- For many bearings, a good bearing seal is essential. Bearing seals perform a dual function by keeping lubricants from leaking out while preventing impurities from entering your parts. Both procedures can help your bearings last longer, but choosing the proper seals for your components is critical. Different types of bearing seals include:
- Over time, spark plug wires can deteriorate due to heat, moisture, and wear and tear. This can lead to misfires, rough idling, and decreased fuel efficiency. It is important to regularly inspect and replace spark plug wires as needed to maintain the overall health and performance of the engine
spark plug wires. - Spark plugs, as the name suggests, create a spark that ignites the air-fuel mixture inside the engine's combustion chamber. They are designed to withstand extreme temperatures and pressures, ensuring consistent performance. The primary components of a spark plug include a central electrode, a ground electrode, a ceramic insulator, and a metal shell. These parts work together to generate the spark required for combustion.
Oil seal performance is affected by not only the type and material of the selected oil seal, but also a variety of other factors, such as operating conditions, total eccentricity, rotational speed, the substance to be sealed, and lubrication conditions.
Figure 9 shows items relating to oil seal characteristics.


Power steering oil seals are integral to the functionality of the vehicle's power steering system. These seals are responsible for containing the hydraulic fluid within the power steering mechanism, preventing leaks and maintaining the smooth operation of the steering components. Power steering oil seals contribute to the proper functioning and longevity of the steering system, ensuring precise and responsive vehicle control.
Detergents: This additive isn’t like your laundry detergent! It focuses on preventing deposits, rust, and corrosion from forming on the piston ring area, piston under-crown, and other surfaces that tend to overheat.
Regardless of how many (or how few) miles you have on your vehicle, regularly scheduled oil changes are critical for keeping your car running newer, longer. When you head in for your next oil change at a nearby Firestone Complete Auto Care, ask your technician about a high mileage oil change, especially if you’ve observed oil stains in your driveway or heard engine rattling. A high mileage oil change could help your car hit its next big milestone!
Oil seals can also be known as rotary shafts seals, shaft seals, lip seals, elastomeric seals, and more.
