### ⭐⭐⭐⭐⭐ Specified Fluid
*by M***W on 20 September 2019*

This fluid is the only fluid specified by Welch. For a few dollars, why take a chance with your pump, your research, or other expensive testing by using another fluid?

### ⭐⭐⭐⭐⭐ Oil from the same company that made the pump!
*by R***K on 26 May 2018*

A necessary item to use when you have a very expensive, excellent, long-lasting vacuum pump. Stick with the same manufacturer as the pump, and don't quibble if the cost is a little higher.

### ⭐⭐⭐ Makes me feel like the company is not looking out for the customer ...
*by R***T on 26 October 2015*

I bought this for a Welch DuoSeal 1400 vacuum pump. I don't know what is so special about the welch oil, and I am certain there is a generic replacement oil that could be purchased from a petroleum product manufacturer for a lot cheaper. No issue with the product, but the proprietary "blend" expense drops it to 3 stars. Makes me feel like the company is not looking out for the customer who purchased an expensive tool. This oil can get contaminated by residual droplets/vapors from the airflow of the suction side, and must be changed periodically. This means a continual expense for the customer, and a cash cow for the MFG. Again, product itself is great.
