i haven't actually gone under my car and looked to see if my car has VLSD...but from what i've read everywhere all canadian 240's have the VLSD....
well during our winter months here my car would get stuck every 50 feet cuz of all the dam snow..but i've noticed that when i do get stuck one wheel will spin and the other will be planted..even if i just lightly touch the gas or floor it....is there something wrong with my diff or should i maybe confirm if all canadian 240's have the VLSD...i just changed the diff fuild a few months ago...

touchdown. i don't think that is quite correct...
the additive are for clutch-pack LSD...
the Vlsd coupling is a sealed unit w/ some silicone fluid or something like it. I think it works when the operatin temp is reached.
But, what do I know... I too have an 89 SE w/ an open differential. Hopefully, some members w/ Vlsd's can confirm this.

I might be wrong... I remembered someone talking about LSD one time and they said something about an additive. Of course, he has a 70 Chevelle... probably not VLSD. Sorry for the confusion.
To check if you have LSD, the easiest way is to do a burnout and have someone else watch from the back, and they'll tell you if both wheels are spinning. It's a fun test

Bright orange sticker on the drivers side of the differential. YOU CAN'T MISS IT. Use the search button. I know that info is in there. Not all Canadian cars have the LSD, it's a myth. If you only spin one tire, it's an open diff. I put the addative in mine and it works just fine. I certainly don't think it will hurt.

Any LSD additives will not do squat. If you get premium gear oil, do it for it's lubrication properties. Don't waste your money on something that's tailored for LSD. The Viscous coupling is sealed so the LSD additive will not touch any of the LSD parts.
As far as the orange sticker, not all diff's have it. It could fall, off, some may not come with them at all, but mine did not.
Using the wheelspin test is not always accurate. In certain circumstances, even a VLSD may spin only one wheel.
Best way to check is to the lift the rear wheels off the ground. Put the car in a gear(motor off). Then try spinning the rear wheel. Open diffs will have little resistance. only the weight of the wheels will be felt. A VLSD will have much more resistance and will not freely roll very much after you stop spinning it.

The VLSD will spin only one wheel in the event that the silicone in the oil has not expanded (thus causing the grip). It will act like an open diff otherwise. Thus spinning one wheel will not always tell the true story. A picture, however, is worth a thousand words.

I just got a VLSD, its sitting in the garage...I can tell you right now that even though its not at operating temperature, I can BARELY turn the output shafts different directions, we are talking it takes more than 100lbs. of force to do it. Also, if you jack the whole back of the car up then both wheels should spin the same way, if they spin opposite directions, you have an open diff.
