Hi, All! i have a collegue driving a 3yr old Matrix & he uses Carlube. So i just wanna share his feedback with everyone. His driving style is he likes to rev to 3-4k rpm and his annual milage is very high at abt 25,000-30,000km.
According to him, Carlube works perfectly fine for his driving style up to abt 7,000km. Then his engine becomes noisy. So he services his car every 7,000km with Carlube. If he's planning a long road trip up to M'sia, then he'll use Mobil1 for his service, if not, he sticks with Carlube.
He likes Carlube coz it can tahan his harsh driving style and because it's cheap, he can afford to service his car every 7,000km. This is his 2 cents. Hope it helps.
