Is anyone out there using Motul synthetic gearbox and diff oil? What products are you using specifically and what has been your experience. I am looking at (for the gearbox) Gear 300 75W90, or Motylgear 75W90. What grade oil does the diff use? I am assuming 75/90 too.

I am very happy with the 300V for the engine and thought I would give Motul a go at my gearbox and diff. I DO NOT want to hear about Redline.

I have searched and only found vague information re: motul gear oils.

thanks

I have Motul gear300 oil in the gearbox. before it i had castrol in there, and i must say the difference was amazing. Alot of the notchiness went, and the gears feel alot smoother. But i'm goin to go for a better gearbox oil on my next change

Hey there mate, I have an S15 which is about to go in for a FULL service(diff, gearbox,brakes, plugs, radiator etc). I went for Motul 8100 XS 5w-40 full synthetic for the engine, Motul Gear300 75-90 for the gearbox and Motul GEARBOX 80-90 mineral for the diff. DO NOT use Motul FF-LSD if you have the stock LSD!!!! I know this sounds very strange but the S15 manual says to use NON-LSD oil for the gearbox and diff(which GEAR300 and GEARBOX are NON-LSD). I think FF-LSD is to be used with lockers and mechanical diffs. Bear in mind you could use GEAR300 for the diff also, i opted not to because the manual states the S15 diff needs 80w90, not sure if i could get away with using full synthetic Gear300... would love to try it for the diff sometime.

Thanks for the replies guys. I'll reply to this thread after a few hundred kays with the oil change.

Not happy with it.  The cheap s  hit stuff that was in there that was thicker was better.  Or felt better.  Once its warm its ok, but by geebus it takes forever to warm up.

Dave, I had the same problem with the Redline oil, you really had to give the car some stick before the gearbox felt any good or else it was very 'notchy'.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
