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'd suggest searching for a seller of Repsol oils, especially the full synthetic. I've found over the last 4 years this to be the very best oil I have used.(currently have 500hp 351 cleveland and 1UZFE equipped Landcruiser using it)

I used to be a Penrite fan, but have changed my tune. If you ever get the chance, look at 50 bottles of oil from Penrite, note the differing colour of the oil inside, then look at 50 bottle of Repsol, same colour, always. REason for change from Penrite was the number of manufacturers that specify Repsol as standard oil. Mercedes trucks, Volvo, Audi. Also the high detergent factor and how clean the oil comes out looking even after 5000klms. The synthetic Repsol isnt cheap, about $55 for five litres but doesnt break down and go the horrible black colour. I noticed that when you you sniffed the Penrite it had a very strong burnt smell to it.

Next step on all 3 cars will be an oil analysis from the Castrol labs to look at metal contents etc etc.

Yes i agree with you on that!!

Turbolite not being a full synthetic.....Bad news!! , it just means your paying an extra $20.00 per four litres just for the name, its crazy!

The only oils we should be paying the $ for are full synthetics!

Anyone using Royal purple oils??

I've found Motul to be generally underpriced for what it is when compaerd to more famous brands. It seems to be the biggest brand oil where you're not paying for the name. Turbolite may not be the best oil for a car with a turbo because it's a semi-synth, but I've used it in my bike (11k redline) and found it to be better than other brand full synthetics. I would agree that a full synthetic would be better with a turbo due to higher running temps, but I have never used a bad or even average Motul oil. You can do far worse than turbolite, even if you stick to 100% synthetics. I use 8100 on my car and have not found anything better for the price.

I'm thinking of using Motul Turbolight Semi Syn. in my fully rebuilt RB25Det with forged pistons/GTR rods etc.. Will this be suitable? I'm not concerned about price, just want to find & use one of the best possible oils to run it in. What oils have you guys used to run motors in with good results?

I found that Pennzoil Synthetic had a wider viscousity range that I thought would be suitable for my car as it has quite a few km on it. Quick flow at cold startup & a bit thicker when hot for an older motor.

SAE 5W-50 for about $55. No complaint as yet, but I haven't compared it to the more expensive, harder to get oils. I've been using it for about a year.

Motul 8100 X-Cess is a better choice because it's 100% synthetic. Not the best, but good for the price. If money is no object then maybe consider the 300V oils, which are the next "rank" up.

do not use synthetic or even semi synth to run in your motor, or the rings wont bed in and it will use a huge amount of oil

use mineral oil to start with and change frequently, then move up to semi synth and after a few thousand kms use fully synthetic.

load up the engine but not for long periods and dont use high revs, dont drive it softly or the rings wont bed in.

Royal Purple, Lucas, Fuschs, and Red Line Synthetic oils, all of which are an esther based full synthetics all of which you can get a 10-40w in ideal for rb's. These are all oils myself and my old man have experience with and in my opinion nothing comes close, for a high end oil.

I believe they are the best oils on the market except Repsol could be in there but i cant get that anywhere to give it a trial.

I went with Motul 5w40.

It definitely holds better oil pressure when hot in peak hour traffic.

I found the std mineral crap to be dropping oil pressure in that circumstance.

Valvoline is fairly good, head over to bobistheoilguy.com and read the oil & filter reports.

I'm using a Purulator Premium oil filter as it flows really well and filters really well. In the tests it is on par if not ever so slightly better than the K&N Oil filter which is 4x the price.

Purulator PureOne oil filters are one of the very best in filtration however they do restrict flow somewhat.

I used the Pureone filters for run in (when there's a bit of crap running around the oil from bed in) and now on to the premiums that flow better.

I'm happy with the Motul 8100 5w40. Doesn't drop oil pressure when idling in peak hour traffic on a hot day with the a/c on.

I've had Mobil 1 (not in this motor though) which did appear to thin out and drop oil pressure when idling, hot day, a/c on. :rofl:

      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.

      Strange issue RB25DET wont start

      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.
