Engine Oil - Everything You Need To Know

Engine Oil - Everything You Need To Know | Inmon Automotive

When it comes to maintaining your vehicle's performance and longevity, one of the single most important factors is its lifeblood: engine oil. A vital lubricant, it plays a critical role in ensuring the smooth and efficient operation of your car's engine. With numerous products on the market and varying advice from experts, understanding the essentials of engine oil can save you time and money, as well as ensure your vehicle stays in top condition.

What is Engine Oil?

Engine oil is a specialized fluid designed to lubricate internal combustion engines' moving parts like pistons, camshafts, and valve trains. It performs multiple functions: reducing friction between metal components, protecting against wear and tear, cooling engine parts by absorbing heat away from moving pieces that could potentially weld together or warp under high temperatures.

Types of Engine Oil

There are three main types of engine oils available:

Conventional Oil
Derived from crude oil with various additives to meet basic lubrication standards.

Synthetic Oil
Made from chemically modified petroleum components with more uniform molecular sizes, resulting in better performance characteristics at high temperatures and extended lifespans.

Synthetic Blend
A middle-ground option that mixes conventional base oils with synthetics to offer improved resistance to oxidation at a lower cost than fully synthetic oils.

Choosing the right type depends on manufacturer recommendations, driving conditions, and mileage on the vehicle, amongst other aspects.

Viscosity Ratings

Viscosity measures an oil's resistance to flow at specific temperatures; simply put—it dictates its "thickness." Multigrade oils carry labels such as 5W-30 or 10W-40 where 'W' stands for winter (not weight as commonly misconceived), denoting an oil's viscosity at cold temperatures (the lower number before 'W') versus hot (the higher number following 'W'). Higher viscosity ratings generally mean a thicker oil while lower suggests a thinner formulation suitable for cold starts because it flows more freely at low temperatures.

When To Change Your Engine Oil 

Gone are the days when standard advice was every 3 months or 3,000 miles whichever comes first. Advances in auto technology along with higher-grade oils have lengthened these intervals significantly—however exact recommendations vary by car make-and-model so check your owner's manual for guidelines specific to your vehicle.
Sensors can signify when it's needed also depending on your driving style: stop-start city driving tends to break down oil quicker than steady highway cruising does, leading to more frequent changes.

Reasons To Not Skip Or Delay an Oil Change

Knowing why regular changes are necessary may encourage timeliness—here's why:

  • Dirty or old oil risks pushing fine debris through an unprotected engine, causing potential damage.
  • Efficiency decreases as engines labor harder against ineffective lube, compromising fuel mileage.
  • A well-lubricated mechanism reduces strain, thus prolonging overall motor life, meaning you avoid costly replacements down the line.
