Chickenman Posted August 27, 2015 Share #1 Posted August 27, 2015 Just a couple of suggestions on Fuel Injector cleaners that REALLY work. I've personally used these products on my 1998 Audi and 1976 280Z and can attest to their effectiveness. 1: Liqui Moly Jectron fuel injection cleaner. Liqui Moly is a German company that makes top quality Lubricants and other Automotive chemicals. Jectron works really well at cleaning injectors. Sometimes it takes 2 or 3 treatments, but it really cleans out gummed up injectors. Good as a regular maintenance product. 2: CRC 1-Tank Power Renew: CRC products are always good quality. I've tried this product and it really cleaned out my high mileage 280Z injectors. It's a bit pricey, so I use the CRC 1-Tank as an initial injector cleaner and then use the Liqui Moly Jectron as a regular maintenance product.

TomoHawk Posted August 29, 2015 Share #2 Posted August 29, 2015 (edited) So you're saying we shouldn't bother with the 99-cent bottles of (whatever) you get at the discount store that's labeled "Fuel Injection System Cleaner?"

Chickenman Posted August 29, 2015 Author Share #3 Posted August 29, 2015 (edited) Confucius say... Ya gets what yaz pay for.. I had my Audi A4 injectors Ultrasonically cleaned and flow tested at a local FI and Carburetor specialist. They had over 230,000 km on them. I have been using Jectron as a regular maintenance item for the last year or so. Owner was amazed out how clean the injectors tips were and how accurate the spray pattern was. Only thing he found wrong was that the individual injector filters ( very fine ) were clogged with debris... mainly rust and dirt particles. Injector cleaners can't dissolve that stuff. He installed new filters. When I told him about the Liqui Moly product, he was very interested as over the last 20 years he has found very few " Off the shelf " Injector cleaners that clean worth a darn. Jectron was the exception. He was sufficiently impressed that he was going to try it in his own vehicles. Edit: I've also tried the various el cheapo FI cleaners over the years. STP, Gunk, Wynns etc. They never seemed to make much difference.... . Edited August 29, 2015 by Chickenman Link to comment Share on other sites More sharing options...
Chickenman Posted August 29, 2015 Author Share #4 Posted August 29, 2015 (edited) ^ While these injectors were out I was running on a spare set of Injectors that I had bought off of E-Bay. They had " supposedly " been ultrasonically cleaned and tested. Tips looked clean, but #3 injector leaked badly from the get go. First start in morning was very rough, and I was actually concerned about fuel " Hydrolock" . Starter was laboring against accumulated fuel in bore. There was that much fuel leaking overnight and pooling in the Cylinder. Threw some Jectron in, and by the end of the first tank ( bottle ) engine was starting smoother. Buy the end of the second Tank ( bottle ) the hard and rough start problem had completely disappeared. Engine is silky smooth now. I'm sold!!

TomoHawk Posted August 30, 2015 Share #7 Posted August 30, 2015 If the stuff is so good, how come you can't get it at the local AP stores? I checked them all (Advance, Autozone, Oreilly's) but NAPA. Link to comment Share on other sites More sharing options...
Patcon Posted August 30, 2015 Share #8 Posted August 30, 2015 Let me get this straight, your opinion on whether a product is good or possibly the best is whether the cheapest parts suppliers in your area carry it???? They carry what is cheap because people want things a cheap as they can get them. That doesn't mean there isn't a better product out there. It's hard to sell a more expensive product if people don't see the value... but many times you get what you pay for... No offense intended.

gwri8 Posted August 30, 2015 Share #9 Posted August 30, 2015 Advance Auto carries the CRC 1 tank, I just bought some to try. The bonus was that it's on sale for $12 (normal 17.00). Seems really cheap to me considering the alternatives. If it performs as in Chickenman's experience, no matter the cost, it's still cheaper than new fuel injectors. This is kind of what I've been looking for on my wife's Honda and Son's Celica. I'll do them first before I do the Z. It got new FI's less than a year ago.

S30Driver Posted August 31, 2015 Share #10 Posted August 31, 2015 Read this post on super injector cleaners and decided to pit my personal choice (cheaper than seafoam by volume) against the CRC 1Tank. I'll let you know how it turns out .... 2 Link to comment Share on other sites More sharing options...
rcb280z Posted August 31, 2015 Share #11 Posted August 31, 2015 Please tell me your not sipping on the CRC 1 . I can buy the CRC 1 at AutoZone but haven't seen the liqui moly anywhere. Curious to know how well the CRC1 works. Link to comment Share on other sites More sharing options...
Captain Obvious Posted August 31, 2015 Share #12 Posted August 31, 2015 decided to pit my personal choice against the CRC I'll let you know how it turns out .... Haha!! Nice!
