The exhaust does smell a bit wierd, but I haven't had any problems with it in bikes or cars
Most likely you won't have any damage to your vehicle. I would say that your biggest risk would be long term damage to a catalytic convertor, but that is only if you run that stuff on a daily basis. Once in a while shouldn't hurt it, but if you try burning that stuff during a smog test then you may run into a bit of trouble and have to retake the test with a cleaner fuel.
