What is TBN oil analysis?
For years, Total Base Number (TBN or BN) has been used as one of the key measurements in the field to help determine remaining oil life by indicating the amount of performance-related additive left in the engine oil. In short, it helps you know when engine oil needs to be changed.
What will be the effect or impact of high TBN lube oil on the engine components?
High TBN oils can produce high ash content that can impair engine efficiency and cause loss of power, this will lead to excessive deposit build-up on pistons and valves.
Is a higher TBN better?
Total Base Number (TBN) 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 TBN & Tan of oil?
TBN stands for Total Base Number, while TAN is short for Total Acid Number. Both of the tests monitor the effective life of in-service lubricants. The terms for “Total Base Number” and “Total Acid Number” are generally outdated terms and the test are currently designated as Base Number, or BN, and Acid Number, or AN.
What is high TBN oil?
The higher the TBN value, the more reserve alkalinity or acid neutralizing ability the oil contains. The alkalinity compounds are used to fight against organic, sulphurous and sulphuric acids formed in the oil.
What is a good oil analysis?
So for an oil to be classified as ISO 100, the viscosity must fall within 90 to 110 centistokes (cSt). If the oil’s viscosity is within plus or minus 10 percent of its ISO grade, it is considered normal.
What do oil sample analysis look for?
The lab will also look at the additives in engine oils, such as zinc, phosphorous, calcium and magnesium. If parts per million (PPM) levels are consistent, it’s a good sign the oil is not experiencing cross-contamination. The presence of wear metals, such as iron, copper or tin, provides evidence of equipment wear.
What is TBN TBN Test Kit and describe how it is used?
Description. MARICHEM T.B.N. TEST KIT is specifically developed for the determination of T.B.N. –value (alkalinity) of engine oils. It is an exceptional tool for an engineer onboard when it is necessary to check for additive degradation, additive depletion and oil grade.
What is TAN and TBN oil analysis?
TBN and TAN—What does it Mean? You may have seen or heard the terms TBN or TAN being used. TBN stands for Total Base Number, while TAN is short for Total Acid Number. Both of the tests monitor the effective life of in-service lubricants.
How do you read oil sample results?
In your oil analysis report, an acid number reading and base number reading indicate the level of acidic or basic properties the substance has. An acid number that is too high or low may indicate oil oxidation, an incorrect lubricant or additive depletion.
