Considering today’s ever improving diesel engines, our Members have been asking which grade of diesel should they choose at the pump.
NRMA Motoring Advice recommends the Low Sulphur grade Premium Diesel option, as this is the only type of fuel that is compatible with today’s diesel fuel systems.
In older vehicles, the usage of regular diesel can cause significant sulphuric acid build up which quickly corrodes piston rings, cylinder linings, valves and cylinder head. Oil changes are also required frequently, doubling the vehicle’s manufacturer recommendations.
For newer vehicles, high pressure diesel direct-injection systems such as common rail diesel engines are highly sensitive to high sulphur fuels. Also, electronic metering systems are rendered inaccurate by deteriorating fuel injector pins.
Overall, high sulfur fuels increase vehicle repair and maintenance costs are for both vehicle types. Low sulphur diesel can be used in any vehicle or stationary diesel engine that currently runs on regular diesel.
Low sulphur diesel summary:
- Reduces sulphur in fuel potentially reduces the risk of corrosive wear in the engine;
- Reduces the sulphur content does not inhibit engine performance; and
- Reduces sulphur facilitates the introduction of new diesel exhaust treatment catalyst which will further enhance the reduction of environmentally sensitive diesel emissions;
- Reduces the ultra fine particles from diesel engine exhausts will improve local air quality;
- Reduces sulphur dioxide emissions, which contribute to acid rain, will reduce the risk of acid rain occurring.
Are you a regular user of low sulphur diesel? Have you noticed any improvements to your vehicle’s running and repair costs?
