Fuel Injector Cleaners and Polyether-amine

by FTE Published on Friday, September 2nd, 2022

Back in 2008, I was the first to publicly highlight the significance of PEA (polyether-amine) chemistry for fuel system cleaning. Since then, polyether-amine has become one of the most discussed topics across automotive forums and websites. Before that, almost nobody outside the additive industry had heard of it.

PEA remains the most effective detergent chemistry for removing carbon deposits from the combustion chamber and the high-temperature areas of the fuel system. Results are often immediate, with noticeable improvements in engine performance within just a few miles after treatment, especially where injector or combustion-chamber deposits have accumulated.

To be fair, cheaper treatments based on polyisobutylene-amine (PIBA) can do a decent job of cleaning conventional port fuel injectors, much like any basic solvent-based cleaner. Where they struggle is with modern high-pressure fuel systems and the stubborn carbon that forms inside the combustion chamber. The reason most products avoid using PEA is simple: high-quality polyether-amine costs significantly more than these alternative chemistries.

More advanced products will use multiple cleaning technologies, such as Oilsyn’s PEATeach Petrol Dr, CarbonCode Diesel Dr, and CarbonCode DPF & Turbo Cleaner. They use modern cleaning chemistry combined with PEA and other cleaning functions to deliver a more thorough clean throughout the system.

Hello I misfueled my car (ford fiesta 2012 1.25 zetec petrol) with unleaded diesel. When i started to feel misfiring and noise, i staight up went to mechanic. They leaked the diesel out of the system and they changed the fuel filter. after finishing letf over petrol, i fulled the tank with E5. The problem is that it is still misfiring at ramps and low RPMs and fuel economy has worsened down. I dont really want to change the injectors and spark plugs.

I am trying to find a good additive. If i use PEA added product, will it solve the sticky diesel remnants?

Your answer is much appreciated.

Hello. With the Honda Civic 1.7 diesel and 185,000 km, what would you recommend? Use the AR6900-D MAX in another identical car, just a small bottle. It was a short time but I think it went well.
Now for this car, what advice do I have to make it last and run clean and well?
Thank you.
