Shell Garage on N1 Jhb around Samrand facin Jhb

On the 24th I was supoised ro drive ro Durban on holiday .I poured a full tank of Petrol on N1 Shell Garage facing Jhb.I got on with my travel..After the 1st tollgate the car showed an engine light and list power. Its a Mercedes C200..I saw Vaal Truck stop and got there for safety...The car was towed back to Merc on 14th Avenue Constantia Kloof..They have since discovered tgat the petrol was contaminated , they are waiting for test resilts...The sample i saw looked like petrol was mixed with water as there was a clear substance at the bottom..Holuday messed up...Had no car for the entire festive..Its shocking to see so many people complaining about petrol at Shell ..Such a disgrace
