EVANS Coolant EC10064 NPG Waterless Engine Coolant, 64 fl. oz.

**** NPG coolant has garnered a mix of reviews from customers, highlighting its long-lasting performance and significant benefits for engine cooling in various applications. Many users have reported remarkable experiences, particularly in high-performance settings, such as in off-road motorbikes and older cars. One long-time user noted that he has maintained two vehicles with NPG for over a decade without needing a replacement, indicating the product's durability and effectiveness. For dirt bike enthusiasts facing overheating issues in challenging environments, such as high altitudes, NPG has proven to be a game-changer. Users have reported successful temperature management and even extended engine life. One customer, after using this coolant in a KX100, celebrated the resolution of overheating issues that had been persistent. Similarly, another user found an impressive doubling of piston life in their KDX220 after switching to NPG. However, not all experiences have been positive. A particularly critical review indicated that using NPG in an XR650R resulted in significant temperature increases, leading to engine concerns. This stark contrast in performance has raised questions about the coolant's compatibility with certain bike models, suggesting that while it excels in many situations, it may not be universally beneficial. Overall, NPG coolant is celebrated for its corrosion resistance and longevity, particularly among older vehicles and certain dirt bikes. Yet, potential buyers should be cautious and perhaps research their specific vehicles more thoroughly to ensure compatibility, given the mixed reviews regarding performance in some situations. **
