Review: Very Happy with unit. Small tweaks could make this perfect. - Very happy with this unit. I am a DIY mechanic, so I don't expect this to see a TON of use, but it takes the guess work out of the 'mystery' of fuel injectors. This comes as a 4 injector system. This made the most sense to me over larger units and here's why. If you have a 4cyl engine, no problem, test all at once. If you have a 6 cyl engine, you can test 3 injectors with a plug in the 4th, which lets you test an entire bank at once. yes, you have to do the exercise twice to cover all the injectors, but thats not a huge deal. If you have an 8 cyl engine, same as the 6 except you wont need the plug to test each bank. I had a hard time determining the difference between the CT150 and the CT160 other than aesthetics. Here's what i've determined to be different: 1. The vials on the CT160 are shorter. the CT150 shows 140mL vials, where the CT160 has 100mL vials. This could be an issue when testing aftermarket or performance, or E85 injectors. 100mL fills quickly, but work just fine for testing standard injectors. 2. the fuel rail on the CT150 is secured using 2 threaded rods on either end, while the fuel rail on the CT160 is secured with a single rod in the center. This concerned me a bit at first, as running an odd number of injectors might cause an issue with keeping the fuel rail sealed on all injectors. I can say, 3 injectors does not cause this unit any problems. Running a single injector may ( I have not testing this yet) but this would be easily corrected, either by running a junk injector opposite the single injector being tested, or a simple spacer to keep the fuel rail level. 3. It appears in photos that the CT150 comes with a lid for the ultrasonic tub. My CT160 did not have a lid included. This is problematic, so I will be fashioning a lid to keep shop junk out of the ultrasonic, and to keep the fluid from evaporating. 4. The controls are a bit different, as the CT150 has buttons to control fuel pressure while the CT160 has a knob. Without physically using the CT150, id say the knob feels better and I would call it an upgrade. In addition, control layout is slightly different. 5. I am not sure how the CT150 controls the ultrasonic bath. But I can speak for the CT160. The controls for the CT160 are the two red switches on the front right of the unit. One for ultrasonic, and one for heat. The injector pulsing is controlled independently using the control panel and one of the selections on the menu. This is ideal, as it allows independent use of the ultrasonic cleaner if needed. 6. the CT160 appears to be a much more compact system. As a DIYer, this was preferred, as shop space is valuable, and this will not be a workhorse piece of equipment. That said, I cannot imagine how a larger unit would be any better, except when it comes to the larger vials of the CT150. The instructions on this have much to be desired. I have seen repeatedly in the listing and instructions where it mentions "special fluid" for cleaning injectors. Still haven't the foggiest what this 'special fluid' is. Given the atomization of the liquid, and the heating and open tub of the ultrasonic, i did not want to use a highly volatile cleaner like gasoline or most of the gasoline injector additives. I've seen some use mineral spirits, but I chose to go with Kerosene because that's what I had on hand, and it is slightly less volatile than mineral spirits. I might take a look at Lucas injector cleaner as it is offered in a gallon size, but honestly, it seems like the Kerosene worked perfectly. I do have concerns with all of these units, and the method fuel is introduced to the rail. on both the CT150 and CT160, there is a single input into the fuel rail, and the pressure pulses significantly on high flow tests as the injectors pulse. This means that injectors further away from the input will see dips in pressure that could give a false reading. The CT150, given its two rod design, means the input is centered in the fuel rail and would suffer less from this issue. However, the CT160, since it has a single rod in the middle, means the input has to be offset, and is placed between the 3rd and 4th injector position. While I have not verified this yet, I would expect to see position 1 suffer in the manor when running high flow tests. Long term, I will most likely add a T fitting to the input hose and create a second input in the fuel rail between positions 1 and 2 to balance the fuel pressure. This may be a non-issue for most, but if you are trying to match injectors for a performance build, this should be considered. Finally, some have complained about how messy the unit is when taking out the injectors. If you fashion a method of introducing air into the fuel rail and then running the ultrasonic selection on the menu, the system will pulse the injectors without activating the pump. You will need to introduce air above the injectors however, otherwise the vacuum will keep the fluid from flowing through the injectors.
Review: Works good - Good so far, test functions are decent. Ultra sonic cleaning works good too.

## Questions & Answers

**Q: How to choose test fluid?**
A: The test fluid assesses the fuel injector’s performance. Recommended using a professional automotive injector test fluid. If not available, medical alcohol with more than 75% alcohol content can instead.

**Q: How to choose cleaning fluid?**
A: To clean deposits (such as carbon deposits) on fuel injectors, use a cleaning fluid that is highly corrosive and flammable. For the best testing results, opt for a professional injector ultrasonic cleaning fluid. Such as brand 3M and Lucas.

**Q: Can l use cleaning liquid to test the injectors?**
A: ABSOLUTELY NOT NOT NOT! The cleaning liquid is corrosive and may damage internal machine components, corroding rubber and causing leaks.

**Q: What if the cleaning fluid is mistakenly added to the test and the pump is broken?**
A: Please cont-act us and we will send the replacement pump to you for free, if it is within the 3-year warr-anty period.

**Q: Can diesel injectors be cleaned and tested by CT160 fuel injector cleaner tester?**
A: CT160 Heated Injection Systems Cleaners Testers can clean diesel injectors, but not test.

### ⭐⭐⭐⭐⭐ Works good
*by E***. on 28 February 2026*

Good so far, test functions are decent. Ultra sonic cleaning works good too.

### ⭐⭐⭐⭐⭐ Expensive machine, but a great way to clean and check your fuel injectors.
*by D***. on 23 January 2025*

I purchased a car that had not run in 24 years. I replaced and cleaned as much as I could with regard to the air, fuel and spark systems before even trying to turn the engine over. Part of that was dealing with the fuel injectors. This machine made is incredibly easy to clean the injectors and then test them. As it turned out 1 injector out of 4 was marginally more leaky than the others. Good to know and who knows, at some point I may replace it. But I was very happy when the car turned over and ran beautifully on just the second turn of the key! The machine is somewhat expensive, but I will use it to clean and check the injectors on my 4 other cars.
