Oxidation Inhibitors and Aging Stability
WARNING: This page does not describe the selected car, but rather 180 other vehicles, including the 2014 BMW i8, 2014 BMW i3, 2014 BMW Z4, 2014 BMW X6 M, and 2014 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.
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.
