What is high TBN oil?
Total Base Number (TBN), is a property that measures oil’s ability to neutralize acids formed during engine operation. Generally, oils with a higher TBN better neutralize acids and combustion by-products, resulting in longer oil life and improved protection against corrosion.
What is the major disadvantage of synthetic oil?
Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.

What is a good TBN number?
The TBN of fresh oil is typically in the range of 7 to 10 for gasoline engines and 10 to 14 for diesel engines. If the TBN drops to a point where the oil can no longer neutralize acids, usually around 3, it normally indicates it is time for an oil change.
What is a good TBN number in oil?
Without this base reserve, strong acids accumulating inside the engine can result in corrosive wear. Generally, a TBN value for a new engine oil can range anywhere from about 6.0 – 13.0 mgKOH/g. For decades, it has been used as more or less an industry standard for determining when engine oil should be changed.
