7/22/2018 stopped at bp gas station to fill up with diesel, at the side pumps were full so we were going around the pumps and seen the green handle on the pumps pulled in and filled up, and truck quit on us about 5 miles down the road. Now we are pulling a 33' 5th wheel camper behind us. Flat stuck, broke down at 2 p, m, and didn't get home till 12:30 p.m.. We have come to realize by other customers that this is not the first time this has happened with BP. Do you people know that this error is some major dollars to customers to fix a diesel engine. BP / unleaded petrol coming through diesel pump. you know that if all the pump handles were red it would be different, but you have 3 red and 1 green on each pump, that is soooo stupid. I will tell everyone I know about this and the fact you and your company feel like they need not comply with the way the american people identify gas and diesel at the pumps, I will never buy from you people again, I dont care how good you are. One mishap like this is one to many.
