Slick 50 - Moly Engine Protector

Post by Glaf » Wed Aug 14, 2019 2:38 pm

Does anyone use this brand of Molybdenum Disulphide engine oil additive?

If so any comments?

I wouldn’t put any of this stuff in an engine. Modern lub oils are chemical masterpieces, and specified to coexist with the materials used for bearings and cylinder walls. Mixing this gunk in is unlikely to end well, despite the advertising. If you’ve got an old worn out engine you’ve got nothing to lose except your cash, but in a high speed, high temperature, high BMEP engine you are playing with fire.

It’s actually a pity we throw away the lub at this magic “annual” oil change, as there is no science behind it. Does anyone check the primary characteristics like viscosity, lubricity, pH etc? No. Does it get recycled? No. In a world of shrinking resources, this high cost, high tech item deserves more respect. Improved filtration alone could probably double the change interval, and adding in some simple treatment of the used oil could probably see it reused several times. But think of all those garage visits that wouldn’t happen, and those high margin oil changes... do I hear the crackle of vested interests? Anyway electric cars don’t need it so change is a coming.

My previous BMW M3 was only every 2 years. I don't think my F Types engine is any more highly tuned or stressed.
I agree it should easily go 2 years unless you are doing high mileage.
Just a money maker for the dealer.

I digress though, and Slick 50 wouldn't go near any of my engines.

I did use it in my my Morris minor, along with a product called piston seal. All bollocks. In the wonderful world of synthetics leave well alone. Just go out & thrash the pussy cat. Very reliable engines. The V6 does have the odd injection problems but generally they are very reliable & do not require anything but the standard oil change.

In the US they seem to have mitigated against this with annual applications of BG44K.
