What Happens If You Go Too Long Without Oil Change?
If you delay oil changes in a heavy-duty diesel vehicle, the oil degrades and thickens, leading to increased engine wear, overheating, and reduced efficiency. This can cause significant engine damage, ultimately leading to costly repairs or engine failure. Regular oil changes are critical to maintaining optimal engine performance.
Does Synthetic Oil Last Longer?
Yes, synthetic oil does last longer than conventional oil. It's engineered to withstand higher temperatures and resist breakdown, allowing for longer intervals between oil changes. This makes it especially suitable for heavy-duty diesel engines, which operate under more demanding conditions, enhancing engine protection and performance over time.
