Scheduling an oil change is one of the most important steps you can take toward protecting your vehicle, and it’s especially impactful in the hot months of summer. The summer heat can significantly affect the efficiency and longevity of your vehicle’s oil, which can have long-term impacts on the health of your vehicle overall.

Reduced Viscosity

One of the primary functions of the oil in your vehicle is to lubricate the essential parts and systems in the engine. This helps to keep them moving properly and prevents damage due to grinding or scraping. Unfortunately, the heat of summer can affect the viscosity of motor oil and cause it to become thinner. This makes it less effective at lubricating parts, leading to an increased risk of engine damage.

Increased Build-Up

In order for the powertrain system to function properly, oil needs to flow through the system. When the hot weather hits, however, it can actually speed up the oxidation process. That means sludge begins to form, which can clog up the hoses and affect engine function. If you find you’re getting more oil clogs, the heat might be to blame.

Higher Evaporation

Everyone knows that liquids evaporate fast in the hot weather. Unfortunately, this can include the oil in your car. If you notice that your oil levels are dropping dramatically, it may be due to the heat, but you always want to check and make sure there’s no leak in the system. In the hot weather, it’s a good idea to check oil levels more often, so you won’t run the risk of damaging the engine.
