Synthetic diesel engine oil

Researchers at ExxonMobil have developed an advanced lubricant for heavy-duty diesel engines.

Operators of heavy-duty diesel engines continue to express interest in extending the distance traveled and time between engine service intervals to reduce vehicle downtime and increase the overall profit contribution of each piece of equipment. Extending oil-drain intervals also lowers purchasing costs for engine oil and filters, labor costs to conduct scheduled maintenance, and disposal costs for used oil and filters.

Oil-drain interval extension must be carefully monitored and a suitable high-performance lubricant used to ensure that engine durability and reliability are not diminished, thus negating the monetary benefits of extending the oil-drain interval. According to ExxonMobil, the choice of an appropriate extended-service lubricant is particularly critical for modern low-emissions diesel engines, which expose the oil to a more severe operating environment.
