If engine oil levels do not require topping up, avoid restarting the engine as damage may occur. A red dashboard oil light can mean one of several things, such as: Your oil level is low. The engine could burning the oil, leaking oil or both, if the dipstick indicates a low oil level (you don’t see an oil on dipstick or level of oil below or at ADD line). Another cause of low oil pressure can be a failing oil pump or a blockage in the system. Prolonged oil pressure loss can often result in severe engine damage. BUT, engines are engines, physics is physics. Excessive clearance results in low oil pressure. Two reasons for your oil light to flicker. If the oil light illuminates while you’re driving, you should immediately pull over and turn off the vehicle. If your car isn’t leaking oil, the low engine oil could be due to the oil getting burned away by the engine’s normal functioning, since it generates a high amount of heat. The oil pressure in your car plays a huge role in lubricating certain areas like the camshaft and the shaft bearings, which then in turn reduce the wear of these parts and prevents overheating. Earn some money by selling your car and put that towards a brand new vehicle! Oil is picked up by the displacement of an oil pump and forced through passageways into bearings, such as the main bearings and big end bearings. However, oil filters in cars tend to get clogged after a long time of use, especially if they are not checked and replaced during the routine oil change. More specifically, a low oil level will cause the oil pressure inside the engine to temporarily drop. You have to understand that the light indicates the oil pressure, not the oil level.If this happens, it’s bad for several reasons. If anything were to damage or puncture the oil pipe, then it could start leaking oil at engine pressure – which is highly dangerous. This is needed in order to maintain a proper oil level to prevent further damage. Oil is in charge of lubricating the engine of your car so that the parts move freely and are not obstructed. This typically indicates an issue with the gauge, like a leak, or that a part of the engine has worn down and created a drop in the oil pressure. Labor costs add onto that total cost, coming in between $900-$1148, and parts are an additional $260-$348. From there, the oil flows through various passageways inside of the crankshaft. Oil leaks are a common cause of low low oil level in the engine, and can originate from various places. If you have topped up the engine oil, restart the engine to check if the oil light goes out.
