Some of these vehicles have an oil life indicator system that illuminates the light or sends the message on the instrument panel when the oil is due for a change, depending on factors that show when the oil is 'used up'-with the system permitting more than 3000miles between changes, though fresh changes are encouraged for the engine's health. Should one choose to go with the synthetic oil life calculator, absolute maximum should not exceed 10,000 miles. This includes, for example, the necessity of constant oil change because the older the oil is the more it can cause the wear of the engine. It may be useful to gather all requirements tools before commencing and to have rags on hand for accidents. Jacking up the vehicle makes it easy to access the oil screw; this is located at the oil filter. Find the oil drain plug and filter, being careful of the hot parts of the car's exhaust system. Bring the engine to a preheated state in order to enable the oil to drain and then jack up the car in the right manner. Place a drain pan beneath the drain plug, hang it properly and then remove it slowly and cautiously; this should be done to note whether the old oil is containing the metal particles or not. After washing, make sure you clean the drain plug and the surrounding area to avoid having the threads rust and then screw it back and lock it tight . Place the drain pan below the oil filter, unbolt and unscrew the previous filter and clean the mounting area. Alway, replace the O-ring seal and the filter during installation and make sure that it is adequately seated without excess force. Take out tools used in gaining access to the underside of the car, and lower the car then pour fresh oil through the filler cap and check the level. Now, if you are in the pre-operation stage, start the engine and in addition check if there is any fluid leakage and check for the current oil level and add if required. To turn off the Change Engine Oil light put "Oil Life Reset" and hold the enter button. Watch out for a clutch leak and oil level during the initial journeys after the change. Get rid of the old oil in the correct manner, the used oil should be in a proper container with the help of a recycling center.
