Without an engine retrofit, the sample normally will be taken from the dipstick port via the drop-tube method or from the drain port during an oil change. These are only a few of the reasons why there isn’t much of a market for fluid analysis of passenger vehicles. However, one of ...
1300120 Infrared absorption analysis MOBIL OIL CORP 24 March 1970 [24 March 1969] 14130/70 Heading G1A A sample of oil from a sequence of samples is tested for its viscosity, metal content, and infrared absorption and the results are compared in a computer with evaluation criteria which may ...

40 ℃ viscosity increase 50% of 3# samples, usually allow diesel engine lubricating oil viscosity increases range from 15~20%, viscosity increases may lead to increased wear and oil temperature, fuel consumption, energy consumption, therefore, is also not a normal 3# Sample sample. 翻译结果4复...
Whether they have fleet vehicles or tractors, many operators will test their oil to see if they contain any antifreeze, soot, fuel, chrome, or other contaminants that can damage the engine and affect oil performance. What you find in an oil sample analysis allows you to determine whether to...
3. Results and discussion 3.1. Preliminary studies: attempt to quantify ethanol in lubricant oil using HS-GC-FID and ATR-MIR without sample pre-treatment The initial aim of this work was to obtain an analytical method to quantify ethanol in lubricant oil without sample pre-treatment. Two techni...
Predicted from experiments, 6:1 methanol molar ratio to oil is considered to be the optimal concentration for the production of biodiesel in the transesterification process. Using three trails, results were 94.5%, 93.8% and 96.20% [30]. Prediction of performance and emissions using L16 ...

Another example is if you have high TBN for long engine corrosion protection but weak 4 ball wear test results then you end up with engine wear but no rusting... still a bad choice. Your oil has to be strong in all aspects to be capable of preventing engine damage and it is a diffic...
Used oil analysis at 10,000 and 25,000 miles deemed the oil suitable for continued use, and he continued to run on the same oil. "I changed my full flow filter after the second sample was sent in," Anderson said. "The money I saved on oil alone in the first 25,000 miles paid fo...
