WARNING!
This is just cheap generic "silicone oil" thermal compound.
Silly kids on websites try to declare a winning thermal compound based on 1-2C temp difference but that's not what matters if you have an even remotely quality (flat) heatsink and compound at least thin enough that the heatsink settles in.
What is more important is the base oil, as synthetic ester base (as used in Arctic Alumina, Silver, etc) is an extremely desirable formulation for modern high-heat CPUs.
If you have a CPU with a metal thermal spreader on top, you might be able to get away with using this stuff but don't even think about using it on a faster-grade flipchip without a heat spreader (like some video cards, northbrides or Athlon XP).
Considering how many years (uses) the typical person can get out of a dozen or so grams of Arctic Silver (or your preferred synthetic stock grease) it's hardly worth a couple dollars savings to get this stuff, and it can damage CPUs if used long-term because silicone oil is inferior and pumps out more than the specifically engineered synthetic stock types. You're left with islands of solids and the temp of the part may not even accurately indicate temp of other portions of the chip.
In other words, your compound dries out too much, but a certain % of core is still contacting nardening grease. If that area of the processor happens to be above the thermal diode, your temps will not accurately reflect the entire core as it would (come closer to) if entire surface was uniform as it was when first applied.
