That goes to show how cheap engine oil can be.
If the manufacturer of Carlube can sell it for a profit, plus the middle man, NTUC Fairprice making a profit as well, and there's also shipping costs all the way from UK, and yet a profit can be achieved by selling 5 litres of fully synthetic oil at $29.
Doesn't it feel silly to be paying $110+ for 4 litres of Mobil 1 or Shell Helix Ultra?
honestly, since you've already paid so much for the car, whats $110 more? you may argue you have to save money since you've blown so much on the ride, but thinking back, hey.. just take bus!
$110+ for some uncles and matured drivers is peace of mind. similarly, ask some people to install tires such as firenza and sonar or whatsoever, they would refuse and rather pay a premium for bridgestone, toyo and whatsoever. why?
they trust the r n d. so honestly, no point feeling dumb about it. to each his own. use whatever works for you, but try not to offend better who are better off and do not mind spending more just for the peace of mind.
