Hmmnn... base on what Schwepps provided, our engine can only last 100k miles because we are using 5w-30 oil provided and recommended by SC. That means 160k km..

Averaging 30k km per year, we should be selling our ride immediately after it crosses 5th year.
For turbology's car, he's using 5w-40 so his engine can last 150 miles, that's 240k km. So he is in no hurry to sell his car until approaching 8th year..
Of course that 8 years on the road, you will be passed by similar cars that runs on 5w-30 which is slightly more powerful and more economical..
If u run 10w-50, that's 320k km.. or 10w-60, that's 400k km.. that's why I ask why u stop at 240k km..
For me, I had to stop at 5w-30 unless I wish to sell my car after 100k km..

Unless I make enough for upgrade every 3 years..

....... unlikely..
