AUTOOL Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles

This is great! Easy to use! I used a small amount of mineral oil. It makes a very good amount of smoke, it's adjustable, I turned the dial about half way. 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. If you're in an apartment or don't have 110 AC, this is great because it runs off 12 volts DC. If you needed you could connect it to a power bank but the car battery works well . I was using it for approximately 10 minutes and it did not drain my car's battery to a point where it would not start. There was plenty of cranking power after I thought. I'm not sure how many amps it pulls . As far as the Air supply, It does not have a built-in one. You need external Air supply but you do not need to have shop air compressor, I used a bicycle pump with some acrylic tubing, a tire valve stem, hose adapters and a quick coupler for an air compressor hose for the female end to connect to the smoke machine. The bicycle pump method worked perfectly. I could control the flow of of air by hand. Very easy and there is no risk of pumping in too much air during your testing. You do not want to have a high amount of air pumping into that machine and filling up your engine Chambers with the too much air could blow something. Only need about 5 psi. No worries with there the bicycle pump method and it was very cheap to rig up. This is a must have diagnostic tool for all mechanics. This has helped me find vacuum leaks with ease. I would have never found this leak I had, it was a massive leak of air my car has in the throttle body area. It's in a tight spot. This helped me to determine where the exact leak was coming from. The TB gasket turned out to be fine after 35 years, it was the gasket to the air tube that seals around the mouth, which was an easy fix. I also had a small leak around and after market CAI intake elbow joint. I confirmed the repairs with the smoke test and the car ran much better. I recommend this.

Works great, lots of smoke. Beware the heated mineral/baby oil will stink up your garage for a long time. So bad I am unable to use this inside my garage. In storage the smell is still so bad, I have to store this outside. For the money I am satisfied. Still could not find the Evap leak on my 2005 Suburban, but not the fault of the machine. Think the leak may be on the top of the gas tank where I cannot see the evap lines. The pressure gage is a must. It is missing on other similar priced smoke machines. Tells you there is a leak if the ball does not fall to the bottom. To test, close off the smoke tube and it will go to the bottom.

Great piece of kit. Paid for itself within 15 minutes of arriving on my doorstep (overnight - thanks Amazon!). Immediately helped me identify the cause of a mysterious air/fuel issue I’ve been fighting for weeks. Easy, cheap fix, but in a spot I never would have been able to get eyes on without a stream of smoke and an inspection mirror. Saved a lot of time and money swapping out engine sensors trying to identify the true cause of the issue. I chose this unit over other similar and dissimilar models particularly for the built in air regulator and the assortment of fittings. While cheaper units with the built-in mini air compressor are appealing, the compressors have a high failure rate and a very low airflow volume. This kit is as reliable as the compressor I connect it to. Plenty of smoke output, and the adjustable smoke output is helpful, as too much can actually obscure the source leak. Only slight complaint is I feel the manufacturer should have included a single use 20ml container of smoking fluid (mineral oil). I knew it didn't include any, and I already have butcher block mineral oil on hand, but the principle remains. Overall, an affordable, full featured and compact unit.

Works really well. Unit uses fluid like baby oil to produce smoke. I've used it a few times already. Both to find leaks on the intake side and also the exhaust side. For the exhaust side, I really like the inflatable airbag you pressurize. Stick it in the tail pipe, pump it up until it inflates to the size of the tailpipe and there is no more air gapes between them, then pump the exhaust full of smoke to find your exhaust leak. Does what it's supposed to do. Don't know if it would last in a shop where it would get used constantly but great cost effective alternative for DIY's.

I used this to find a vacuum leak in my vehicle. After reading some of the lower star reviews, I was skeptical, but purchased it anyways. Some one star reviews indicated user error in my opinion, so I took the chance. It started making smoke in short order and worked better than expected. I made sure not to add too much liquid... probably 9ml as opposed to 10 since some reviews said they added 20. Directions say 10. In this case, less is more. Anyway, it blew a ton of "smoke" out and once hooked up, revealed a tear in an intake boot that I couldn't visually see. The only thing I didn't like is that you need an air compressor. I had one, so no worries, but it would be nice if it had something self contained to produce pressure. Maybe it stops working on subsequent uses as some have reported, but for my needs, it worked great. Instructions were obviously written without a good Chinese to English interpreter but it wasn't too hard to figure out. I'd recommend it.

Working great. I'm a retired auto tech and do minimal repairs since retirement and this has already helped me find pertinent vacuum leaks on 4 vehicles. Very good price for the quality, Very satisfied!👍

This unit kicks ass. It helped me find a leak and paid for itself the first day. So easy to use and uses very little smoke additive. The additive has to be purchased separately.
