Review on 🚗 Vacuum Car Smoke Machine Leak Detector with Built-in Pump 12V: Ideal Automotive Diagnostic Tester for Fuel Leakage, Pipe Leaks & Intake System Performance by Andy Baker

This fog machine is amazing. The smoke is thick and the vacuum lines are easy to find with this machine. The trick is not to add a lot of mineral oil or there will be no smoke. There were no instructions, but the Amazon listing suggested adding 50-100ml of mineral oil. However, my smoke machine was not complete. One of the positive terminals was missing an insulated wire. Update in 3 days. The seller contacted me and offered to send me replacement cords for my smoke machine. Because of this type of customer service, I have changed my original rating from 3 stars to 5 stars.
