Toby Posted December 28, 2009 Share Posted December 28, 2009 since i don't have time or anything to order Redline. What are some good readily available GL4 gear oils i can get from like advanced auto parts? The nissan dealer said their oil supplier isn't giving them anymore GL4 and switching everything over to GL5... But I read somewhere here GL5 doesn't like our transmissions/transfer cases/differentials so much. So im trying to find some since i gotta get the speed sensor gear from nissan now. The guy said he had a partial drum of GL4 so i'm gonna try and get some from that. but if i can't i need a backup plan. it's all for my transfer case btw Link to comment Share on other sites More sharing options...
MY1PATH Posted December 28, 2009 Share Posted December 28, 2009 (edited) In my area, sta-lube and royal purple are the only local purchase brands that make a GL-4 spec lube. you are correct, GL5 may contain chemicals that can degrade bras and bronze syncromesh gears found in our transmissions. It will not harm our differentials or our t-cases. But if your t-case fwd seal is worn it will mix with your tranny. the GL4 specifation has a requirement that sreens for those harmfull elements. I just use redline because sta lube in 75w90 is getting harder to find (local vendor now only carries 75w140) and I can order reline directly for less than I can buy royal purple. In fact I just ordered a gallon over the hollidays and it still arrived in 3 days. Edited December 28, 2009 by MY1PATH Link to comment Share on other sites More sharing options...
Toby Posted December 28, 2009 Author Share Posted December 28, 2009 3 days is still just too long for me. Literally. as soon as I get my speed sensor gear it's going right in and the fluid is going in. There's no more waiting. It's been at my step brother's shop for WAY too long. He's lost his patience because it's been in the way of his business. Link to comment Share on other sites More sharing options...
RedPath88 Posted December 28, 2009 Share Posted December 28, 2009 Have you called all your local parts stores to see when they can get some RedLine in? My local National Auto Parts had it the next morning, would have been the same day, but I asked for it to late in the afternoon. Assuming you simply cannot get RL soon enough... If you have any CarQuest parts stores near you then give them a call, make double sure they understand GL4 ONLY not GL5 "GL4 Compatible". I have not tired others, but a nearby (Spanaway/Parkland WA) CarQuest has.. or "had" a while back.. straight GL4 in a five gallon buckets in stock. Also, call local gear and hydraulic shops, there used to be one down near the Port of Tacoma that always had drums full in stock. Who knows now though Link to comment Share on other sites More sharing options...
Toby Posted December 28, 2009 Author Share Posted December 28, 2009 im from PA... i'll call around today. I called most the ones near my work a few days ago and none of them had it. So i'll have to wait and see Link to comment Share on other sites More sharing options...
adamzan Posted December 28, 2009 Share Posted December 28, 2009 I think you can use gm synchromesh Link to comment Share on other sites More sharing options...
Alkorahil Posted December 28, 2009 Share Posted December 28, 2009 The nissan dealer said their oil supplier isn't giving them anymore GL4 and switching everything over to GL5... But I read Yes, that is correct. The part number for Nissan is: 999MP-1XGPP0P for GL4 of GL5. It is onr of the few things where the formula changed but the part number did not. The only way you will find GL4 is if you can find a dealer with older stock still on the shelf, but you will have to ask them specifically if they have the GL4 bottles. Your best bet would be a rural or older dealership if you really want the older bottle. -Rob Link to comment Share on other sites More sharing options...
yozsi Posted December 28, 2009 Share Posted December 28, 2009 I think you can use gm synchromesh Thats a good alternative to gl4. Link to comment Share on other sites More sharing options...

They said they know they have a partial drum left. So i'll have to see. Link to comment Share on other sites More sharing options...
Terrano1992 Posted December 28, 2009 Share Posted December 28, 2009 Yes, that is correct. The part number for Nissan is: 999MP-1XGPP0P for GL4 of GL5. It is onr of the few things where the formula changed but the part number did not. Maybe, this is one of modern synthetic "universal GL-4/5" fluids? "Mobilube SHC" (Exxon/Mobil), for example? By the way, excellent 75W-90 gear oil... Link to comment Share on other sites More sharing options...

What are some good readily available GL4 gear oils i can get from like advanced auto parts? it's all for my transfer case btw Just a thought but yours is a stick right? Dex 3 is what nissan recamends(if you dont want to get there tranny fluid)for there transfor cases... Yep just looked it up and its says,89 models get API GL4 75w-90 and 90-95 get Dexron ATF...So if your getting some heavy oil in your transfer case I can see a rebuild in your futher...

It previously had gear oil in it. So no. No rebuild. Only putting back what was originally put into the transfer case. There's other people here i recall who've put Gl4 in their transfer cases with no problems. Link to comment Share on other sites More sharing options...

You can use Dexron or 75W-90 GL-4 (75W-90 GL-5 is suitable also) for any transfer case, 87 to 95 year. However, Dexron is recommended for cold regions.

87pathy Posted December 29, 2009 Share Posted December 29, 2009 the transfer case isn't a problem. its the tranny you gotta take care of. you can use the pensoil syncromesh stuff. if your not sure about an oil, call the manufacturer and ask them if its soft metal compatible.

Toby Posted December 29, 2009 Author Share Posted December 29, 2009 (edited) gear came in today. going to ask about whatever GL4 they have left. Pathfinder should hopefully be on the road soon. Edit: No Gl4 at all. My step brother is going to see what he can find. Edited December 30, 2009 by Toby Link to comment Share on other sites More sharing options...
