What will happen if I change my engine oil very often?
Changing your engine oil more often than recommended does not cause any engine problems. In certain situations, your vehicle may demand an oil change before the recommended interval. It may be the case if you drive long distances at a time (20m per trip) or if your vehicle is overused in extremely cold weather.
If you decide to change your engine oil without any external issues (as highlighted above), there will also be no adverse effect on your engine. You can even decide to change the oil every week if you like. However, this would have no tangible influence on your car. There is a reason automakers recommend you hit at least 3000 miles before you change engine oil. If anything, changing your engine oil too frequently may be considered a waste of time and result.
Can needing an oil change cause reduced engine power?
Yes, it can! Although it isn’t the only cause of reduced engine power, having low or contaminated oil can result in a lack of acceleration. An engine with a low oil level would see its performance diminish due to its inability to lubricate its parts properly. Failure to change engine oil on time would affect engine power through; Reduced output, Increased fuel consumption, Severe overheating, etc. In some cases, the vehicle may go into limp mode due to sensor reading problems in the engine.
To resolve this issue, you must drain the old oil and replace it with a new one. You can also take the vehicle to a mechanic shop for further inspection.
Is it normal to hear a ticking sound from the engine after an oil change?
Even after refilling your engine with new oil, there are instances where a ticking sound may come from your engine. For instance, where the new oil applied is of inferior quality, its subsequent ineffectiveness in the engine may cause this ticking sound. Here, the cheap oil cannot adequately lubricate the engine components.
Also, if a wrong oil filter is attached to the engine, it will fail to properly remove contaminants from the engine oil. These contaminants would accumulate over time to form sludge deposits which can seriously damage your engine.
Oil leakage due to a loosened oil plug is another problem that can cause ticking sounds from your engine. To be safe, you can delegate engine oil changes to a qualified technician.
