The 4 Types of Engine Oil

oil being poured into an oil tank with title text the four types of engine oil.

What type of engine oil should you use for your vehicle? 

Full Synthetic Oil Change

Synthetic engine oil is created using man-made, controlled materials. Non-conventional, high-performance additives are used to increase the lubricant’s performance. Synthetic engine oils contain only smooth lubricating molecules, meaning:

  • they’re more effective at reducing friction, offering better fuel economy.
  • they provide lower volatility – the tendency of an oil to break down at extreme temperatures – for decreased oil consumption.
  • they flow through your engine easier, which makes for easier start-ups at very cold temperatures.
  • they reduce engine deposits – the “by-products” of engine combustion.
  • they offer greater viscosity (the “thickness” of an oil) at very high temperatures.
  • they’re more stable, meaning it will hold up for a longer period of time.

Synthetic oil is the most expensive of all oils because of their many benefits over conventional oil. However, you’ll need oil changes less frequently, saving you money over time. Synthetic oils are recommended for newer, high-performance vehicles.

Synthetic Blend Oil Change

Synthetic blend engine oils use non-conventional, high-performance fluid additives blended with conventional engine oil. This blend provides added resistance to oxidation and protects against the following:

  • stop-and-go traffic
  • cold start-ups
  • long engine running times
  • fluctuating/extreme temperatures

We recommend synthetic blend oil changes for cars, trucks, vans, and SUVs that regularly carry heavy loads, tow trailers, or operate frequently at high RPMs.

High-Mileage Oil Change

This is a special blend of oils and additives that are designed to extend the life of higher mileage vehicles. High-mileage means more wear on your engine, so they demand a powerful concoction that will protect against:

  • oil burn-offs
  • engine leaks
  • engine deposit build-up
  • sludge
  • friction

Recommended for vehicles with more than 75,000 miles on the odometer or over 15,000, per year.

Conventional Oil Change

Also known as mineral oil, conventional engine oil is made from crude oil pulled from the ground and processed at a refinery. The product is a base oil that’s combined with additives to enhance:

  • engine protection properties
  • heat breakdown capabilities
  • viscosity (the thickness and fluidity of the oil)

Conventional oil is typically the least expensive of all oils and doesn’t have the additives to make it more durable and long-lasting.

  1. Hi“ If you are willing to drive routes that are dangerous, or carry expensive or dangerous loads, you will be compensated accordingly. These trucking jobs aren’t for everyone, and you must have a specialized skill and knowledge base. You must also be comfortable with the risk. Here are some prime examples of trucking jobs that pay more for the associated risks and requirements.

  2. This was so educational. I’ve been wondering what type of oil would be best to use for my vehicle. It makes sense why synthetic oil is the most expensive. I feel like the benefits, like needing fewer oil changes, are worth it.

  3. Always try to use synthetic engine oil for your car which is bit expensive than the others but it will greatly reduce your maintenance cost. It provides better lubrication and improves the life span of the engine. Remember the synthetic oil also has a tenure after which it has to be drained out and replaced or else it may cause engine problems.
