Is Shell fuel really that much better than supermarket fuel?

I've always used Shell V Plus diesel in my Range Rover TDV8, with 160,000 miles on it. My neighbour said it was a waste of money, so I switched to Asda diesel. My car now has worse fuel economy and runs rougher. Is it just my imagination or is Shell V Plus really that much better than supermarket fuel?

Don't listen to your neighbour. This is precisely why I recommend Super and specifically Shell V-Power. Get back into it and there's a chance it will clean up your engine's fuel system as it used to do. This comes from more than 20 years experience in more than 1000 cars, plus 1,000,000 reader's letters and emails.
