⭐⭐⭐⭐⭐ James Wilkins - Heavy Machinery Contractor
"Purchased the D16 Pro Model in February 2025 for our fleet of excavators. After 7 months of continuous use on rocky terrain and high-load operations, it’s outperformed our expectations. The 420HP output and 2,000 Nm torque handle tough digging cycles effortlessly. Despite being second-hand, the military-grade corrosion coating has held up well—even through winter moisture and dust. No major issues, just routine maintenance. A cost-effective powerhouse for serious construction work."Purchase Date: February 2025 | Usage Period: 7 months
⭐⭐⭐⭐☆ Maria Gonzalez - Logistics Company Fleet Supervisor
"We retrofitted three long-haul trucks with the D13 Advanced Model in October 2024. Now at 8 months in, fuel efficiency has improved by about 18% compared to our old Euro 2 engines, which matches the supplier’s claim. The Euro 3 compliance lets us operate legally in regional zones that require it. Only downside? The noise level is noticeable—around 75 dBA—but acceptable for industrial routes. With proper flywheel lubrication, rust hasn’t been an issue. Great value for budget-conscious fleets."Purchase Date: October 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Thomas Reed - Farm Equipment Mechanic
"Installed a used D7 Base Model on a vintage grain harvester in May 2025. Needed something reliable but affordable—this fit perfectly. At 336HP, it’s more than enough for field operations. The modular design made integration smooth; swapped out the fuel pump and upgraded the cooling system without hassle. Even with visible surface rust on the flywheel, the core structure is solid. After 3 months of harvest season use, no failures. For farmers maintaining older machines, this engine is a game-changer."Purchase Date: May 2025 | Usage Period: 3 months
⭐⭐⭐⭐⭐ Elena Petrova - Mining Operations Engineer
"Our site replaced two failing engines with the D16 Pro Models in January 2025. Working 16-hour shifts in abrasive, high-dust conditions, we needed durability above all. These engines deliver consistent 420HP+ performance and handle extreme thermal loads without overheating. The rust-resistant coating truly makes a difference—after 6 months, other engines show far more wear. Yes, there’s no warranty, but our team follows strict maintenance protocols, and so far, zero unplanned downtimes. Worth every penny for rugged environments."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐☆ Daniel Cho - Industrial Mechanic & Retrofit Specialist
"Used the D9b Base Model in a custom crane retrofit last December. After 7 months in service, it’s running strong. The modular configuration allowed us to swap pistons and tune the fuel system for variable load demands—something newer sealed units don’t allow. Biggest win? 20% faster component swaps during servicing. Flywheel had light rust on arrival, but cleaned up easily with anti-corrosion treatment. Not ideal for emissions-sensitive urban zones, but perfect for off-grid industrial use. Recommend for shops doing custom machinery builds."Purchase Date: December 2024 | Usage Period: 7 months

Markus Reinhardt - Industrial Diesel Systems Expert (15+ years experience)
"In my assessment, the D13/D16 series offers one of the most cost-effective retrofit solutions for aging construction and mining equipment. The combination of Euro 3 compliance, modular architecture, and proven durability makes these engines a smart choice—especially where budget constraints rule out new units. While noise and lack of warranty are considerations, their serviceability and torque output outweigh these for industrial users who maintain their own fleets."
Lena Fitzgerald - Commercial Vehicle Emissions Consultant
"For operators transitioning from pre-Euro engines, upgrading to Euro 3-compliant second-hand diesels like the D16 is a pragmatic step toward cleaner operations. Though not as efficient as Euro 6, they offer a 15–20% fuel improvement and 30% lower NOx emissions than older models—making them viable for regions with moderate regulations. Pair with regular maintenance and anti-corrosion care, and these engines can extend machinery life sustainably."
