go something a bit more quality.

The car is my new daily drive and it has an auto transmission so it's likely to never see a race track, a nice brisk run up mountain road is another story. At $36 including a free oil filter and being produced by Penrite convinced me to give it a try, if I can find the $60 full synthetic without having to travel too fare out of my way then I'll give it a go next change.

Go to your local autobarn, get the gulf western synx-3000

Probably one of the best semi synths out there and i rate it better than the nulon full synth

Will be on my 3rd change shortly

lol, motul's 4100 range IS semi-syn (that's what the "technosynthesse" on the bottle means)

not that there's anything wrong with semi syn, you need a mineral content to run ethanol based fuels like e85 and i ran my old 25 on 4100 turbolight for 3 years @ 300rwkw before it popped

what about all those RB30 powered commodores and R31's that are still going perfectly fine after 1 million k's running on Coles brand oil

it isnt a Bloody F1 motor

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
