The 6-pack of Mastercool vacuum pump oil is a great deal. I appreciate the high viscosity, but I found the bottles to be a bit messy when pouring. A spout would be a nice addition. Still, it works well for my HVAC tasks!

Not the best experience
I had high hopes for the Mastercool 90010 oil, but after using it for a month, I noticed my vacuum pump wasn’t performing as well. Not sure if it’s the oil or my pump, but it didn't meet my expectations. Just okay.

Solid oil, decent packaging
This vacuum pump oil is solid for HVAC applications. I like the 10 oz bottles, but one of them arrived slightly dented. Luckily, the oil itself was fine. It performs well enough for deep vacuums. Happy with my purchase!
