Molyslip Gearbox Protection


Recommended Posts

Is it any good? Is it worth a dose into the gearbox?

Gearbox changes gears sweetly and vehicle is quite quiet and that is the problem I can hear the gearbox whooshing and weeshing (doing it's thing) will the stuff quiet it up so that when a fault develops I'll hear the noise and not keep wondering it that woosh is something to worry about.

Vehicle is a 300tdi 110 CSW with an R380 Gearbox. :D

LT77/R380 gearboxes have an internal oil pump, I personally wouldn't add any other fluids to the ATF or MTF :D

When did you last change the gearbox fluid ?,

if not recently, it maybe a good move, use the later MTF fluid LR recommend :D

Haven't bought any yet but noticed it in halfrauds a while back and it got me thinking.

Says it's also good for diffs as well

Gearbox oil was probably changed by the garage I bought it from approx 30,000 miles ago Will probably change it soon weather, job, and life permitting....... :D

There was a thing in the press last year (and I think it was reported on LRE forum) about Slik50 being unable to uphold any of their claims about reduced friction, noise, fuel consumption etc.

Although Molyslip is different, I would be inclined to think that they are all much of a muchness.

If it was really that good - I imagine all the motor oil manufacturers would include it and the car manufacturers insist upon it!

Personally, I'd turn up your radio a bit and save the money.

Has anyone actually seen Moly Slip?

It's heavy, grey and gooey and in my opinion would just lie like lead in the bottom of your LT 77 gearbox.........

I have used it in north american vehicle diffs and the results were not noticable..........

A lot of that stuff is pure "snakeoil" although i swear by STP oil thickener :)

I think it all boils down to what you want to believe................... :)
