"When should I change it?" This is a common question, and the answer varies significantly depending on the age of the vehicle.

In the past, the saying "Change it every 3,000 miles!" was widely accepted, but this is not applicable to modern cars.

Vehicles made before 2010 had simpler engine designs, generated more heat, and the oil would get dirty quickly, so changing it every 3,000 to 5,000 miles was appropriate.

At that time, the use of conventional or semi-synthetic oils necessitated more frequent changes.

In contrast, vehicles made after 2010 have much better engine technology and typically use synthetic oil, allowing for changes every 7,500 to 10,000 miles.

Some models can even go beyond 10,000 miles without issues.

Hybrid and luxury brand vehicles often have longer recommended intervals.

The problem lies in Texas weather. Here, just parking outside in the summer can heat up the engine significantly.

In such hot regions, engine oil deteriorates quickly, and the strain on the engine increases. Additionally, with traffic jams and air conditioning running at full blast, the oil wears out faster.

Therefore, in hot areas, it is advantageous to use products that are resistant to high temperatures, such as 5W-30 or 10W-30, which provide good stability in summer. However, a higher number does not always mean better, so it is safest to choose the viscosity recommended in the car manual.

Modern cars have sensors that check oil condition and provide warnings like "It's time to change the oil," so you can trust and follow that signal. However, for those who frequently drive short distances, like home to work, it is advisable to change the oil every 6 months to a year based on 'time' rather than mileage.

In fact, car maintenance practices have changed completely over the years. Older cars required frequent spark plug changes, coolant top-ups, and regular timing belt replacements. You had to keep a close eye on them to ensure longevity.

However, modern cars can last up to 100,000 miles on spark plugs, and with the shift from timing belts to timing chains, replacements are rarely necessary. Coolants are also long-lasting.

With cars now providing maintenance alerts, it has become acceptable to check in only when prompted.

Still, one thing you must remember is: "If you frequently use the air conditioning in hot and congested conditions, you need to change the oil more often." This rule still holds true.

After a summer season, checking the oil condition at least once can greatly help your car last longer.

Finally, even if you're busy, make sure to occasionally check for any oil leaks under the engine.

A small habit can make your car more comfortable and trouble-free for several more years.
