Key Features
Live, Min/Max and Differential Oil Pressure
Digital Pressure Measurement
Measures engine oil pressure with a digital measurement system across the displayed range up to 0–426.6 PSI, with 0.01 display resolution.
2.8-Inch Backlit Display
The 2.8-inch backlit screen shows pressure information clearly, making readings easier in dim workshop or engine bay conditions.
Multi-Unit Switching
Switch pressure units between PSI, Bar, and kg/cm² to match different service habits and vehicle information references.
Max / Min / Differential Display
The interface can show current pressure, current maximum pressure, current minimum pressure, differential pressure, and measurement time.
Data Lock, Clear And Zeroing
Use the lock key to hold the current interface, clear test data when needed, and zero the pressure value before testing.
Riveted Copper Adapter Set
The included copper adapters help support common engine oil pressure sensor port connections and resist wear and oxidation during normal use.
AAA Battery Power
PT620 uses four 1.5V AAA batteries. Open the battery cover on the back of the device, insert the batteries with correct polarity, and close the cover securely before use.
Oil Pressure Connections
Threaded adapters, a right-angle quick connector and an oil-resistant hose support connection to engine oil pressure test points.
18 Adapter Types
The PT620 comparison and adapter images list 18 accessory connector types for engine oil pressure testing setup.
Common Thread Sizes
Shown adapter sizes include M10×1.0, M10×1.25, M12×1.25, M12×1.5, M12×1.75, M14×1.25, M14×1.5, M16×1.25, M16×1.5, M18×1.5, 3/8-24UNF, 1/2-20UNF, NPT-1/4-18, NPT-1/8-27, NPT-3/8-18, ZG1/8-28, ZG1/4-19, and ZG3/8-19. Match the thread and sealing method to the engine test point before connection.
Right-Angle Quick Connector
The right-angle connector helps in tight engine bay spaces where a straight connection may be inconvenient.
Oil-Resistant Hose
The transfer hose is designed for oil pressure testing connection needs. Check hose and fittings before every test.
Auto Power-Off
The device automatically powers off after 5 minutes of inactivity when no pressure is applied.
Pressure Accuracy
Accuracy: 0.5% FS.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safe Use
Control Hot Oil, Hose and Pressure Exposure
Do Not Overload
Use the gauge within the rated testing range and do not exceed the listed overload pressure.
Match the Adapter to the Port
Select the suitable adapter for the vehicle and engine oil-pressure sensor port. Do not force an adapter into an incompatible port.
Secure the Connection Before Starting
Connect the measuring probe to the engine oil-pressure test point securely. Start the engine only after the fitting is properly connected and the gauge is ready.
Release Pressure Before Shutdown
After measurement, shut down the device under atmospheric pressure.
Inspect the Hose and Fittings
Check the hose and fittings before every test. Tighten any loose fitting before operation.
Check Fittings First
Regularly check parts that need to be tightened or connected. Tighten loose fittings before operation.
Avoid Corrosive Liquids
Avoid contact with corrosive liquids and clean parts that contact chemical media after use when needed.
Protect The Housing
Do not rub the product against rough surfaces or damage the housing during storage and operation.
Store Dry
Store the product in a dry place. Do not store it in hot, humid, or poorly ventilated locations.
Compare Oil Pressure with Specification
Use the oil-rated hose and correct engine adapter, then compare pressure at the specified temperature and engine speed with the vehicle specification.

Buyer Questions
Pressure Connection and Reading Questions
What Does AUTOOL PT620 Test?
PT620 tests engine oil circulation pressure in compatible cars, motorcycles, trucks, and other vehicles after matching the sensor-port adapter and rated pressure. It is not a cylinder, fuel, GDI, transmission, or brake pressure tester.
What Pressure Range Does PT620 Support?
The product images show a display range of 0-426.6 PSI, 0-30 kg/cm², and 0-29.4 Bar. The user manual lists the range as 0-30 Bar and the overload pressure as 40 Bar.
Which Pressure Units Can PT620 Display?
PT620 supports PSI, Bar, and kg/cm². Use the pressure unit button to switch units according to your testing requirement.
Does PT620 Save Multiple Sets Of Test Data?
PT620 supports data lock, interface lock, data clearing, and pressure zeroing. Do not treat PT620 as a multi-set data storage model unless confirmed by the latest product version and seller support.
What Batteries Does PT620 Use?
PT620 uses four 1.5V AAA batteries. Open the battery cover on the back of the device, insert the batteries with correct polarity, and close the cover securely before use.
How Many Adapter Types Are Included?
The comparison and adapter images list 18 accessory connector types for PT620. The adapter image shows metric, UNF, NPT, and ZG thread options, plus a right-angle quick connector and oil-resistant transfer hose. Confirm the required adapter size before testing.
Do I Need To Zero The Gauge Before Testing?
Yes. Power on the gauge and zero the pressure value before testing. The manual also notes that shutdown should be performed under atmospheric pressure after measurement is completed.
Can PT620 Be Used For Fuel, GDI, Transmission, Or Brake Pressure Testing?
PT620 is for engine oil pressure testing. For fuel pressure, compare PT630 or PT635. For GDI pressure, compare PT640. For transmission oil pressure, compare PT650. For brake system internal fluid pressure, compare PT660.
