went for a day trip to kepala batas last wednesday with a full tank fillup in KLIA using shell.mine's an m52b28 e39.the drive up was at legal speeds all the way (110km/h set on auto crz)which was where i thank my lucky stars as there were 2 full blown road blocks on the hiway near tapah and after ipoh,on both sides of the hiway!!!however the trip back later in the day was at 160-180,as it was raining sporadically,surely the cops must have retreated into their comfortable balai...the drive back was so nice and smooth that i did not notice the fuel gauge....being on the hiway...the sg buluh overhead r&r was the life saving petrol station that saved me from being stranded due to lack of fuel.....whew.............2 miles to go till empty on the obcerrr...total distance travelled on a full tank was 472.9 miles....
