Engine oil plays a critical role in the longevity of the life of your vehicle’s engine.

The engine is the heart of the car and it needs to be kept healthy to ensure your vehicle’s longevity. The motor oil in your engine is the lifeblood of your automobile. As your engine runs, the oil breaks down, causing it to lose some of its friction-reducing properties and making it less effective. Moreover, it will pick up foreign particles, dirt and, over time, will become a sludge-like substance.

​Engine Lubrication

The internal moving components of the car engine requires proper lubrication at all times to work efficiently. The intent of the lubrication is to minimize friction. Incorrect lubrication will generate unnecessary friction that leads to increased amount of heat and the parts will wear out faster. Eventually, this will result to costly repairs.

Types of Motor Oil

Simply put, engine oils are formulated by blending base oils and additives to achieve the desired performance of the engine. However, engines have different performance expectations and characteristics resulting in oil companies manufacturing multiple types of oils. There are five general types of motor oil:

  • Conventional
  • Full Synthetic
  • Synthetic Blend
  • High Mileage
  • Diesel

At Autopractor, carry all five types of motor oil as well as different viscosities for each type of oil.

Conventional Motor Oil

Conventional motor oil is a very common type of oil. The oil is derived directly from crude oil. Typically, Light-duty cars with average or low mileage utilize this oil. Typical oil change intervals with conventional oils are at 3,000 miles.

Full Synthetic Motor Oil

Full synthetic motor oil is typically for higher performing engines. This oil resists breaking down, can withstand higher temperatures, and more effectively flows at colder temperatures. Many European car manufacturers have been specifying full synthetic oil for well over a decade. Many of the mainstream car manufacturers are starting to specify this type of motor oil. Typical full synthetic oil change intervals are between 7,500 to 10,000 miles.

Synthetic Blend Motor Oil

Synthetic blend motor oil is often said to be the best of both worlds between conventional and full synthetic motor oils. Full synthetic is a better choice when it comes to protecting the engine and ensuring the oil will not breakdown too far between oil changes. However, synthetic blend is more cost effective and is a superior alternative to conventional motor oil.

High Mileage Motor Oil

High mileage motor oils are developed with ingredients such as seal conditioners, detergents, and additives to help minimize wear as well as to reduce or even eliminate seepage or seal leaks.

Diesel Motor Oil

Diesel motor oil is intended for diesel engines. The major differences between diesel motor oil and gasoline motor is the additives and the viscosities. It is not recommended to use diesel motor oil in a gasoline engine.

Oil Level

Engine Oil Dipstick

The car’s engine oil resides in the oil pan which is bolted under the engine. The dipstick – typically has a yellow looped handle – extends into the oil pan to indicate the level of oil in the engine. The maximum and minimum engine oil level is specified by the limits of the crosshatch pattern near or on the bottom of the dipstick. Too much oil or not enough will be problematic for the engine.

Too little oil in the engine and you risk there not being enough for proper lubrication.  Too much oil and the excess oil will be pulled up into the spinning crankshaft. As a result, the oil will get aerated and have a foaming effect which will lower the oil pressure as the oil pump will be unable to effectively perform. In addition, the excess oil will ruin the seals and gaskets.

Oil does break down as the engine runs so it is strongly recommended the oil level be checked periodically.  Depending on your vehicle, you may need to add some oil between schedule oil changes to keep it above the manufacturer recommended minimum level.

Oil Filter

The oil filter removes tiny particles and contaminants from your oil. Without oil filters, the motor oil would become saturated with the impurities that can accelerate the wear on the surfaces and components of your engine.

The oil filter shall be changed during every oil change service. The filter itself is a pleated heavy paper medium. Once the filter is saturated with impurities, then the oil bypasses the filter during circulation no longer filtering out any additional foreign particles and contaminants.
