Conquering the K2K: A Fuel Efficiency Odyssey Through India

Have you ever dreamt of a road trip that stretches across the entire breadth of India? A journey that tests your endurance, exposes you to breathtaking landscapes, and lets you experience the country's vibrant tapestry of cultures? Buckle up, because we're about to embark on exactly that adventure, with an added twist: a quest to improve fuel efficiency.

Fossil fuels are a precious resource, and with prices constantly on the rise, saving money at the pump is a priority for many drivers. While electric and hybrid vehicles are gaining traction, there's a certain charm to the internal combustion engine (ICE) experience that many just can't resist. So, we set out to explore an alternative - performance additives that promise to boost both efficiency and power.

We opted to bypass the typical closed-circuit tests and headed straight for the real world. Our chariot for this epic journey? A quartet of Hyundai vehicles - two Tucson diesels and two Exter petrols, one automatic and one manual transmission in each pair. Our destination: Kanyakumari, the southernmost tip of India, to Kashmir, nestled in the foothills of the Himalayas, a distance of roughly 3,000 kilometers. Scenic detours and unexpected obstacles were all part of the adventure.

The secret weapon in our arsenal? Milex, a performance additive by Dorf Ketal Chemicals. Their claims were bold: a 10% improvement in fuel efficiency. We were determined to put those claims to the test.

Our journey began amidst the confluence of the Arabian Sea, the Bay of Bengal, and the Indian Ocean. After filling up all four vehicles at Nagarcoil, we introduced a 50ml dose of Milex into one Tucson and one Exter. The first leg took us towards Bangalore, cruising along scenic highways with gentle elevation changes.

As we ventured into the bustling city of Bangalore, India's Silicon Valley, we started noticing a trend. Data indicated a increase in efficiency for both Milex-treated vehicles. The Exter with Milex showed a 4.5% improvement, while the Tucson fared even better with a 6.4% jump.

The road from Bangalore to Mumbai was a long, mostly straight stretch, allowing us to maintain a higher average speed. By the time we reached Lonavala, the data solidified our initial observations. Milex seemed to be making a difference.

Our next stop was Jaipur, the "Pink City," followed by Delhi, the capital of India. Here's where things got interesting. Milex primarily targets older engines, and our Hyundais were fairly modern. To even the playing field, we decided to enlist the help of a veteran - a Toyota Innova with a trusty diesel engine that had clocked several lakh kilometers. It's easy to guess why - dirtier and older the engine, more the improvements on account of cleaning and better fuel efficiency. This would be a true test of Milex's effectiveness on a seasoned campaigner.

As we pushed towards Punjab and began our ascent towards Srinagar in Kashmir, the breathtaking beauty of the Himalayas unfolded before us. Nestled amidst these majestic peaks lies Srinagar, its jewel-like Dal Lake shimmering with houseboats. The vibrant bazaars, fragrant gardens, and historic charm made it a fitting culmination to our epic odyssey.

But our journey wasn't just about the sights and sounds. By the time we reached Srinagar, we had gathered a wealth of data. Milex demonstrably improved fuel efficiency. The Innova, with its older engine, saw the most significant improvement - a remarkable 11.2%. The Tucson followed closely at 7.5%, while the Exter with Milex managed a 5.2% increase.

It's important to remember that real-world results can vary depending on driving style and road conditions. However, our K2K adventure provided compelling evidence that Milex can be a valuable tool for drivers seeking to improve fuel efficiency, especially for those with high kilometres on the clock. 

So, the next time you're planning a road trip, consider adding a dose of scientific efficiency to your adventure. After all, saving money at the pump means more miles you can conquer! Now, this fuel additive is specifically formulated to be more effective in older cars. It's not a magic bullet, but science backs its benefits. Vehicles with higher kilometres on the clock tend to accumulate carbon deposits in the engine over time. This additive helps clean those deposits, which can improve fuel efficiency in older vehicles.

City Slicker Showdown: Mumbai to Pune

Encouraged by the Kanyakumari-Kashmir findings, we decided to investigate Milex's effectiveness on shorter, everyday commutes. We enlisted a popular choice for city driving, a Toyota Yaris petrol, and its diesel counterpart, the Innova Crysta, for a Mumbai-Pune round trip, mimicking a typical city run. To mirror real-world driving conditions, the route encompassed a mix of highway stretches and bustling city traffic. We meticulously documented fuel efficiency figures for both cars. The first leg was completed without the additive, serving as a baseline for comparison. Subsequently, the recommended dosage of Milex was added to the respective fuel tanks, and the return leg was driven.

The Efficiency Edge in Action

The results were music to the ears of cost-conscious drivers. The Innova Crysta, known for its diesel efficiency, showed a significant improvement. Without the additive, it achieved a respectable 12.37 kilometers per liter (kmpl). However, with Milex added, the efficiency shot up to a commendable 17.13 kmpl, translating to a substantial 38.4% increase. This translates to real savings at the pump, especially for those who rack up the miles in city commutes.

The petrol Yaris also witnessed a noteworthy improvement. The initial run, sans additive, yielded a fuel efficiency of 18.31 kmpl. After introducing Milex, the efficiency climbed to a significant 21.76 kmpl, reflecting an 18.8% increase. These figures are a strong indicator that Milex's ability to enhance fuel economy extends across engine types, offering benefits to a wider range of drivers.

Beyond the Numbers: A Performance Perk

The benefits extended beyond just fuel efficiency. Our test drivers noted a perceptible difference in vehicle performance. Both cars exhibited better pickup, especially when tackling inclines. This translates to more responsive acceleration and a less stressful driving experience in stop-and-go city traffic. Additionally, the engines ran smoother, translating to a more pleasant driving experience overall. While the exact science behind Milex's performance improvements remains proprietary information, the additive appears to optimize fuel combustion. This likely leads to more efficient power generation, explaining the observed increase in fuel economy, smoother engine operation, and potentially a reduction in unwanted vibrations.

Real-World Implications for Drivers

The findings of this Mumbai-Pune test hold significant weight for everyday drivers. Milex's ability to demonstrably improve fuel efficiency, even on shorter runs, can lead to substantial cost savings in the long run. Consider a driver who commutes 20 kilometers daily; a 18.8% increase in fuel efficiency, like the one observed in the Yaris, could translate to significant savings over a year. Moreover, the enhanced performance translates to a more enjoyable driving experience, especially in the cut-and-thrust of city traffic.

Looking Ahead: Further Exploration

Our exploration of Milex is far from over. While this test focused on fuel efficiency and performance, future endeavors will investigate its potential impact on emissions and engine wear. We will also explore Milex’s performance across a wider range of vehicles and driving conditions. This could include testing different car models, fuel types, and terrains to get a more comprehensive picture of the additive's effectiveness.

The Final Word


The Mumbai-Pune trial serves as a compelling testament to Milex's effectiveness on shorter runs. The substantial gains in fuel efficiency and the noticeable improvements in performance are promising indicators of the additive's potential benefits for everyday drivers. What’s come across as a surprise, and a rather pleasant one, is seeing unreal gains in fuel efficiency than what is claimed by Milex, twice as much gains as being promised with the petrol and thrice as much with the diesel. As we delve deeper into Milex's capabilities, stay tuned for further insights in upcoming editions, where we'll explore its impact on emissions, engine wear, and its performance in a wider range of vehicles and driving conditions.
