Media post: Should You Change Your Oil or Use a Different Oil in Hot Weather? Essential Tips for Summer
When summer hits, the heat can also settle in quickly. And if you’re planning a quick weekend getaway or a cross-country trip, you’ll want to be mindful that your vehicle can also experience strain from rising temperatures. Warm weather is great for beach days, but not so great for your vehicle, particularly your engine oil. Here’s everything you need to know about oil types, when to change your oil, and how to maintain your vehicle all season long.
How Hot Weather Affects Your Engine Oil
High heat in general causes engine oil to thin, which in turn reduces its ability to lubricate and protect vital engine parts. Thinner oil can evaporate more quickly, especially in older engines or under heavy use, leading to increased engine wear and potential overheating. The oil also breaks down faster in extreme heat and with more intense driving. So if you’re driving in hot climates, going on a long road trip, towing an RV or driving in the mountains, this oil degrades even more rapidly.
When to Change Your Oil Before Summer Travel
Longer drives, higher speeds, and heavier loads make it all the more critical that your vehicle has clean, effective oil. Fresh oil ensures your engine stays cooler and runs more efficiently, particularly during long hours on hot pavement. It also helps protect your engine when idling in traffic or running the AC nonstop. Even if you’re not yet due for a change based on mileage or time, it’s smart to change your oil before hitting the road for any extended summer trip. Keeping your vehicle in peak condition can prove favorable with your current insurance provider or when shopping forcar insurance quotes.
Should You Switch to a Different Viscosity for Summer?
Oil viscosity refers to the thickness of the oil and its ability to flow at different temperatures. It’s indicated by numbers like 5W-30 or 10W-40. In summer, some drivers actually switch to a higher viscosity oil (such as 10W-30 instead of 5W-30) to compensate for thinning in hot weather.
If you want to do the same, check your owner’s manual and consult with a mechanic. Most engines are designed to run well with multi-viscosity oils across a wide range of temperatures. However, in some cases, switching to a heavier oil could reduce efficiency or even void warranties. That said, if your vehicle is older, burns oil, or if you frequently drive in extreme conditions, using a slightly thicker oil in summer may provide better protection.
Conventional vs. Synthetic: What’s Better in the Heat?
Synthetic oil handles extreme temperatures better than conventional oil. It resists breaking down under high heat, maintains its viscosity longer, and offers better engine protection. And while it costs more up front, synthetic oil also lasts longer and provides better protection for your engine, saving you money in the long run. Using synthetic oil may even positively impact your car insurance indirectly, by helping to prevent engine failures that can lead to breakdowns or collisions.
How to Check Your Oil Level and Condition
Regular oil checks are a not-so-fun but oh-so-necessary habit, especially during the summer months. Here’s how to do it:
– Park on level ground and turn off the engine. Wait a few minutes to let the oil settle.
– Pull the dipstick, wipe it clean with a cloth (to avoid touching the hot oil/dipstick), reinsert it fully, then pull it out again.
– Check the oil level. It should be between the “min” and “max” lines.
– Examine the oil’s color. Fresh oil is amber and clear; dark or gritty oil may need to be changed.
Signs Your Oil Isn’t Protecting Your Engine Properly
Here are a few red flags that mean it’s time to replace your engine oil:
– Unusual engine noises such as knocking or ticking sounds may mean your oil is too thin or low.
– Your oil warning light could indicate low pressure or serious issues.
– If your car’s engine temperature runs hotter than normal, degraded oil might be the cause.
– Poor oil quality leads to inefficiency when it comes to fuel economy, so if you’re burning more gas than usual, that might be why.
– Exhaust smoke, especially blue smoke, may signal burning oil.
Other Fluids to Check During Summer Maintenance
Oil isn’t the only fluid your engine relies on. Summer heat can affect all vehicle fluids. Don’t forget to check:
– Coolant, which keeps your engine from overheating. Flush and refill if it’s old or contaminated.
– Transmission fluid, which can be broken down by high heat. Regularly check the level and color.
– Brake fluid is crucial for safety, especially when brakes are under strain in hot weather.
– Power steering fluid ensures smooth handling in traffic and tight turns.
– Windshield washer fluid needs to stay topped off to help keep your car on top of bugs, dust and pollen.
Pro Tips for Keeping Your Engine Cool and Running Smoothly
In summertime, your vehicle is your ticket to freedom, whether it’s hitting the road for that dream vacation or running errands around town. Here are a few ways to keep your car in peak shape even when temps skyrocket:
– Stick to a regular maintenance schedule, and don’t wait for warning lights.
– Get hoses and belts inspected. High temperatures can make them crack or snap.
– Check your radiator and fans to keep your cooling system in top shape.
– Avoid idling for too long by turning off the engine if you’re waiting in extreme heat.
– Park in the shade when possible to reduce overall heat stress on your engine and interior.
– Keep an eye on your temperature gauge, and pull over if it starts to rise.
Hot weather puts extra pressure on your car’s engine and its oil. Whether you’re heading out on a summer road trip or just commuting in triple-digit temps, paying attention to your oil type, level, and condition is essential. Switching to a synthetic or higher-viscosity oil may help in some cases, but always check your manufacturer’s recommendations. And don’t neglect other fluids or routine maintenance, especially when they can help keep your engine cool and your auto insurance costs in check.
