This is a chemical change , replacing the filter won't reverse the condition. In the days of cheap oil the solution was to change often. Modern synthetic (expensive) oils make the 'chang-er-ever-3000 mil.' solution much less attractive. This is a non-trivial problem because if the oil becomes acidic enough it will begin attacking the metal parts inside the engine. There are oil analysis labs that will tell you to change the oil if it is becoming dangerously acidic. This is nice but avoids the basic problem , the oil isn't 'worn-out' it is just contaminated with dilute acid WANTED:(1) a HOME test kit to test the PH level of motor oil and (2) a kit with chemical additives (strong BASIC chemicals) to neutralize the acid to a safe PH level. And replace any anti-wear-foaming-oxidizer etc additives as needed. QUESTION: While it is certainly possible to neutralize an acid with a base , are there technical reasons preventing the modification of the PH of motor oil? eg will abrasive salts precipitate out of solution? Are the necessary chemicals too toxic for use by the general public? Have the big oil Co.s 'bought-up' the idea? Are there any lubrication engineers out there that can shed some light on this subject? Does anyone make this test & additive kit? And if so how can i get one?
