Alkaline reserves
Alkaline reserves refer to the ability of an engine oil to neutralize harmful acids produced during combustion. This property is measured by the Total Base Number (TBN), which indicates how effectively the oil can break down acidic contaminants. Especially in diesel engines, which produce more sulphuric acid and other corrosive residues, alkaline reserves play a crucial role.
Why are alkaline reserves important?
A high TBN value means that the engine oil has sufficient alkaline reserves to protect the engine from corrosion, deposits and oil oxidation. BASINOL engine oils are specially formulated to provide an optimum balance of acid neutralization and oxidation protection. This ensures longer oil change intervals and improved engine performance, especially in commercial vehicles and industrial lubricants for heavy-duty applications.learn why alkaline reserves in engine oil are essential for acid protection. All about TBN values & protection for engine & transmission.
How can I tell whether my engine oil has sufficient alkaline reserves?
The TBN value is measured in milligrams of KOH per gram of oil. A new value is often between 7 and 12 for passenger car oils and over 12 for commercial vehicles. BASINOL engine oils offer optimally adjusted TBN values for various applications.
What happens when the alkaline reserves in the engine oil are used up?
If the alkaline reserves are used up, the oil can no longer neutralize acids. This leads to corrosion on metal parts, sludge deposits and accelerated oil degradation. A timely oil change with a high-quality BASINOL oil prevents these problems.
Do all engine oils have alkaline reserves?
Yes, but in varying concentrations. Low SAPS oils often contain lower quantities in order to protect modern exhaust aftertreatment systems. Commercial vehicle and heavy-duty oils, on the other hand, require high TBN values for long operating times and demanding conditions.
