Is a low sulphur diesel that contains 50 parts per million of sulphur which is much lower than the regular diesel 500ppm. The low sulphur level enable the product to be compatible with emission control devices such as catalytic converters and diesel particulate traps designed to operate at this low sulphur level. Reduced Sulphur content result in the absence of aromatic content in diesel thus reducing the lubricity of diesel. Continuous use of diesel 50 reduces maintenance cost due to insignificant contamination of engine oil therefore service interval can be increased. Diesel 50 is currently being offered at selected service stations.
