check ur car properly. make sure got torch light inside the emergency box.
test top speed after 1k km. after u break in then only use 97 la.... ur new car still new... no point to pump 97.... unless u wanna race with friends... hehe...
the difference between ron 95 and 97 not much different. please note u pay 90 sen to rm1.10 extra on premium petrol depending with type u pump in. cannot pump everytime... BMw = Burn my Wallet. for NA cars not much difference. turbo car like my volvo 850 does give big difference.
ron 95: pump at BHP petrol (millage so much better than shell ron 95). city drive 590-650km. highway 750km+++.
ron 97: pump at shell petrol. V-power 97 or racing *ron98/99 (whenever possible, located one in TTDI there) better mileage compared with other ron97. city drive 630-700km. highway dint test as i rev a lot.
tested with all kind of petrol. caltex, petronas, shell, bhp, esso/mobil (same). esso not that bad...
worst ron 95 is caltex and petronas.
ron95 shell still have half tank from subang to singapore border.
ron95 bhp at ss13@ persiaran kewajipan(in front summit usj) is the best bhp. superb service and free mineral water every rm30 of petrol pumped in.
