Shell South Africa
95 unleaded petrol

I went to this particular garage to fill up the car on Monday (02/12/2013) in the evening but upon driving i noticed something, the fuel consumption rate on the car was way too high than normal way. i drive a mazda 3 dynamic and have been driving this car for over a year now i know the expectations on the petrol if i fill it up. i always put in petrol from the same petrol brand and i never experienced this. my suspicions is that they put in 93 although the pump is marked 95. i am very disappointed with the product. sampling on this specific pump needs to be done to see if the density is the same as that of 95
