    • Solary Automotive Smoke Machine Leak Tester Review: Reliable, But Requires Extra Purchase
The Solary Automotive Smoke Machine Leak Tester is a solid tool for diagnosing EVAP system leaks, vacuum leaks, intake leaks, and more. It produces a steady smoke output to help identify leaks quickly and accurately. However, one thing to note is that it does not come with smoke fluid, meaning you’ll need to buy a solution separately before using it. Performance & Features ✔️ Efficient Smoke Output – Produces consistent smoke for easy leak detection ✔️ Versatile Use – Works on EVAP, turbo, intake, exhaust, and vacuum systems ✔️ Durable Build – Compact and well-constructed for shop or home use ✔️ Easy Operation – Simple hook-up to a 12V battery and ready to go Smoke Solution Requirement Since the machine doesn’t include a smoke solution, you’ll need to purchase mineral oil or baby oil separately. This is a minor inconvenience, but it would be more convenient if a small starter bottle was included. Final Thoughts The Solary Smoke Machine is a great tool for professionals and DIY mechanics. It delivers accurate and reliable results, but keep in mind that you’ll need to get smoke fluid before use. Despite this, it’s an excellent value for diagnosing leaks efficiently. Rating: ⭐⭐⭐⭐☆ (4.5/5) Pros: Strong smoke output, easy to use, versatile applications Cons: No included smoke solution, requires separate purchase ... show more

    • Great for the price!
Needed one to check for leaks and didn't want to spend a lot of money. This one is cheap and with a $10 bottle of fluid it works great! Plenty of pressure and smoke. Feels a little cheap but seems tough. Nice and small with a big fluid reservoir. And the instructions are somewhat helpful.

    • Excellent tool, worked great!
This smoke machine leak detector is a total game-changer for diagnosing vacuum and EVAP leaks. I’ve used it several times now in my garage, and it’s worked flawlessly every time. The smoke output is steady and visible, making it easy to spot even the smallest leaks quickly. Setup was simple—just add oil, plug it in, and you're good to go. It’s saved me a ton of time and guesswork on troubleshooting. For the price, this tool easily pays for itself after a couple uses. Highly recommend for any DIY mechanic or professional shop looking for a reliable diagnostic tool! ... show more

    • This is pretty vehicle for the tailpipe yeah you could buy an adapter that goes anyways
OK, I have a different style of this machine, but I got it cause I had some extra money and I figured what the heck I’ll just buy it because I can and I couldn’t find my other one so instead of spending two days looking for it I just bought it in the next day. I got it. It does not come with the fluid the oil you need to make it make smoke, but I needed to help find a an emissions problem that I have with. I think it’s either a cracked exhaust manifold or a leak in the exhaust pipe system somewhere, but it should work good cause I’ve used one in the past to find a vacuum hose leaks just note that sometimes you have to use a different type of a light to see the smoke either a halogen or a regular bowl the old-fashioned flashlight to sometimes smoke is not visible or not easily seen in the certain lights. It works well. ... show more

    • Works great
It worked very well. My BMW would stall randomly when coming to a stop. After some googling, I found out the problem was most likely an air leak in the boost system. With this machine, I found a leak from my charge pipe to the intercooler. The gasket was damaged so I ordered a new gasket and replaced it myself. This thing saved me hundreds of dollars. I would give it 5 stars if it came with oil and was ready to use. The pictures make it seem like the included bottle is filled with oil. ... show more

    • Good machine
Good product, found leak quickly. Used baby oil, smells bad obviously but gets the job done. Doesn't come with any oil but just borrow some from uncle Diddy and you'll be good.
