This is the gear oil that GM recommends for the rear axle. The famous "grape juice"
Not sure if this makes it any better than any other synthetic? But so far no oil company lists that they conform to the GM spec.
Found this on another forum:
“Heavy Duty SAE 75-90 extreme pressure GL-5 axle lubricant, new grape sent”
code:
<HR>
<BLOCKQUOTE>Contains:
Hydrogenated trimer and tetramer of decene CAS #68649-12-7
Propene, 2-methyl-, polymers- CAS #9003-27-4
Mineral oil, Petroleum distillates, solvent refined (severe) - CAS #64741-97-5
Amines, C12-14-tert-alkyl, reaction products with 0.0-di-C1- Cas #71888-91-0</PRE>

Explaination of Ingredients:
Hydrogenated trimer and tetramer of decene CAS #68649-12-7
[This is a mixture of PAO base oils]
Propene, 2-methyl-, polymers- CAS #9003-27-4
[This is VII and Friction Modifier]
Mineral oil, Petroleum distillates, solvent refined (severe) - CAS #64741-97-5
[Heavy mineral oil or brightstock to thicken oil]
Amines, C12-14-tert-alkyl, reaction products with 0.0-di-C1- Cas #71888-91-0
[Surfactant, Antioxidant and friction modifiers].
They do not state the EP additives since this info is proprietary.
