The Autool PT620 is a digital oil pressure tester for the engine, with a measuring range of 0 to 29.4 bar and an accuracy of 0.5% of full scale. You connect it in place of the oil pressure sensor and see the actual oil pressure, rather than just the on or off state of the oil pressure warning light.
With 18 adapter types in metric, UNF, NPT and ZG threads, it fits the oil pressure port of most engines in cars, motorcycles and trucks. The 2.8-inch screen shows the current pressure, the highest and lowest values, the difference and the measuring time. It is supplied with an oil-resistant transfer hose, a right-angle quick coupling and a case.
ADVANTAGES
POINTS TO NOTE
Applications and functions
The PT620 is intended for workshops that need to establish whether an oil pressure fault lies in the engine or in the sensor and wiring.
Measurement functions
- Actual pressure: The oil pressure at this moment.
- Pmax and Pmin: Hold the highest and lowest value.
- ΔP and measuring time: Difference and duration of the measurement.
Where to use it
- Oil pressure warning light on or flashing: Distinguish low pressure from a faulty sensor.
- Ticking on cold start: Whether the pressure builds up quickly enough.
- High mileage: Indication of oil pump condition and bearing clearances.
How to use it
- Removing the sensor: Unscrew the oil pressure sensor and catch the oil.
- Fitting the adapter: Screw in the appropriate adapter and connect the hose.
- Zero point and unit: Zero the tester and select bar, kg/cm² or psi.
- Measuring: Start the engine and read the pressure at idle and at higher engine speed.
- Comparing: Compare the reading with the manufacturer's specification.
Special functions and features
What makes the PT620 practical:
- Three pressure units: Bar, kg/cm² or psi.
- Zeroing and hold: Zero before measuring and hold the value.
- Backlight: 2.8-inch screen, also readable in the engine bay.
- Automatic shut-off: After 5 minutes with no operation and no pressure.

General
- The manufacturer of the tester.Brand
- Autool
- What the tester measures: the pressure in a system or the quality of a fluid. This tells you if it suits the job.Type of tester
- Oil pressure tester
Measurement
- The lowest and highest pressure the tester can measure. The range should match the system being tested.Measuring range
- 0 to 29.4 bar (426.6 psi / 30 kg/cm²)
- How much the reading can deviate at most, as a share of full scale. The smaller, the more reliable the result.Accuracy
- 0.5 %
- The smallest step the display shows. A finer resolution reveals small pressure differences.Resolution
- 0.01 bar
- The pressure the sensor can withstand without damage. A higher limit gives more margin during a pressure spike.Overload limit
- 40 bar
- How many types of adapters are included. More adapters mean the tester fits more engines and systems.Number of adapters
- 18 adapters
Functions
- The tester records the highest and lowest pressure and the difference between them. Useful for spotting fluctuations.Highest and lowest reading
- Yes
- The display shows how long the measurement has been running. This tells you if the pressure remains stable long enough.Measuring time on display
- Yes
Display and power
- The size of the display, measured diagonally. A larger display is easier to read.Screen diagonal
- 2.8 inches
- The display is illuminated, so you can read it even in a dark engine bay.Backlight
- Yes
- Which batteries power the tester. Standard batteries are widely available.Power supply
- 4 AAA batteries of 1.5 V
- After how many minutes without use the tester switches off automatically. This saves the batteries.Automatic switch-off
- After 5 minutes
- The ambient temperature at which the tester functions correctly.Operating temperature
- −10 to 60 °C
