Quick note, since I just got off the phone with support, because I couldn’t tell which pump I had, and therefore which oil to buy.

In the high-pressure pump oil change instructions, it notes that there are different types of oil for each pump type:

> **[Pump Box Oil Change — WAZER Support | The First Desktop Waterjet.](https://support.wazer.com/resources/maintenance/procedures/pump-box-oil-change)**
>
> The Pump Box oil needs to be changed after the first 50 hours of use, and then every 300 hours after that.

It may be difficult to users to tell the difference and determine which pump they have.

**GP Pump**

- Has no holes in the main pulley wheel
- Has no WAZER branding
- Is older model sourced from General Pump
- Takes 15oz (440ml) of included Pump oil, or a Non-Detergent SAE 30 or ISO 100 oil
- OEM oil is General Pump AW Series 100

**KLV Pump**

- Has holes in the main pulley wheel
- Has large WAZER branding cast into the main body
- Is new model designed by WAZER (Casting markings seem to indicate this might be a Botuo pump)
- Takes 10oz (300ml) of included KLV pump oil, or 15W-40 engine oil
- Oem oil is Francool APCD15W-40 Engine Oil

Hope this is helps anyone looking for information on changing their high-pressure pump oil.
