Bell & Gossett Oil Tube L25201 Lubricant for Pumps and Motors, 2.5 Ounce

Extends the life of the heating system!

I wish I could get this product in a larger container.

Used other oils and the pump stayed noisy all year. This oil immediately quieted it down.

Met expectations and worked great

Best oil on the planet

This is the lubricant my HVAC guy recommends, and since its kept some older pumps running smoothly for a few years now, who am I to argue with success?

Works great for boiler circulating pump

Very good oil! great stuff will buy again!
