About four months ago I bought a quart of Lucas Upper Cylinder Lubricant and Injector Cleaner and began dosing my 2016 Jeep Wrangler (75K miles on it) with each tank full of fuel. After about 4 months I had a fuel injector fail. I replaced the faulty fuel injector (did all of the injectors) and got the vehicle back on the road, but since then I can’t get over the association of using the Lucas UCL and then having the fuel injector fail. I quit using it. Am I crazy to associate the two?

It would be helpful to know how the injector failed. Did it wear out, did the coil fail, did it stick?
I have no idea what state it was in. I had only the OBD codes indicating that Cylinder 4 injector open circuit and a misfire for that cylinder. Is there a way to physically examine the injector and know that state it was in?
I don’t know how common the injector problems are for the Pentastar 3.6; however, forum posts would get you to think that oil cooler leaks are a very common problem. The valley on my engine was dry - no oil cooler leaks.
Open circuit might indicate that the winding inside failed. If that's the case, it is not likely due to the additive.
That makes sense. Thank you for the reply.
