Oil change interval
Something as simple as finding an optimum schedule for changing your engine oil actually turns out not to be so easy to decide. Although some manufacturers advice to change the oil every 10,000 miles or even less frequently, you may want to have it replaced much more often, depending on individual circumstance. It all depends on how often you drive your car, on what distances and under what external conditions.
For instance, if you are driving only on short distances, mostly in the city being stuck in traffic jams, your car may rarely get hot enough to evaporate the water that forms in the crankcase and builds up sludge in the engine. If you suspect that your engine may be exposed to extremely harmful conditions, you may need to change the oil even every 3,000 miles. But if you want to find the optimum frequency, seek professional advice. This way you will ensure to make a decision that is safe to your car, as well as affordable and does not require too much of your precious time.
