What Does Dexos Mean On Engine Oil?

“Dexos” is a set of specifications developed by General Motors (GM) for engine oils. Dexos is General Motor’s proprietary dealer bulk oil. Engine oils that meet the Dexos1 spec are designed to provide optimal performance, protection, and fuel efficiency for GM vehicles. 

These oils undergo rigorous testing to ensure they meet GM’s standards and API certified. Using Dexos1 oils can help maintain the performance of your GM vehicle.Currently it is manufactured by exxon mobil. 

Is Dexos Oil The Same As Synthetic Oil?

Dexos oil and synthetic oil are not the same thing, but there is a relationship between them. Dexos is a specification for engine oil that is designed and licensed by General Motors (GM) for use in their vehicles. 

It was introduced to ensure that the oil used in GM engines meets specific performance and quality standards. Dexos oil can be either a full synthetic oil or a synthetic blend (also known as a semi-synthetic oil).

Synthetic oil, on the other hand, refers to a type of motor oil that is made using a highly refined and engineered base oil, along with a carefully formulated set of additives. Synthetic oils are known for their superior performance in extreme temperatures, improved lubrication, and enhanced protection against engine wear and sludge buildup.

So, to answer your question, Dexos oil can be synthetic oil, but it can also be a synthetic blend. It must meet the Dexos specifications set by GM, which include performance requirements and testing standards. 

If you are using Dexos-licensed oil in a GM vehicle, you can be confident that it meets the manufacturer’s requirements for that specific engine. If you are unsure about which type of Dexos oil to use in your GM vehicle, it’s best to consult your owner’s manual or contact a GM dealer for guidance.

Factors to Consider

1. Vehicle Specifications

Your vehicle’s make, model, and year are critical factors in determining the right Dexos oil equivalent. Consult your owner’s manual for specific oil recommendations tailored to your engine.

Consider engine oil of the appropriate viscosity grade (e.g., 5W-30 or 10W-40) required by your vehicle. The right viscosity ensures proper lubrication and engine protection in different temperature conditions. 

3. Additive Package

Examine the oil’s additives, which play a vital role in preventing engine wear and deposit formation. Look for oils with detergents, anti-wear agents, and antioxidants for enhanced protection.

4. Synthetic vs. Conventional

Decide between syn and conventional Dexos oil equivalents. Synthetic oils offer superior performance and protection but may come at a higher price point.

5. OEM Recommendations

If in doubt, follow the recommendations of your vehicle’s manufacturer. Using a Dexos oil equivalent that meets or exceeds their specifications ensures you’re in compliance with warranty requirements.

6. Budget and Usage

Consider your budget and how you use your vehicle. If you drive in demanding conditions or plan to keep your vehicle for an extended period, investing in a high-quality Dexos oil equivalent may be a wise long-term choice.

How to Change Your Engine Oil 

Step 1: Gather Your Supplies

Collect the necessary items: a new oil filter, the correct type and amount of engine oil, an oil filter wrench, a wrench for the oil drain plug, a funnel, and a drain pan.

Step 2: Prepare the Vehicle

Park on a level surface, engage the parking brake and let the engine run for a few minutes to warm the oil. This makes it easier to drain.

Step 3: Drain the Old Oil

Locate the oil drain plug beneath the engine, place the drain pan underneath, and use the appropriate wrench to loosen and remove the plug. Let the old oil drain completely.

Step 4: Replace the Filter and Refill

Remove the old oil filter, apply a small amount of new oil to the rubber gasket of the new filter, and screw it in by hand. Tighten it an additional 3/4 turn. Then, use a funnel to pour in the recommended amount of new oil. Replace the oil cap and check for leaks before disposing of the old oil properly.

How Do I Know If My Oil Is Dexos Approved?

To determine if your engine oil is Dexos approved, you can check the oil container’s label, consult the manufacturer’s specifications, or use online resources. Here are steps you can follow:

Check the Label

Look at the label on the oil container. If the oil meets the Dexos specification, it should clearly state “Dexos Approved” or “Meets Dexos Specifications” on the label. It might also display the Dexos logo, which consists of the Dexos name and a GM (General Motors) logo.

Consult Your Vehicle’s Manual

Your vehicle’s owner’s manual or maintenance guide may specify the type of oil that is recommended or required for your engine. If it mentions Dexos or a specific Dexos specification (e.g., Dexos1 or Dexos2), then you should use oil that meets those specifications.

Visit the Oil Manufacturer’s Website

Many oil manufacturers provide information about their products and their Dexos approval status on their websites. You can search for the oil brand and product you’re using or interested in and check if they mention Dexos approval.

Contact the Oil Manufacturer

If you can’t find the information you need on the label, in your vehicle’s manual, or on the manufacturer’s website, you can contact the oil manufacturer’s customer support or check if they have a customer service hotline. They should be able to provide you with information about their product’s Dexos approval status.

Maintaining Engine Health Recommendations

Maintaining the health of your vehicle’s engine is crucial for its long-term performance and reliability. Here are some recommendations to ensure the engine’s well-being:

Change the Oil and Filters Regularly:
