Gday i'm just about to change my Gearbox oil... thinking of going with Redline lightweight Shockproof. Just got car imported and dunno if stock oil is in it still, so thought I'd change it anyway. (car has done 75,000km)

Just few questions....

Should i go easy for first 1000km after change?

Most people use this if they have gearbox crunching i have read so is it ok to use it if u dont have gear crunchin etc? Im guessing its ok?

Also is Redline way to go? I dont have noises so maybe something cheaper or i am i best off going all out?

P.S. Did try a search guys... sorry if it has been covered!

Thanks

make sure you use the Super Lightweight Shockproof (its a 75w90)

the lightweight shockproof (75w140) is too heavy and makes it hard to put into gears when warmed up

and i dont believe the oil needs to be run in but it cant hurt behaving for 100-200 K's

EDIT: Redline is a very good way to go top stuff! but me personally would go Royal Purple MaxGear

and yes i would go all out the better the oil... the less wear... the longer and healthier the gearbox lives

yes Royal Purple i would say is a better product than Redline

i have also heard that thing about Redline with newer gearboxs

i would say that Royal Purple is as good as Redline in the smoothness of the gearbox BUT Royal Purple has this thing they called "Synerlec" which claims to Polish the metal as it lubricates and i have a test thing they done with it and it did exactly that didnt wear at all but polished the metal (can post it up if you want)

it also has a friction additive in it called "Synslide"

Sorry for the blatent plug but just stating why its my opinion that Royal Purple is better

Hope it helps

Apparently Redline Lightweight Shockproof isnt designed for synchro gearboxes as it doesnt allow your synchros to mesh properly. Also it supposedly has a short lifespan as it is designed for racing applications. I had it in my gearbox but recently drained it out and put in Redline MT90 (which is designed for synchro 'boxes). The shifting is a bit notchier with the MT90 however. If your not getting any crunching from your gearbox I wouldnt use any of the shockproof oils.

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
