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

Best oil on the planet

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

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.

Needed a second tube for maintenance, used the whole tube the pump came with on installation

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!!!!!

A few drops in my B&G 100 series keeps it running nice and smooth.

Good

Excellent oil good price and fast shipping

While expensive, it was needed and should last a while. No issues of any sort and arrived quickly. I tried to find a place that had it cheaper, and even my local place was charging more.

This oil works great for my pump which was on its last breath , The pump is on an outdoor wood fire boiler (heatmor) I had already purchased a pump for replacement so I would have one on site . But after putting this oil in the hole on the end of the pump it went silent , runs like a new one now .
