Can Naturally Aspirated Cars Use Full Synthetic Oil?
2 Answers
Naturally aspirated cars can use full synthetic oil. Here are the reasons why synthetic oil is suitable for naturally aspirated vehicles: Synthetic oil performs better: Full synthetic oil features more stable base oil formulation, superior sludge resistance, and better fuel economy, thus providing enhanced protection for the car's engine. Synthetic oil lasts longer: Synthetic oil resists degradation, has low evaporation loss, and offers a longer service life than conventional oil. It exhibits excellent chemical stability, good radiation resistance, high oil film strength with minimal foaming, delivering superior lubrication and reduced wear.
Of course you can use it! My old naturally aspirated car has always been running on full synthetic oil, and the engine sounds noticeably quieter and smoother. The advantage of full synthetic oil lies in its excellent fluidity, especially for cold start protection—it quickly lubricates every corner of the engine as soon as you start it, which is crucial in winter. Plus, its superior cleaning power helps reduce carbon buildup. Although it's more expensive, the maintenance interval can be extended to around 10,000 kilometers, making it more cost-effective in the long run. Just make sure the oil viscosity meets the manufacturer's manual requirements—don’t just focus on the brand. Grades like 5W-30 are most common for naturally aspirated engines. Regularly checking the dipstick is also a must; if the oil turns black or thin, replace it promptly.
