Review: cheap and works as well as the much hyped stuff. - Good to have more than the 10 milliliter syringe of stuff that dries to a powder, quits working after a year, then glues your cpu to cooler so you destroy the cpu trying to service the cooler. time will tell if this works better. Compared to the silver based stuff this replaced, no loss in cooling efficiency with any of my 3 desktop computers.
Review: Super Lube works great! - This is a great product and a great value! I used this to repair a coffee machine, and placed this thermally conductive paste between the heating element and the hot plate. It has been working really well so far and it's been about 6 months.

## Questions & Answers

**Q: What is the thermal conductivity?  (W/m/K)  "High thermal conductivity" means nothing.**
A: Super Lube Tech Sheet says "Thermal Conductivity: 0.55 watts/meter K"  http://www.super-lube.com/files/pdfs/Technical_Bulletin_Heat_Sink_Compound.pdf

**Q: Can I use this grease on my engine block heater cartridge?**
A: If you have a dry heater block hole (element does not touch antifreeze inside the block), this is the grease to use. Worked great on my Toyota Camry.

**Q: What is the heat tolerance?**
A: Says on back of tube the temperature range is -40 to 500 degrees Fahrenheit

**Q: Is this ok to use on restaurant equipment? I need to apply some on the heat element of a popcorn maker. It won't touch the food but wanted to be sure**
A: I used it on the temperature probe on the inside of the machine. You should be good with your popcorn machine.
