it actually depends on where u stay.... i stay in pasir ris, where there is no discounts, but as i often go serangoon gardens, i pump my petrol there.... 6%.... not bad if u are thinking abt the long run.... and abt which company, it all depends on wat kinda petrol u wanna pump, if its normal 98, then i think you should choose those that is easily available, and that u know the existance in various parts of singapore, just in case u run out of petrol at places u seldom go.....
just my 2cents worth....
