I am driving my E34 m20b20 to and flow KL-Kuantan, re-fuel for RM60.00 when my petrol warning light is on. My maximum speed is 120km/h, i keep maintaining my fuel consumption at 10liter/100km or below it on the highway and didn't high rev when in Kuantan town.On the way back i put in another RM40.00 petrol. Total mileage is 587KM (when i on the way0 to my office my petrol warning light is on again)Just want to know any1 test this before???
