Oil change is a regular maintenance, but I can still learn something from it.
I know little about the car. However when I have my own car, I need to know more about it. For example, I need to know how to check the level of engineer oil, especially when the indicator shows "Low Oil Level". Last month, I had this issue, I bought one quart of AMSOIL 5W40, which was the same oil I used from the latest oil change. Then I poured 2/3 of the bottle and the issue was resolved.
Before I went to Appleton, WI, I checked the oil level was ok. But when I drove back from Appleton, the issue came back. This issue made me quite frustrated. I need to decide (1) Top off the oil by buying one quart of AMSOIL 5W40 again, costing around $10, (2) Totally change the oil, and may use another brand, cost more than $100.
I firstly chose the option 1. But the store that sells that oil was closed on Sunday. In addition, my friend T suggest me to use Mobil 1 and totally change the oil. Therefore, I tried option 2. I bought three large bottles of Mobil 1 oils, totally 15 quarts. The oils are cheaper in large quantity, and costs less than 6 $/qt.
Another day, I have an appointment with auto store. They helped me to replace the oil. This oil change used 7.7 quarts oil, so I returned one bottle and kept some oils in case I need to top off. It looked that the issue should be resolved.
Well....Let's see...
Another thing, I learned: There is Always Someone You Can Learn From.
