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

They do the job, but seem very expensive for the small quantity of oil you get. I was able to find a quart of 20 weight non detergent oil which comes out to be a fraction of the cost per ounce.

Excellent oil good price and fast shipping

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

This pump and motor lubricant is a game-changer! It effectively reduces friction and extends the lifespan of my pumps and motors. The high-quality formula provides smooth operation and prevents wear, ensuring optimal performance and efficiency. A must-have for anyone in need of reliable lubrication, this product is a true lifesaver for maintaining the longevity of pumps and motors.

great price for oil for pump

I have an old hydronic boiler (for radiators) that had not been oiled for quite some time. This worked perfectly to keep the pump running smoothly. I only wish that it came in a larger bottle because I used most of it up in a single application.

Ive used this oil on the circulating pump for our boiler and it works great. I also use it on my bench grinder and miter and table saws with the same results.
