Every internal combustion engine’s lifeblood is the oil you put in it. This oil must be replaced at regular service intervals. You’d be surprised at how many people just drive their cars without giving a second thought to basic auto maintenance tasks like this. Everyone who drives a car should know what goes on during an oil change, and the horrible, super-expensive scenarios that result when you don't follow this simple maintenance routine. Here are five examples of what happens when you don't change your oil. Remember: spending on basic maintenance is better than shelling out a huge sum of money for a major repair, after all. 

Heavy goop. As the oil ages and loses its anti-wear properties, it can form into a thick sludge. When this happens, the muck can block the oil passages and lead to oil starvation between the moving parts of the engine. This is very bad. How can you tell if oil isn’t changed? Pop open the valve cover. If it is caked in a black, tar-like substance, you know you’ve got a problem.

Accelerated wear. Oil catches the microscopic metals that flake off due to natural engine wear, and you know that the oil is doing its job if it changes to a darker color. However, if you don't change the oil, it becomes saturated with contaminants that the filter can’t separate. Again, this results in dramatic wear of the piston rings, cylinder wall, and camshafts because the oil turns abrasive when left unchanged. This will eventually lead to serious engine damage.

Overheating. One of the primary functions of oil is to keep the engine cool. To do so, the oil has to flow freely through all of the tiny passages and between the piston rings, cylinder walls, crankshafts and camshafts. If it is thick and heavy, this flow is impeded, leading to an engine overheat that can be catastrophic.

Fuel mileage will suffer. When an engine is no longer operating within the proper parameters, it won't do its job efficiently. Once there is damage because of neglecting oil changes, it will chug more fuel because combustion will be inefficient. 

Overhaul—perhaps even replace—the engine. In the worst-case scenario, the oil has become abrasive and no longer flows properly through the passages and between moving parts. This will result in damaged pistons, cylinder walls, crankshafts and camshafts, and the main bearings. The engine will overheat, and the cyclinder head and engine block will most likely be damaged. This will cost a huge amount to repair. You may be better off buying a new engine.

The main defense against a mucky, ill-performing engine, is periodic maintenance. Make sure that your lubricants are always fresh: don't neglect this simple, yet very important, tip.
