Hey guys

I want to replace my engine oil in my R34 (RB25DET Neo). I've done some research on the best oils. Everyone has their own opinion on oils but the majority seems to be leaning towards the Motul Turbolight 4100 engine oil. So I went to a couple of stores to check if any has them in stock but na-da, nothing. Autobarn has 2 Motul oils which are 6100 synergie and 8100 x-cess. I asked one of the clerks at the store and he said that I should try Auto Pro, so I rang two Auto Pro stores and they both told me that Motul has stopped producing turbolights and that Motul has replaced it with Motul H-Tech 100 Plus. Is this true?

Has anyone tried Motul H-Tech 100+? Is it really the replacement of turbolight and is it the same or better?

Also, a store here in Perth has Motul 300V Chrono in stock which apparently is some high quality shit for if you're going to the races or something but it's $110 for 4L! And I only use my R34 as a streetcar and daily drives. I'm not planning on racing with it or going sideways. Will the 300V be worth it as a streetcar?

Also, now that winter is starting should I look at buying a lower viscosity oil?

What do you guys reckon?

300v is awesome, made my car noticeably faster. No joke. Not wallet friendly though.

I used to use 4100 religiously and it's a good oil but yes, you can get equal/better oils for same price and it pissed me off that it was so hard to find, so ended up switching oils to something most stores stock.

Oh ok, I thought turbolight was good for your turbo or something lolz, I don't know much about engine oils. But I'll try get something full synthetic 10w-40 like junkie said

Nulon Hi-Tech 10W-40 or Penrite HPR10 will be fine. Grab a few when they are on special at Supercheap. I have 4x bottles of HPR10 in the carhole

Cheers mate :) I'll do that tomorrow.

Anyone els want to voice their suggestions, I'm still open for anything els to try

for me, Castrol edge seemed to hold temp and oil pressure better, I noticed oil temp went up when I switched to the penrite 10-tenths. Will likely go back to the Castrol at next oil change, but would use penrite again if needed, and it is widely available.

I bought new oil, filter and sump + washer bolt (from nissan dealership). Came home, jacked the car up, went to go unbolt the sump and f**k me, the bloody thing is stripped...

Now I've got a problem that I can't be bothered posting a new thread about so I'm gonna post here. It keeps turning anti-clock wise but it won't come out, not even a little bit. $@!$$@!!! Previous owner or mechanic must have over tightened it when they changed the oil. I really don't want to buy a new drain pan. This is so stupid! :rant: I tried getting a screw driver under the sump to lever it into a thread but cant get a gap between the sump and pan. Also tried loosening and at the same time pulling it with pliers but no dice.

GUYS, don't overtighten stuff!!

I would assume the same as the coolant drain bolt: 34-44 Nm?

I just tighten it and when it starts getting tight, just nip it a little. Won't fall out lol. You can put thread sealant on the sump so it never leaks.

    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
    • OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!
    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
