The exact number of miles a semi diesel engine can go with synthetic oil depends on several factors, including the specific engine model, the quality of the synthetic oil, and the operating conditions. However, in general, semi diesel engines can go significantly farther with synthetic oil than with conventional oil. Some estimates suggest that synthetic oil can extend engine life by up to 50%, which could translate to an additional 250,000 to 500,000 miles for a semi truck that averages 100,000 miles per year.
Is it recommended to use synthetic oil in a semi diesel engine?
Yes, it is generally recommended to use synthetic oil in a semi diesel engine. Synthetic oils offer several advantages over conventional oils, including:
* Improved fuel efficiency: Synthetic oils can reduce fuel consumption by up to 5%.
* Reduced emissions: Synthetic oils produce fewer emissions, which can help to reduce air pollution.
* Extended engine life: Synthetic oils can extend engine life by up to 50%.
* Better protection against wear and tear: Synthetic oils provide better protection against wear and tear, which can help to keep your engine running smoothly for longer.
* Improved cold-weather performance: Synthetic oils flow more easily in cold weather, which can help to prevent engine damage during startup.
Overall, synthetic oils offer a number of benefits for semi diesel engines. While they may be more expensive than conventional oils, the potential savings in fuel costs, maintenance costs, and engine repairs can make them a worthwhile investment in the long run.
