Anyone know where you can still buy Valvoline 80/90 GL-4 gear oil.I can only find GL-5 and have been told it has sulpher in it which is hard on the brass syncros
My buddy put this in his 66 Chevelle. It say's it's for yellow metals.

I got the Valvoline at a local place called Knechts. I'm sure they don't have them where your at, but I've seen it at almost all the parts places. O' Reilly's, Schucks.
i will have too make a trip across the border and see what I can find. Thanks
I was able too find the oil at a GM dealership. What is the best in a 12 bolt posi rearend
I put GM lube and posi additive from the Chevy dealer in my new rebuilt rear end. That's what Motive Gear recommended.
The same oil as tranny 80/90 gear oil from GM
NO it's strictly rear end lube and be sure to get the additive if it's positive traction.
Sounds good I have the additive already just wondering what was the best rear end oil too use. thanks
I know you already found your trans oil, but you can also still get CRC Sta-Lube 85W90 GL-4 at NAPA.
For the rear end, you can use a 80W90 GL-5 oil & the GM posi additive.
Thanks for that Jeff. Love the Ash Gold car
^^Thanks - right back atcha. Rallye Green looks great on a 68.
