Need Help on Fluid choice

[67_Slimer]

I have an 833 in my Dart. Well built 340 and aggressive driver I've been running the Sta-Lube 85W90 hypoid gear oil in mine. When I just went to purchase more , it looks like it has been discontinued.
1) Am I wrong that it's been discontinued?
2) If so , what is a good equivalent oil to run in there or the proper fluid ? Was that even a good fluid to run in it?
Thank you in advance.

I just use 85W90 in mine. That's just me. Why Hypoid? Thought that was for Posi in rear diff.

I had a guy that specialized in 833s and for some reason he recommended that. I'm not sure why. Looks like it's not really that big of a deal. Thank you.

Kind of a can of worms question, because there’s so many varied opinions.
I have to agree with the Lucas if you want a good quality product.

For what it’s worth, when I ran older manual transmissions I would customize the fluid mix depending on how the trans reacted.
Some work great with 85/90 and some worked better with 30wt, and then some even better with ATF.
It depended on how it shifted mostly.

Thank you , makes sense. Car is street driven but power shifting happens from time to time.

I too experimented years ago with 80-90 and Redline Synthetic. I really didn't notice much. I don't drive my ride much in the winter so I'm good.

POSI? Thats a 4 letter Chevy term. Anyway, I remember having ATF in my 74 360 Duster 833, & I'm pretty sure it came from the factory that way.

Yes, some did I've heard.

Not sure the old gears and bearings were tight enough for ATF, but it would certainly shift a lot easier in colder weather and it will be a lot noisier.

I looked @ brewers' site and they recommend Brewers recommends
GL4SL ONE GALLON STA-LUBE 85W-90 WEIGHT GEAR OIL
Get a gallon jug and you have all you need. You can get it at Napa and Walmart.
