Is it necessary to change engine oil at a 4S shop?

[Iker]

When changing engine oil, if the vehicle is within the warranty period, it is necessary to go to a 4S shop; if it exceeds the warranty period, there is no need to go to a 4S shop for the oil change. Method for changing engine oil: Place the old oil container under the oil pan at the bottom of the vehicle's engine compartment, use a specialized wrench to unscrew the oil filter and remove it (the location of the oil filter varies by vehicle model); slowly loosen the oil pan drain bolt to release the old oil. After a period of draining, reinstall the drain bolt, but do not overtighten it to prevent damage to the oil pan. Once the oil is fully drained, tighten the bolt (not too tight), then pour the new oil into the engine and screw on the oil filter. After adding the oil, remember to check the oil dipstick. Precautions for changing engine oil: Choose the appropriate oil. Strictly select the oil grade specified in the user manual; drain and inspect; add the correct amount of oil. Do not add too much or too little; recheck after changing the oil. Do not add too much or too little.
