Well I think it comes down to what engine oil & rating u're using to last 10k KMs. Zeng & I have both tried various brands of engine oil (semi & fully likewise), and came to conclusion that Castrol Edge & Magnatec provides best engine protection. Even with Magnatec semi, at 7k KMs the oil is still golden in colour, as opposed to Petronas/Shell that turns black rather quickly; within the first 4k KMs from the service.
Turning black quickly, does it means also it cleans out the engine more efficiently (thats some of the theory floating around). Maybe golden means it does not unsludge as effeciently
Lots of opinion outside but there's a quite a number with opinion as below
"I am attached to one of the lubes distributor in MY and, I only recommends max a 7K km "stretch" if you are too busy to change your lubes... And I only recommends FS and SS if you wants your engine to perform better, to be much cleaner and to have better fuel consumption but stick to the regular OCI, that is at 5K km.."
Here's a quote from Volvo:
"Synthetic oils do not allow further extension of oil drain intervals. It is the contamination rate, i.e., soot, and the depletion of additives, rather than base oil quality that determines the useful engine oil life and therefore the oil change intervals."
There is one other opinion
"I would be worried if your oil didn't change colour after driving 5km. The purpose of the engine oil is to lubricate and clean the engine internals. So if after 5k of driving and your oil is still nice and clean - better stop using that oil brand."
......haha ----> Castrol ????
Really getting confuse sometimes...

really? why the salesman didn't tell me about it? he only tell me got 1 year free service..
If you're h-line and just bought your car recently (May onwards, not sure about April)...you're supposed to get the E-Voucher printed directly from dealer. 1K, 5K, 10K and 20K FOC labour and PARTS. Not sure abt ATF change in 20K, not listed maybe have to pay but spark plugs, engine oil, filters should be FOC with this e-Voucher.
AND my darn SA tak da cakap also. DID NOT even mention free service until I found out thru internet and ask him.
