AutoLine Pro Automotive Smoke Machine Fluid Solution is designed for reliable use in a wide range of automotive diagnostic applications. This 4.4oz packet delivers consistent, dense smoke output that helps visually trace potential leaks across systems such as EVAP, vacuum, intake, exhaust, turbo, superchargers, EGR, and engine cooling. Formulated from high-quality USP-grade mineral oil, the fluid produces clean-burning, low-odor smoke with minimal residue—suitable for use in environments that require careful handling around sensors and delicate components. Compatible with most automotive smoke machines on the market, this fluid works seamlessly with AutoLine Pro testers and other major brands. For those using the latest VENTUS Li-Ion powered smoke machine, a specific VENTUS fluid is recommended. Packaged for ease of use and storage, this solution is ideal for both professional shops and home garages. As part of a U.S.-based, family-run business, AutoLine Pro focuses on providing dependable diagnostic tools that help users maintain and inspect vehicle systems with efficiency.
