I've got over 150,000 miles on my car, I've never had any issues with the fuel system, and I've never used an additive in the fuel system. All the fuel system components on the car are original.
That said, I had an E60 in which the methanol ate the seals in the secondary (i.e. high-pressure) fuel pump but I haven't encountered any problems with any other of my cars.
Am I just lucky?
