The main difference is that Euro5 diesel contains only 10ppm* of sulphur compared to 500ppm for Euro2M. It is therefore a much cleaner fuel which produces lower emissions for a cleaner environment. As a significantly higher grade diesel, it also extends engine life and improves fuel efficiency.
Sulphur in diesel creates particulate matter (PM) during combustion and the continued generation of PM causes health issues. In addition to environmental and health issues, the sulphur in the fuel also contributes to increased acid levels in the engine that can cause damage to engine and emission control systems. The presence of sulphur in the engine exhaust gases limits the effectiveness of many exhaust after-treatment technologies, resulting in higher emissions of other pollutants.
My question is, i have a 2012 toyota hilux with me. i had tried pump full tank twice with Euro 5 diesel. but i can't sense any significant different in accelerate or power. i know that if for cleaner environment, yes euro 5 is definitely better but do u think is worth it for my this car to use euro 5 or just maintain the normal diesel.
ya and i know the price different for both are just 10sen per liter but this is a heavy duty car which will have a high mileage driving.
Euro 5 Diesel vs Euro 2 (normal type), come give your thought
