To check if the oil has lost its viscosity, you can use two methods. How You Can Check if the Oil Has Lost Viscosity

If the oil is dark in color, but still fairly fluid and clean - then it is probably still usable, and it is quite good quality. There should also be no individual dark spots, the oil trace should be uniform. There should not be small black dots in the trace, which are metal domes. The oil should not be very thick and extremely dark (like oil). This is the trace that you should look at closely.

Part of it will be absorbed into the paper, and the rest will spread on the paper surface. If during rubbing you hear a metallic squeak or crunch, and moreover you feel the mechanical impurities, it means that there are chips or the oil filter is worn (it can't filter).Īnother simple test is to put a sheet of clean paper at an angle of 30° to 45° and drop a couple of drops of the oil being tested on it. The second way to check the presence of foreign impurities is to drop a couple of drops on a small piece of glass and rub it over the surface with the second piece.

The easiest way to How to Perform Oil Analysis and see if your engine parts are critically worn is to take 30 grams of oil from your engine and put a magnet in it. If you regularly use the drip method every 3,000 miles (saving the results), you can track changes in the condition of both the oil and the engine itself. Both methods allow you to quickly find out the condition of your oil and engine at home. And to do such a drip test you will need about half an hour (but more accurate results appear after 24 hours) and a blank sheet of A4 paper (will cost nothing) or a few packaged one-drop test kits designed for field-testing oil, which will cost $15-$20 ($20 for a six-sample kit, and a refill is $15).

These can be identified by paper chromatography. Most changes in chemical composition lead to physical changes. The test will take two to four days and the results will show a lot of useful information about internal wear and contamination, changes in chemical composition and physical properties. The cost of an oil test kit ranges from $25 to $50. How much does it cost to have engine oil analyzed?
