Did I read that right: Valvoline conventional gear oil does not have a limited slip additive in it?

So I bought valvoline conventional gear lube after reading about temps in conventional vs synthetic. Just figured valvoline would have the additive in it. If I read correctly, it does not.
Would it be better to repurchase one with the additive or just go buy some??

I don’t need the additive in the front right as it is a standard open Dana 30?

if it matters, I have a 04 lj with the dana 44 in the rear

thank you guys for your help
 
What you figured matters none, if it is not in it, it is not in it.
If you need your limited slip with clutches to work as intended, either buy one with addictive or add addictive.
What is the last time you replaced those clutches? They might be worn out to the point of it not matter whether you put any addictive in there or not.
 
I don't know of any mainstream GL-5 gear lubes like Valvoline that don't have the friction modifier additive. Look on the rear label where it very likely says 'Compatible with limited slip differentials' which indicates the additive is present. In the very remote chance it doesn't go to your local auto parts store and pick up a little bottle of the additive and pour it into the rear axle.

It is very hard to find a GL-5 gear lube suit for our axles on store shelves that don't contain the additive. The additive is compatible with all axles with or without sn LSD so it's easier just include it since few know if it's needed or not.
 
It actually says - “limited slip differentials top off only (consult owner’s manual)

it is Valvoline high performance 80w-90.
Based on that just go buy a small bottle of the additive and pour it into your rear axle. There is no need to change the gear lube.

Buy something like this, the additive is easily found in the lubricant section of nearly any auto parts store. https://www.amazon.com/dp/B01EKNPQPQ/?tag=wranglerorg-20

What you buy doesn't need to say Mopar on it, any friction modifier additive for a limited slip differential will be fine.
 
Contrary to what most gear oil bottles say if you have a clutch type LSD you need to put additive in there. I would also make sure that additive is OE (Mopar, Ford, AC Delco, Dana) and avoid things like Equa-torque and TransX.
 
Redline makes a GL-5 with no additives, but most have it. If you're sure the oil you got doesn't have it just buy the additive separately and mix it in.
 
On many factory LS differentials, you should add the factory LS additive regardless of an additive in the base oil. For example, Ford often recommends the Motorcraft additive even if there is generic additive in the base fluid already.
 
Valvoline is what I have been using for a long time now.
They do have the LS on it.
Most Valvoline gear lubes do, I was shocked to learn yesterday that some don't. It was surprising to figure out the OP's particular Valvoline gear lube does not have it.

Update

The world is spinning toward Synthetic Everything (synthetic oil, synthetic gear lube, synthetic meat, synthetic social life). Conventional motor oils are getting difficult to find. Conventional gear lubes are still around, but apparently fewer include the friction modifiers for LSDs.

The four current Product Information sheets on the Valvoline website under Gear Oil:
https://www.valvoline.com/en/flexfill-full-synthetic-gear-oil/
https://www.valvoline.com/en/high-performance-gear-oil/
75W-90 FULL SYNTHETIC, "has limited slip additive"
75W-140 FULL SYNTHETIC, "has limited slip additive"
80W-90 apparently conventional, "does not have limited slip additive"
85W-140 apparently conventional, "does not have limited slip additive"

So if you're talking Valvoline, and you like conventional lube, I no longer see any products which come with the friction modifiers.

I ordered Mopar Limited Slip Additive (Friction Modifier) on Amazon, using Jerry's link above, but received a Ford Motorcraft bottle. Non-returnable, non-refundable. Sometimes Amazon is your friend, but not today. Maybe it would work fine, but I ordered it because it said Mopar all over the webpage. I found Dana Spicer Differential Friction Modifier Additive - 43161 at 4WheelParts right up the street, for slightly less money. That's probably what's in the Mopar bottle anyway.

Mopar, Ford and Spicer are all the same juice with a different sticker.

ARB states not to use an additive as it reduces the life of its seals.
