FAQs

What kind of engines can I use this tester on?

This compression tester is designed for use with all petrol engines.

How do I interpret the compression readings?

Compare the readings to the manufacturer's specifications. Low readings may indicate engine problems.

What should I do if the gauge reads zero?

Make sure the adapter is properly connected. Check the engine's ability to crank over and if it does then look for any leaks or major mechanical issues.

Can I use this tester on a diesel engine?

No, this compression tester is specifically designed for petrol engines and is not compatible with diesel engines.

How do I clean the compression tester?

Wipe the gauge with a clean, dry cloth. Avoid using solvents or other chemicals.

What does the psi and bar scales represent?

They measure the pressure in the cylinder during compression, with psi being pounds per square inch and bar being metric units of pressure.

Where can I find the compression specifications for my engine?

You can usually find engine specifications in the vehicle's repair manual or online resources specific to your vehicle.

Troubleshooting

Gauge doesn't register any pressure.

Ensure the adapter is securely connected and the engine is cranking. Check for leaks in the connection.

Readings are consistently low across all cylinders.

Check valve timing, or potentially a worn valve, or piston rings.

Readings vary greatly between cylinders.

Inspect for issues such as head gasket failure or valve problems in the cylinders with low compression.
