LSD Diff fluid without additive?

I have a 2001 Wrangler Sport with rear D44 and LSD.

I bought Valvoline High Performance Gear Oil 80w-90. It says "All hypoid differentials (conventional and limited slip)".

Does this mean you don't need an additive or it just supports LSD (requiring an additive added)?
The guy at the parts store said it "supports it" and still needs an additive.

Also, is 80w-90 the correct weight?

Thanks guys!

Unless it specifically says it has the LS additive, you'll need to add it.

The majority of rear end lubes are compatible with regular and LS gears/bearings, but LS normally needs an additive for the clutch pack.

What that means is that it already contains the friction modifier additive required by your Tracloc limited slip differential. Very few GL-5 gear lubes don't already contain the additive. Don't add more, it can screw up the Tracloc's operation if you add too much. SOMEtimes you need just a tad more than comes in the gear lube but that's not very often.

The reason most gear lubes already contain the additive is that the additive is compatible with all differentials whether they have a limited slip or not. You would have to look hard for a high-end gear lube that does not already contain the additive.

I emailed Valvoline's customer support and they replied:

"All of our branded automotive Valvoline Gear Oils (High Performance, DuraBlend & SynPower) contain approximately 3% of the limited slip additives. If your vehicle requires more additives, we suggest that you add the extra needed for maximum performance. Valvoline HD Gear Oils do not contain any limited slip additives."

This would be nice to have on the label. Sometimes I really wonder who creates product literature. It makes me want to go with another company just because of this, but I find inconsistency with so many I would be severely limiting myself.

That information is on the back label. If the back label says it is compatible with limited slip differentials, the additive is there. If it doesn't say that, it doesn't have it.

Yes it is. But my issue was the word "supports". Supports, as in supports a diff with LSD and supports the use of an additive. Or supports, as in all you need for an LSD.

I have ran into several instances in the computer industry where it goes either way and sometimes ended up with a product that doesn't do what I thought it would.

The guy at the auto store created all this confusion in my head. Though I'm glad he brought it up, because the wording isn't as clear as I would like.

All I'm saying is the wording isn't as definitive as I would like. It can be, and has been, interpreted 2 different ways.

You're over thinking this, don't get into analysis paralysis. If the label says it is compatible with a limited slip differential, it is. The word "support" is not in the picture or on the label.

I understand your confusion on the label wording. But in the end it is not all that critical. LSD additive is used to make the clutches slip not grip. So even if no additive were used the LSD would grip more not less. I like my LSD's to grip as much as possible so I do not use any additive with them, and I use the old "style" gear lube that does not contain any additive from the mfg. If your LSD grips too much then just add a little at a time drive it for say a week and see how it is. If it still grips too aggressive then repeat the process.

Ya your right, it doesn't say "support". It's that guy's, at the auto parts store, voice in my head. I hope he's real.

Anyway thanks. I know what to put in it now.

Yesterday, I bought the manual transmission lubricant and LSD additive from the dealer. The transmission lubricant is pretty expensive, but I still have almost four months of warranty left. Since I already have the additive, which gear oil should I use. I was told I need 2.5 pints for the front differential and 4.0 pints for the rear of 80w-90 gear oil. Thanks for any information.

I'm a little confused, what is the manual transmission lubricant for? I hope not for the axles. If it is for the transmission, what transmission lube did you buy and exactly which manual transmission do you have? Or if you're not sure, what model year wrangler do you have and which engine do you have.

It's called Mopar Manual Transmission lubricant for an 04 Wrangler Sport a 5 speed transmission. I have a six cylinder 4.0L. I bought the additive for the Trac Loc Dana 44, but I still need to buy the gear oil for the front and rear differentials. Thanks for the help.

But there is not much point in buying the additive before buying the oil as the oil may have it already.

Too late now! Is there any gear oil that doesn't have the additive? Thanks
