Oil Change & Lubrication Guide for Your Quincy QT-10 Compressor

Oil Change & Lubrication Guide for Your Quincy QT-10 Compressor

Your Quincy QT-10 two-stage reciprocating compressor is a serious workhorse. Keeping up with oil changes is the simplest way to protect that investment. Clean, correct oil reduces wear, improves cooling, and keeps your pump running strong for years.

Recommended Oil: Quin-Cip-D

For the QT-10, always use Quin-Cip-D, a high-quality SAE 30 (ISO 100) oil specifically formulated for heavy-duty reciprocating compressors. This oil offers excellent thermal stability and film strength to handle tough shop conditions.

When to Change the Oil

Quincy recommends changing oil:

• After the first 100 hours (break-in period)
• Then every 500 hours or at least once per year. Whichever comes first.

If you operate in hot or dusty environments, consider shorter intervals for added protection.

Step-by-Step Oil Change Process

1. Shut Down and Depressurize

Turn off power to the compressor, unplug it, and drain any tank pressure using the receiver drain valve to ensure safety.

2. Drain Old Oil

Locate the oil drain plug on the pump crankcase. Place a drain pan underneath, remove the plug, and let all old oil drain out fully. Reinstall the plug securely when done.

3. Refill with Quin-Cip-D

Remove the fill plug or breather cap. Slowly pour in Quin-Cip-D (SAE 30, ISO 100). Check the sight glass or dipstick carefully — for QT-10, the capacity is approximately 2.5 quarts. Fill to the correct level without overfilling.

4. Reinstall and Clean Up

Secure the fill plug, wipe up any spills, and dispose of old oil properly according to local regulations.

Protect Your QT-10 for the Long Haul

Skipping oil changes is one of the fastest ways to shorten your compressor’s life. Using the right oil and sticking to a regular schedule ensures your QT-10 delivers reliable air for years to come.
