The best speed cube can never be called the best speed cube without proper lubrication. Speed cube lubrication is very important and really make a speed cube move smoother with less effort then if it was not lubricated.
There are several lubricants that are suited for speed cubes. These lubricants are silicone based lubricants because speed cubes are made out of plastic. Oil based lubricants are made for metal application and if used on plastic will melt or dissolve the plastic, so stay away from oil based lubricants, such WD-40 and Vaseline (petroleum jelly).
Here are a list of suitable silicone lubricants for your speed cube.

Go for Silicon Oil type lubricants
I would recommend to go for silicone oil type lubricants for several reasons. First reason is that silicone spray type lubricants are very thin and fluid, which means they would dry up faster which means you would have to lubricate your speed cube more often. Second is that silicone oil type lubricants are so much more better then the old silicone spray lubricants. Since it is “oily” it is thicker and would take a long time to dry up so an application of lubrication would last very long. Another reason it is better is that it give the speed cube a much more smoother turning without sacrificing speed. Silicone oil type lubricants are what most speed cubers use today.
When Lubix arrived on the market it did very well, since speed cubers were mainly using silicone spray type lubricants. It gave speed cubes a much more smoother feel while still making movement very fast. It was made specifically for speed cube lubrication and comes in a syringe style applicator which makes lubrication very easy and fast.
This Lubricant is made for RC car differential gears but is amazing with speed cubes. It comes in 50k which is the measurement of density or thickness. Like Lubix it gives speed cubes a smoother feel while making movements very fast.
Which is better?
Neither of the two are better then the other, these two are essentially the same and are equally amazing in making a speed cube perform well. The determinant you should consider when deciding between the two is the price. You can see on the chart that Lubix is $21.99 and Traxxas is $7.99, there is an $14 difference. $14 is already a huge difference but the difference is actually bigger, Traxxas is $7.99 for 50CC while Lubix is $21.99 for 2CC, this is crazy! Why should you pay more for the same stuff? Save your money and get the Traxxas 50k Diff Oil.
