An oil change is a crucial auto maintenance job. While you can call an expert to change your engine oil, doing it yourself will save you money and help you understand how your automobile works. The procedure is pretty straightforward, but it’s best to be cautious and learn what it takes to perform an oil change successfully. Before listing the common oil change mistakes, let’s understand why changing car oil is essential. Why are car oil changes necessary? Engine oil circulates through the engine to keep its components lubricated. This lubrication helps the parts move smoothly and reduce friction as the car runs. Without oil, the higher friction between the engine’s components would quickly reduce mileage and performance, affecting the life of the automobile. However, the oil’s ability to reduce heat and friction reduces with time. It usually becomes darker in color and thicker, indicating it’s time for an oil change. Common mistakes when replacing car oil Here are a few mistakes to avoid if you’re changing your car’s engine oil by yourself without assistance from oil change services: Not using a drain pan A drain pan is a container into which used engine oil is drained. It helps avoid messy spills on your garage floor and allows you to transport the oil to recycling centers.

Multiple myeloma (MM) is a kind of cancer that forms in the plasma cells, a type of white blood cell. Plasma cells allow one to fight against infections by producing antibodies that attack any foreign substance entering the body. Multiple myeloma happens when cancerous plasma cells outnumber healthy blood cells in the body. Keep reading to learn about the warning signs of multiple myeloma to remember for an early diagnosis and timely treatment. Causes When a person has cancer, plasma cells accumulate in the bone marrow and outnumber healthy blood cells. Instead of producing normal antibodies, these cancerous cells make abnormal proteins, which cause several health complications. In multiple myeloma cases, the body might or might not show symptoms. Since the disease often does not cause symptoms until it reaches an advanced stage, an early diagnosis is difficult. Sometimes, it gets accidentally detected during a routine blood test by showing an abnormal protein level. Signs and symptoms of multiple myeloma Some early warning signs and symptoms of multiple myeloma are listed below. Symptoms Nausea – When cancerous plasma cells cause bone damage, bones break down, and calcium enters the bloodstream. Excessive calcium levels can trigger nausea. Bone pain, mainly in the chest and spine, is a common symptom of MM, triggered by bone damage due to the myeloma cell growth in the bone marrow.
