We strongly advise against it, and so do OEMs. ‘Baby oil’ is not designed as a smoke vapor solution especially for EVAP testing. No automaker in the world approves using baby oil vapor in their vehicles. In fact, the largest baby oil manufacturer clearly states: “It [baby oil] is NOT intended to be used nor should it be used in or in conjunction with any mechanical or automotive component or equipment.” Our smoke solution is a pure, refined mineral oil-based blended chemistry that doesn’t breakdown and produce a foul odor like baby-oil.
The simple answer: any company suggesting you use baby oil in a smoke machine is likely not licensed to use our OEM-approved/mandated UltraTrace™ or UltraTraceUV®.
