Does Summer Driving Increase Oil Change Frequency? | Newhub Auto Repair

Summer is here, and with it comes road trips, weekend getaways, and more time behind the wheel. But all that extra driving, especially in the scorching heat, might have you wondering: does summer driving increase the frequency with which you need to change your oil? The answer, like many things in automotive maintenance, is a nuanced “it depends.” Let’s dive into the factors at play and help you determine if your summer driving habits warrant a change in your oil change schedule.

The Summer Heat is On: How Temperature Affects Your Engine Oil

Your engine oil’s primary job is to lubricate the moving parts of your engine, reducing friction and preventing wear. But oil also helps to dissipate heat. In the summer, ambient temperatures rise significantly, putting extra stress on your engine. Here’s how:

• Increased Engine Load: Hotter temperatures mean your engine works harder to maintain optimal operating temperature, especially with the air conditioning blasting.
• Oil Thinning: Extreme heat can cause your engine oil to thin out, reducing its ability to properly lubricate and protect engine components. This can lead to increased wear and tear over time.
• Oxidation: High temperatures accelerate the oxidation process of your oil, causing it to break down more quickly and lose its protective qualities.

Stop-and-Go Traffic: A Summer Driving Killer

Summer often brings increased traffic congestion, especially in tourist destinations and major cities. Stop-and-go driving puts a strain on your engine oil in several ways:

• Extended Idle Time: While idling, your engine is still running and generating heat, but you’re not covering any distance. This can lead to excessive heat buildup and oil degradation.
• Frequent Accelerations and Decelerations: Constantly speeding up and slowing down puts extra stress on your engine and its oil.
• Reduced Airflow: Slow speeds reduce airflow around the engine, making it harder to dissipate heat.

Towing and Heavy Loads: Taxing Your Oil Even Further

Planning a summer vacation and towing a boat, camper, or trailer? Or perhaps you are hauling heavy items often? Towing and hauling significantly increase the load on your engine, which translates to increased heat and stress on your oil.

• Higher Engine Temperatures: Towing puts a heavier demand on the engine, leading to higher operating temperatures.
• Increased Oil Consumption: Engines working harder can sometimes burn more oil.

So, Should You Shorten Your Oil Change Interval?

Based on the factors above, here’s a general guideline. Consider shortening your oil change interval if:

• You frequently drive in extremely hot weather (above 90°F).
• You spend a significant amount of time in stop-and-go traffic.
• You regularly tow heavy loads.
• Your vehicle manufacturer recommends shorter intervals for severe driving conditions (check your owner’s manual).

If none of these factors apply to your driving habits, you can likely stick to your manufacturer’s recommended oil change interval. However, it’s always a good idea to check your oil level and condition regularly, especially during the summer months.

Newhub’s Recommendation: When in Doubt, Check It Out!

The best way to determine if you need a more frequent oil change is to regularly check your oil level and condition. If the oil appears dark, gritty, or smells burnt, it’s time for a change. Furthermore, consider a professional inspection. At Newhub Auto Repair, we can assess your oil and provide personalized recommendations based on your driving habits and vehicle.
