Bro the engine is the least of your worries, the engine is normally the most robust part of the car... just use any good oil and follow proper maintenance is ok already.
It's the other parts connected to the engine which most likely kaput first.

To me the cooling system is more important than the engine oil..  engine can run even if oil leaking... but coolant leaking, bye-bye engine.

My cars are 13 years and 8 years old respectively, no worries on the engine.. other parts hard to say, see luck.

Hahaha well I have owned and maintained various cars for more than 30 years and all this while none of my cars have complained. My current 10 year old car still returns FC as per the spec sheet reaching over 700km/tank, still able to accelerate 0-100 in around 7 secs and reach top speed in excess of 240kph, engine metal all still in shiny pristine clean condition and sounds smooth like butter.

I pity you for wasting your money unwisely! 

Brather, give chance lah =D

If you need to own a bungalow to know how to tidy up and upkeep a bungalow,
i think most maids would be out of business dy loh;

But then again maids are everywhere...
according to your logic maybe all of them do own multi million bungalows and apartments... ...
