I think most of you relate lube turning black = no good. After speaking to quite a few actually working in the lube industry, it is almost ascertain....BLACK got NOTHING to do with lube good or not.
If your engine got soot and contaminants, a good lube will be able to suspend those contaminant in the oil itself. Thus if your engine is a bit dirty, your oil will turn brownish black even at 2-3K mileage.
Its one of the KEY FUNCTION of a good lube to suspend those contaminant in the oil. It had no affect whatsover on the addictives and lubrication function. However when the oil START to turn honey like. Thats the symptom, its at the end of life of the lube where the contaminant is either too much or the addictives to keep the contaminant from forming sludge worn out. We should avoid honeylike oil from forming thus usually 5K mileage oil change is recommended to prevent this from happening. When it happen, some sludge might have been formed, a bit late.
So if your lube start turning black even at 2K, its might means the detergent function is doing its job and the oil is holding those contaminant in suspend...don't worry if using good lube, the addictive will keep the dirt apart from forming sludge.
Not so sure if its fake, if engine lose power or oil turn honeylike after 2-3K, then better check if not engine issue, change the lube out fast if suspect its fake.
Heard even petronas also got fake (not sure) as sometimes even spare part shops also can't differentiate thus unless you got a reliable source, you might not want to risk it. Thats why some buy from petrol station although more expensive. Peace of mind....sure no fake if buy from Petronas station for example. Hypermarket like Tesco also should not have fake coz they will be in trouble if they sell fake even unintentionally.
Thats the problem, how to identify the originnal lube and fake one ....event the supermarket like tesco and carefour they also unable to prevetn the fake oil cost the dealer who only kena lega action at the end, do you think the foreign contry own supermarket will easyl get in the legal case because the engine oil are fake.

Tak ada lar...too expensive. Mobil 1 CAN last more than 10k, so does a few FS but the claim usually had some hidden cavaet. A true group 4 FS like redline was designed to last over 15k to 25K.....also with cavaet.
In the end, all lubes no matter what manufacturer use this term "We suggest you follow your owner’s manual recommendation".
One of the common critical cavaet is IT CAN LAST depending on engine make (really depends on what car you drive coz different engine make got different cooling system, lubrication function, etc), driving, weather, road, dust, humidity and traffic conditions.
Due to our Malaysian "severe" driving category and our so-call small and mid-size sedan engine design, I would not recommend 10K mileage. At most by 7K to 8K, should change. Personally I gonna change FS at 5K to 6K max to keep my engine performance at optimum condition (change before lube addictives even started to wear out). Yes, its more costly but if you cannot afford to change at 5K mileage for FS or semi, can always switch to mineral...engine will be even cleaner than using FS 10K change in the end.

thats why i suggest using Tesco brand mineral oil ..... and change every 5k km
