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

This is the circulation pump oil recommended by Bell and Gossett and I would not consider any other.

Great to have since I did not know that the circulator needed to be oiled. My bad completely, I have never oiled this pump in 12 years. A testament to this B & G series 100 pump that it was still running! Oil your pump and the technical manual is HS-105-SM-R4.

Good

3 stars only because there is such a lack of instruction. The manufacturers site and certainly the bottle, gives no real clear answer on how much of this to use. I ended up using way more than I needed to before speaking with an HVAC guy. (yes, thats on me, but in the do-it-yourself age we live in they need to get with the times. YOU JUST NEED A COUPLE DROPS!!!!!

Met expectations and worked great

Does what it is meant for. Used it for my older model B&G pump for my heating system.

We use this for our boiler motor and it seems to do juat fine.

Works great for my water pump.

Extends the life of the heating system!

Maintenance.
