not total waste my dear. I can feel the difference in terms of power delivery and engine smoothness. Just that wallet says otherwise.
Alot of that so called 'difference' is actually psychological. You may see some minor difference but no where worth the price ure paying for Ron 97 currently. The slightly better mileage (if any) will be easily obscured by the much higher cost of the Ron 97 fuel. Please be reminded that Ron 97 is not like the previous Shell V Power Racing. Although it sounds similar but the RON 97 currently used by Shell for instance is a slightly inferior version.
Using a higher octane fuel will not make much difference to internal carbon formation. Its actually a waste to use high octane fuel when your car only needs a lower grade. You wont get much difference in mileage or engine performance. The truth is that every grade of fuel has cleaning agents. Too much cleaning agents, some say, can actually damage your car.
Octane is a measure of how much the fuel can be compressed before it spontaneously ignites. Only engines with higher compression ratios take advantage of higher octane gas.

yes, no doubt the car can use ron95 but for optimum performance ron97 is recommended. i'm pretty sure there's difference in between.
Recommended by who? The people who run petrol stations in Malaysia? The people working for certain 'agencies' in Malaysia who would love to make more money from gullible Malaysians?
Do some reading up of your own. There are ample resources on the internet. Dont just have the herd mentality.

What petrol does K5 use?
The K5 together with many other cars like BMW, Merc and Audi runs on Ron 95 as its recommended fuel. Many modern cars can even run on Ron 91. Many modern cars have low compression ratios thus enabling the use of low octane fuels. Its only high performance cars with high performance ratios which require higher octane fuel.
