GL-5 = BAD; Finding GL-4 gear oils can be a pain

Re: Finding GL-4 gear oils can be a pain

Yeah, JRP is ok. But a new race parts outfitter just opened up down the street, and magnus motorsports is down the street too, and my euro tuner guy has all the crazy additives and stuff always in stock and redline as well. he usually orders a case of redline for a rainy day… because I usually come in during the spring or the fall. haha

thnx though!

my friend called me today to tell me the radiator fans i bought were available at jrp, but they would be 80 bux a pop there. i got them for 80 shipped to my house- no duty.

Parts are expensive in Canada because everyone gets them from keystone network. Which is already expensive as it is.

I thought it was no longer within my reach, but magnus is cool with me now, and the euro guy moved to a location even closer to my house. hahah. his place was closed and i was sad for a bit.

PM guys… thread partially jacked already.

F*CK! i thought i read the thread right the first time.... but i guess not cause i just put gl5 in this morning..... FML… i need gl4 right? just for further further clarification

the advance auto here in Macon sells it for about 9 bucks a quart. not that any of you guys r gonna drive down here to humidity hell for some gear oil

Napa has it.

On KY last rebuilt granny, the idiot didn't know what to put in. He went to the store and bought gear oil. Obviously it was gl5. Did a drain after maybe 4k (didn't think of the fluid) and it came up glittery and sparkly.

Put new fluid in it but it was to late. Hard to get into first…bearing noises....ended up junking the 71c and replaced it with a t5....much better

If anyone is stuck and can't find redline gl4....its everywhere here…I can ship it.

as well as gl-5=bad, gl-4=good, what will be your opinion about transmission oils for 30a (GL4 is recommend):
Motul Gear 300 75W-90 (API GL4 and GL 5/MIL-L-2105C) - but this one is GL4 AND GL5
and this, which is GL4 firm, but
Motul Gear MB 80W
API GL-4
specified for heavy duty truck transmissions: Mercedes Benz, MAN or ZF (Ecolite, Ecomid, Ecosplit, Astronic 1&2 etc) but only for transmissions w/out hypoed gear.

I would stay away from anyhting that is marked GL-4 and GL-5. As said earlier, it is more like a GL-5 with a secondary GL-4 rating and will most certainly harm your synchros. Strictly GL-4.

I use 50% blend of this oil with Redline in my 92SE Maxima with VLSD 5SPD. Still smooth in below zero weather.

My buddy over here has a dealer who is opening up a shop soon.
He can get whatever oils and fluids I need, sweetness..

He got my friend Royal Purple street performance yadadada.
100$ For a 12Q box.
Friggin sweet.

I talked to him about getting me some Amsoil for my transmission/diff
Haven't talked about pricing just yet, but it'll be sweet to have a case of RP, just synthetic, nothing spectacular

You can easilly sign up and be a amsoil rep to recieve the discount.

Redline MT-90 has been great in my 71C. Haven't had to deal with the summer heat yet though so we will see how it holds up then.

I used that with mtf 50/50 and it was awsome. All until I blew up that transmission.

Im probably never going to use mt90 again since I got my t5. Mike, if you want my extra mt90 bottle let me know. Its collecting dust.

BG Synchroshift II is a GL4 fluid that I have good luck with before. Haven't tried any in my z yet, however it works great in my Sentra Spec V's 6spd tranny.

Have anyone of you tried pennzoil 80w-90?
