⚠️Important Usage Instructions for Car Smoke Leak Detector
Power Supply: The automotive smoke tester must be connected to a 12V battery to operate.
Test oil: Kindly note that, due to logistics restrictions, we are unable to include testing oil in the package. You can easily buy liquid paraffin or baby oil locally for use as the testing fluid.
First-Time Use: Each time you use the smoke tester car, please fill it with 10–15ml of testing oil. Do not exceed this range, as there will be no space left for smoke generation.
Testing Oil Refill Tips: Only refill when the smoke becomes thin. Do not add more than 15ml at a time. Always drain the remaining test oil before adding fresh test oil.
Safety Precautions
- Do not operate the smoke leak detector continuously for more than 8 minutes; allow it to rest between uses.
- The smoke test machine features an intelligent protection system that automatically shuts off if the internal temperature exceeds 75°C. Please wait for it to cool down before restarting.
- The metal round section of the smoke tester car can become hot during operation—avoid direct contact to prevent burns.

FQA
What testing oil should be added into AUTOOL smoke machine for evap leaks?
If you can’t find a professional test oil, you can buy liquid paraffin or baby oil at your local store as test oil.
How much testing oil should be added into the auto smoke test machine?
It’s suggested to add 10-20ml testing oil for the first trial. Please drain some testing oil out if you add too much accidentally. You can reuse the extra next time.
Can smoke leak detectors detect auto A/C system?
The auto A/C system operates at 1.7-3.0Mpa output pressure, while our smoke leak detectors generate only 0.1Mpa. So the smoke leak detector cannot directly test the auto A/C system for leaks. You can use our machine to perform segment-assisted testing for air-conditioning pipelines.
How to use a smoke leak detector to perform a segmental auxiliary test on the air conditioning pipeline?
First, pressurize the air-conditioning pipeline, then spray smoke and observe if the airflow blows it. If there is, it means that the location is a leak point, you can repair later.

This is great! Easy to use! I used a small amount of baby oil. It makes a very good amount of smoke. It connects with clamps to your positive and negative battery cable so it's totally portable to use outside if you're not able to work on your car at home. This has helped me find vacuum leaks with ease.
