I use Motul 300V and unlike apparently most of you I change it after 20,000km (including track days). I have sent samples for oil analysis and the results have suggested there is no reason to change it more often.

Kiwi, over what time frame is the 20k done. oil companies used to tell us oil loses its viscosity after 6 months, now with synthetic they say 12. Wondering if your analysis proves it can keep for longer.

I like that you dont throw away expensive oil that's in good condition. There should be more of this good sense.

See the attached. The Oil may be in "good condition" but its only good for the intended application which is track days. The data sheet on Motuls website states 300v is intended for track-GT-Rally (short distance race) use. This in my opinion would mean it provides worse protection than conventional fully synthetic oils (i.e. castrol, penrite or even motul 8100) on road use. Thats just my theory anyway based on the technical data sheet.

track days = 300v --> Fully synthetic
Road use = Everything else --> 300v

Since it's not mentioned, I just like to add that 15W50 is one of the most popular oil viscosity choice among GT-R owners around the world. I even remember in GTROC U.K, there was a poll back then, 15W50 came on top, followed by 10W60. GT-R's RB26 is high revving so they like these kinds of "thick" oil. Nismo in fact, has these oils recommended for the RB26. Nismo competition oil 15W50 and Nismo RB26 oil 10W60. The 10W60 is more of the street / track performance one, while the 15W50 is more like the 300V, a race oil.

Also an Evo (CT9A) driver here, and I can tell, these boys has different taste when it come to their oil. :10_wink:

Here's the Nismo 10W60 RB26 oil BTW.

Its like a competition to see who can spend the most on engine oil.  If it is synthetic it will be more than good enough.  When the RB26 came out (Back in the olden days - 1989) Nissan only ever recommended a semi synthetic oil.  The worst synthetic you can buy now is going to be much better than that.

But yeah spend up on pretty coloured boxes and marketing.  Or just buy what's on special.

As an aside Penrite promises to have loads on zinc in it which is no bad thing.

Yup, it’s different strokes for different folks, people will believe what they wanna. But I must disagree it’s just about those pretty packages. Remember, those old Porsches, Ferraris, etc. are also not into pure synthetics back in the day. But nowadays, that’s what they recommend for their old models too. Oil technology have gone very far now, anything that gives optimum performance, and will prolonging engine life will be the one recommended. 

I agree with mick, "ya pay for quality". Because at the end of the day, better quality = more cost. As the saying goes, and this is a car enthusiast favorite, you get what you paid for. ?

I ran Mobil 1 full syn 10W-40 or whatever in my old RB20DET, engine became noisier after about 3,000km of daily driving. Dumped it and put Penrite HPR10, was quiet ever since, and saved myself $20 a bottle. Engine is still going in another car I believe.

So yeah, marketing.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
