Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Oxidation Inhibitors and Aging Stability
Oxidation can be described as the oxygen absorption of hydrocarbons formed in the oil. The results of oxidation have a negative impact on viscosity causing corrosion on certain metals and the formation of sludge. Inhibitors are added to prevent oxidation from occurring. A good engine oil must maintain its stability during the required oil change intervals.
Good Lubricating Oil Must:
- Lubricate moving parts to minimize wear.
- Lubricate moving parts to minimize loss from friction.
- Remove heat from engine parts by acting as a cooling agent.
- Absorb shocks between bearings and other engine parts, reducing engine noise and extending engine life.
- Form a good seal between piston rings and cylinder walls.
- Act as a cleaning agent.
