Before we start the topic, answer the following questions:

  2. How often do you do the service?
  3. How do you drive your car?

Maintenance is the key to keep your car running smooth, reduce future repair costs, and optimizing your car’s performance.


Oil change, how important it is? Open your browser, search “what happens if you don’t change oil”, and click image(I apologize I don’t want to post those pictures on here). Engine oil is the essential part to keep your engine running smooth, lubricating the parts inside the engine while it working. Fail to change oil, inside of the engine starts to get sticky and gummed up and it is hard to flush out, you can still drive it until it stops working and/or burned. In the worst case, you will need to replace a new engine, and maybe other parts have different level of damage as well, which can cost you a lot of money to fix it. Remember to change oil filter at the same time, it helps to filter out the dirts to ensure your engine won't get sticky with dirts, which is really important. Here is an video from Youtube, chanel EricTheCarGuy, in his case is not too bad, at least you won't puke when watching. Check it out, have better idea on oil change.


Spark plug, don’t ignore it, you car can't start without it, and it is directly linked to engine performance. If you are experiencing the following cases, maybe it is a signal to change spark plug

  1. Engine idles roughly.

  2. Having trouble to start your car in the morning/ can't start.

  3. Engine misfiring.

  4. Engine surging and hesitation.

  5. High fuel consumption.

  6. Reduce performance.

bad condition parts can lead engine work imporperly. Changing it based on your car, matterial made of your spark plug. Here is the video from Youtube, about how to replace spark plugs, inspect spark plugs, gap spark plugs,  figure out what spark plugs are best for your car and where to use antiseize and dielectric grease. What I would suggest for the spark plug is, get it from manufacturer, it is best fit for your engine.


Fuel filter, what does it do? It filters out the dirt from fuel so only clean gasoline enter engine, like any filter, keep it in a good shape to help the engine stay clean. If dirts enter the fuel injector, it can clog and damage fuel injector, which can lead engine does not work properly. Gasoline quality is one of the factors, I am not saying everyone should get the highest grade of gasoline, but the quality of gasoline grade is vary by companies.


PCVvalve, a bad PCV valve can cause Engine idles roughly, engine light on, engine oil leak, sludge, high fuel consumption, lack of acceleration. Change it when necessary.


Cooling system, throttle body, air filter, transmission fluid.
