i been using royal purple for the last 7 months and its great you gotta give it time to work though they recommend changing it every 10000k

i work at autobarn in gympie and we sell it for 80 bucks for 5litres its good shit the bees knees in oil (my opinion anyways) :blink:

Yeah but isn't usually recommended to change oil in turbo cars every 5000 K's??? :)

Ok just a couple of things. The Royal Purple that you get for under $100 is a Group IV oil, so compare that to the Motul 8100 which is also Group IV.

If you want to compare the 300V then you can only compare that to the Royal Purple racing oil which is around the same price as 300V, im pretty sure it is a Group V oil, but not 100% sure on that one, will have to speak to the Royal Purple rep next time i see him.

Problem with Royal Purple is that it started getting a great name for it self when Street Commodores did a test on all the oils in the country and Royal Purple won it be a mile stone, all the other brands including Motul performed horribly. Suddenly they got the attention of all the oil companies and they went "Hang on a sec, wtf is going on here!", so they investigated it and a law suit became of it. The problem was Street Commodores used a machine that didn't simulate engine loads on bearings (i believe it was a gearbox load simulator from memory) and that's why all the oils performed so badly. They published a big apology but not many people saw that one, they just remembered Royal Purple dominating it, hence their great reputation began in Aus :)

Nice history lesson for ya.

Nothing wrong with Royal Purple, i sell heaps of it and it's a great oil. If i couldn't buy 300V at my work i would go the Royal Purple 10W40 because Motul don't make a 10W40 in a Group IV oil.

Well before this I was using the 300V and apparently its the same rating as the royal purple, they both have an SL rating is that the rating that you talikng about. because apparently the way oil is rated is by these letters eg. LG, LJ, LS, LM and apparently LM being the best. Please if some1 knows wat I'm talking bout than tell me if it's right or wrong. Caus this is coming from a performance shop owner not me.

The normal Royal Purple is a group IV oil, not a group V. The Royal Purple XPR Racing oil might be a group V but im not sure. Group V oils are those which use synthetic esters (diesters, polyolesters, alklylated napthlenes, polyglycols etc.) Such as Motul 300V which was the first oil in the world to use double esters.

The ratings on the oil simply say "they meet these ratings or exceed them". These ratings were derived to seperate group I, II, II and IV oils; with IV being the highest. Once esters were created for use in 100% synthetic oils by Motul in 1971 and then again using double esters in 2004 in the form of 300V, they could no longer class them in a group IV because they were above it, therefore group V oils were created.

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
