Best Motor Oil For Hot Weather – Buying Guide

When it comes to choosing the best motor oil for hot weather, there are several factors to consider. Here are some things to keep in mind when making your selection:


Viscosity is a measure of how thick or thin the motor oil is. In hot weather, thinner oil is generally better because it flows more easily and provides better lubrication. Look for motor oil with a lower viscosity rating, such as 5W-30 or 10W-30.


Some motor oils contain additives that can help improve performance in hot weather. For example, some oils contain detergents that help keep the engine clean, while others contain friction modifiers that help reduce wear and tear on engine components.

Synthetic vs. Conventional

Synthetic motor oils are generally better suited for use in hot weather because they are more resistant to breakdown and can provide better protection under high temperatures. However, synthetic oils can also be more expensive than conventional oils, so it’s important to weigh the benefits against the cost.

API Certification

Look for motor oils that are certified by the American Petroleum Institute (API). This certification ensures that the oil meets certain quality standards and can provide adequate protection for your engine.

Other Considerations

Other factors to consider when choosing motor oil for hot weather include the type of engine you have, the driving conditions you typically encounter, and the manufacturer’s recommendations for oil type and viscosity. Be sure to consult your owner’s manual and follow the manufacturer’s recommendations to ensure optimal performance and protection for your engine.

How to Do An Oil Change

  • The first thing we recommend doing is to ensure that your vehicle is on a leveled surface
  • Once you have ensured that it is leveled you can go ahead and remove the oil cap
  • Before removing the oil cap you have to make sure there is a drain pan underneath the vehicle to drain the old oil into
  • It’s now time to locate and remove the oil drain bolt. You can do this by simply using a 19mm or 1/4 box end wrench, whichever you prefer
  • Once you have successfully drained the old engine oil, you can reinstall the oil drain bolt
  • We also think it would be a good idea to remove the old oil filter and install a new filter while making sure it is properly lubricated
  • You can go ahead and use your preferred oil and reinstall the cap once you’re finished
  • Now it’s time to start the engine and measure the oil level after 10-15 minutes
  • You can also add more oil if needed
