Hello, VEVOR support team!

I am currently using your KQ-1K (TW-1K?) vacuum pump and I would like to confirm the correct type and viscosity of oil recommended for optimal performance and longevity. I understand that using the wrong oil could affect the vacuum level, cause increased wear, or lead to maintenance issues, so I would greatly appreciate your guidance. Could you please clarify the following:

• The recommended oil type (e.g., mineral, synthetic, vacuum-grade, etc.)

• The ISO viscosity grade (e.g., VG 32, VG 68, VG 100)

• Whether there are any approved brands or specifications

I should follow I wasn’t able to find this information in the instruction manual, and I have some doubts regarding the recommended #100 oil (found somewhere in the comments on the vevor web-page). Thank you in advance for your assistance. I look forward to your reply so I can ensure proper maintenance of the pump.

Best regards, Siarhei.

Dear Customer,

Thank you for your patience. We sincerely apologize for any inconvenience caused. We take your feedback very seriously and are committed to assisting you in resolving this issue. Regarding the issue you inquired about, after verification, we have determined that the 100-grade oil you saw in the review is not the best choice. We recommend using 46-grade vacuum pump oil for this pump, as it is the most suitable option. You can purchase and use it with confidence. If you have any further questions, please feel free to contact us at any time.

Sincerely, Customer Support
