Has anyone used this product before or can recommend something else.
My gearbox on a 306 xtdt '94, having covered 100k is a little 'stiff', especially when cold. I intend to change the transmission oil and at the same time use an additive.
Any advice appreciated.
Regards Craig

Change the gear oil by all means..But using an additive?.Use at your own risk..I dont like them...Others may say different??

like steve says dont do it new oil to spec is ok but dont add anything . i am a great believer in the manafacturers if it was meant to be there it would be from new and gearboxes are expensive if it messes something up. ...cheers...keo

In all honesty it is simply is down to opinion and personal preference. Slick 50-engine oil treatment is definitely not good for modern cars as it can block up small oil ways and is commonly referred to as snake oil.
Gearboxes do have much greater tolerances so I feel it is less prone to do any damage when compared to engine additive treatments. Perhaps if a very small amount was added to the gearbox then it may even do some good if the vehicle is used at high excessive revs and in very tough conditions. It really is down to personal preference but remember it is not in the manufacturers interest to make gearboxes that last forever that is why they would never recommend any additive products.

I had difficulty changing gear in my Rover 100 (metro). As a last resort before taking it to a garage I squirted in a tube of Molyslip (about £7 from Halfords).
Within about 24 hours (40 miles) the gearbox was as good as new.

I would seriously caution against the use of any of these "magic additives" as they can cause premature problems due to their formulations. I have a copy of an AA report that says that Slick 50 does absolutely nothing other than empty your wallet!
I asked a chemist recently who had tested many of these products and this was the reply I recieved - scary stuff!
General Remarks on Chlorinated Additives.
A number of ?add-on? additives intended to improve the performance of commercially available automotive lubricants have been marketed in recent years, under such names as ?Xxtralube ZX-1?, ?Metol FX-1?, ?PPL Anti-Friction? and ?Activ-8?.All such products share the following characteristics with ?X-1R Friction Eliminator?:-
1)They all contain chlorinated paraffin ?exteme pressure?(EP) compounds first used in the 1930s in heavily-loaded industrial gearboxes, and in some automotive transmission applications, mainly hypoid gears.
2)They all corrode copper-based alloys at moderate temperatures, easily exceeded in all engine, and most transmission applications.This problem was recognised in the 1930s, and chlorinated compounds were never used in transmissions with bronze bearings or gears. No responsible manufacturer ever suggested using them in engines where their increasing activity at high temperatures could lead to piston ring corrosion and bore glazing. (For the same reason, modern ?hypoid? additives are not used in engines, even though they are much safer than any chlorinated additive.)
3)X-1R Friction Eliminator and its clones are based upon very outdated technology, which was abandoned by responsible lubricant manufacturers for automotive transmission uses in the 1950s. Chlorinated compounds still find applications in metal working, but their use is on the decline because of health and safety considerations.
4)When burnt, chlorinated paraffins produce corrosive hydrochloric acid, and organo-chlorine compounds including the highly poisonous phosgene gas. Apart from these corrosion and health hazards, with petrol engines the deactivation of exhaust catalysts is also a problem.
5)Unfortunately, these additives give spectacular results in simple EP test machines such as the ?Falex?. As a marketing ploy, a demonstration of this type looks impressive to those not aquainted with the above facts. Also attractive is the low cost of chlorinated compounds, allowing profits of several thousand percent to be made.
Spend money on a decent oil is my advice.

i too have used molyslip in a gear box,,and it worked a treat
really really good
but the above article is written by someone who really knows thier stuff....really interesting reading :)
also gearbox's dont suffer from the same heat problems as the engine,,so if u changed the oil every couple of yrs,,then that would be very good for the gearbox..
me,,i chabge mine every 2 yrs :)

That's quite interesting from oilman. Many thanks for all of the replies.
I think my box could definately benefit from the oil change and i'll see if it makes any difference.
