AA-Jintech – Cutting-edge energy solutions for optimised fuel consumption

Innovative Fuel & Energy Solutions

Reduce fuel costs, improve efficiency, and lower emissions with advanced nano-catalytic additives.

Our Story

In 2021, Associated Asphalt Contracting Limited (AACL), a leading UK infrastructure construction company, began exploring technologies to reduce its carbon footprint. Following a global search for innovation, AACL’s Chief Executive Officer identified Korea Jintech Co Ltd (KJTCL), a South Korean specialist in diesel fuel additives designed to reduce fuel consumption and emissions.

KJTCL’s fuel catalyst additives are designed to improve combustion efficiency and lower emissions. Following almost four years of extensive trials undertaken by AACL and supported by academic validation, AACL and KJTCL established a UK-based sales company to bring these solutions to a wider market. In 2025, AA-Jintech Limited was formed to build strategic partnerships and support customers across multiple sectors and regions, with the backing of AACL in the UK and KJTCL in South Korea.

Testimonials

"We are highly impressed with the excellent fuel-saving performance and emission reduction capabilities of the fuel additive. What surprised us the most was the greater-than-expected efficient improvements that led to significant fuel cost reductions and smoother engine operation, which also decreased our maintenance expenses."

"We received highly positive feedback from customers reporting notable fuel savings, as well as reduced engine noise, vibration and improved responsiveness. Particularly, the additive holds a significant value from an environmental perspective. It reduces particulate matter and harmful emissions , contributing to environmental protection and aligning well with Hyundai Motor's commitment to eco-friendly initiatives."

"Our practical experience showed an average of over 20% fuel savings, without any adverse effects on engine power of stability. Furthermore, we observed a significant reduction in soot and NOx emissions, which has been extremely helpful in meeting environmental regulations. To all potential global partners: try the additive, and you will certainly be satisfied. Its a choice you won't regret."

"We decided to purchase the additives and conducted extensive trials, independent testing, and academic studies. The results spoke for themselves. We’ve now fully adopted the additives across our operations and have achieved meaningful emission reductions along with circa 20% fuel savings. It’s been a transformative improvement for our business."
