No, you can not. The car was not designed for petrol. If you happen to put this in your tank or a gas station adds petrol to your diesel motor it can destroy your engine. If petrol gas has been put in your car by mistake, you'll need to immediately get your engine serviced. This is a very expensive job and will require the garage to drain your tank, put in all new filters, and flush out the engine before you can drive your car again. If you happen to drive the car with petrol in the engine the car will almost immediate stop and not run at all. You can basically destroy your engine if you add the wrong gas and try to drive the car.
