What happens if you put off changing your oil for too long? We’ve all been there; it can’t be that bad, can it? You become overburdened with work demands, family responsibilities, and a blizzard of small errands as life gets in the way. You come across that reminder sticker on your windshield one day as you’re sitting in rush-hour traffic.

Why Is Oil Important?

Fuel is converted into power through combustion in your car’s engine. In order to complete this task as effectively as possible, the various parts, like the pistons, cooperate. The lubrication provided by oil minimizes wear and tear by reducing friction brought on by driving. Additionally, it aids in maintaining a stable engine temperature and avoiding overheating.

As the oil circulates through the engine over time, it gathers debris and begins to break down, which prevents the parts from operating smoothly, increases friction, and slows down the engine. The old oil must be replaced with fresh oil in order for the engine to continue operating correctly.

What Happens If You Don’t Change Your Oil

Wear of components

Many moving components, including pistons and valves, are found in an engine. By lowering friction, the lubricating qualities of your engine oil help to safeguard these components. After the suggested oil change interval, the engine oil will degrade and become less effective at shielding the components from friction, which will cause wear and damage.

Over-heated engine

The engine cannot be kept cool with just your coolant system. Due to its ability to reach areas where coolant cannot, engine oil also plays a crucial part in this. Because of the exposure to high temperatures, engine oil deteriorates and thickens over time. This thermal breakdown of the oil prevents it from absorbing heat, which might otherwise cause the engine to overheat, gaskets to blow, and parts to wear out and warp.

Dirt buildup

Engine oil not only cools and lubricates, it also cleans the engine’s interior. It clears away debris and tiny particles. This dirt can accumulate over time and cause the oil channels to become clogged. As a result, the engine’s lifespan may be significantly shortened. Additionally, the engine will have to work harder as a result of the dirt buildup, which will decrease power. Oil will start to gel or solidify in an engine after a long period of time without being changed, eventually becoming sludge. As a result, the crankshafts, bearings, camshafts, and other parts of the valve train will become oil-starved. The engine might sustain severe damage as a result and need to be replaced.

Increased fuel consumption

The engine will have to work harder as the sludge-like thickened and aged engine oil becomes. This implies that to generate the same amount of power, you need more fuel. This increase in fuel usage may alter things by 1% to 2%. In addition, burning old engine oil in your car could emit toxic smoke into the atmosphere.

Voided car warranty

If you follow the manufacturer’s recommendations for maintenance, your car will be covered by warranty. The warranty will expire if it is not serviced properly. If your engine is damaged, you may incur high costs that the manufacturer won’t cover.

When compared to fixing a damaged engine, changing your oil and replacing your oil filter is much less expensive. Your car will operate at its peak efficiency and have a longer lifespan if you use high-quality engine oil and replace it at the suggested intervals. Engine oil is the most crucial fluid your car requires after fuel, so be sure to pick the right kind.

How Often To Change The Car Oil?

Your car’s oil should typically be changed every 3,000 to 5,000 miles. The amount of time it takes to change the oil can vary depending on the type of oil, the car’s model, and how often it is used.

The oil comes in two main categories: synthetic and conventional. Chemical substances mimic the characteristics of conventional oil to produce synthetic oil, but without the impurities. From crude oil, conventional oil is produced.

Despite costing more than regular oil, synthetic oil is made to function more effectively and last longer. People who live in cold climates or travel short distances can also benefit from it because it can warm up and remove contaminants more quickly.

The manufacturer of your vehicle determines the precise type and weight of oil, but most modern vehicles either use a full synthetic or a synthetic blend. For information on the proper oil for your car, consult the owner’s manual. Additionally, you can get recommendations from the auto shop you visit.

Avoid using synthetic oil if your manual suggests using conventional oil; you’ll only waste money because your car isn’t built to use synthetic oil to its full potential.

The frequency of oil changes is frequently determined by the number of miles driven in older vehicles. (The operating manual for your car will list the suggested mileage.) The schedule is divided into two categories: “normal” service and “severe” service. Follow the severe service schedule if you find yourself driving:

  • For primarily short trips (usually 5 miles or fewer)
  • In extremely hot, cold or dusty conditions
  • With sustained stop-and-go movement
  • With heavy loads or for towing

More miles, sometimes up to 10,000, can pass between oil changes on newer cars. Most newer vehicles have oil-monitoring systems that record the number of miles since the last oil change as well as how taxing the trips have been. While some systems are only based on time and mileage, more recent models can also detect when the oil starts to deteriorate.

When it’s time for an oil change, you’ll see a light pup on your dashboard, indicating that you need to bring your car in as soon as possible. Engine knocking, an oily cabin, or smoke coming from the exhaust pipe are some additional indicators.

A Voided Vehicle Warranty

The peace of mind that comes with a warranty is one of the best benefits of purchasing a new car. However, failing to have your car serviced in accordance with manufacturer guidelines could void the warranty.

At Firestone Complete Auto Care, our oil technicians will make sure that your car is serviced with manufacturer-approved oil, keeping it running smoothly and maintaining its warranty. In the event that you ever need to show proof at the dealership, we keep thorough records of all of your maintenance history.

Poor Engine Performance

Oil not only provides lubrication but also keeps the engine of your car clean. The fuel filter, which is changed when the oil is changed, is contaminated by detergents, dispersants, and other additives. All of this grime is forced to circulate back through the engine once your filter clogs.

Smooth, spotless oil gradually turns into sludge. The moving parts of your engine have to struggle through this sludge, making it work harder. The power and torque of your car could be reduced. Additionally, your engine will consume more gas the harder it has to work. That implies that you might be spending more of your hard-earned money at the pump.

Complete Engine Failure

If you neglect your oil change for a prolonged period of time, your car may eventually suffer. Motor oil stops removing heat from the engine when it turns to sludge. The engine could overheat and blow a gasket or seize.

You will be forced to the side of the road by the milky white exhaust of a blown head gasket. Depending on your car’s age and value, fixing a blown head gasket can be a pricey repair that may not be necessary. You might find yourself battling the hassle of the sales and finance staff at the dealership.

Your engine’s parts will warp if the heat does not cause a gasket to blow. Metal will be grinding against metal as the oil’s lubricating properties are neutralized. The engine will stall out. This cannot be fixed. It’s not difficult to imagine how expensive it would be to replace an engine that has seized. Once more, a repair like that could put you perilously close to having to buy a new car.

All of these issues—voided warranties, subpar performance, reduced fuel efficiency, and seized engines—are much more time- and money-intensive than scheduling an oil change at Firestone Complete Auto Care. Our technicians use the Pennzoil Platinum line of motor oils, giving your car cleaner pistons, better fuel efficiency and horsepower, unmatched wear protection, and exceptional extreme temperature performance.


Is it acceptable to go a year without having your oil changed?

The number of miles driven, not the number of years or months, determines when to change the oil in a car. Regardless of how much you’ve driven your car, the majority of manufacturers do advise two oil changes per year.

What indications point to the need for an oil change?

The answer includes things like increased engine noise, increased fuel use, uneven oil texture, and declining oil level, which are all signs of an immediate oil change.
