does anyone else find that asda and tesco petrol gets sucked through faster than a more expensive petrol?
Yes. Morrisons fuel I find is the worst.
I always put £50's worth of fuel in my car each week. It doesn't matter what the price is per litre I just put £50 in.
I find that £50's worth of Shell or BP premium diesel will get me about 400-425 miles. I put £50's worth of supermarket fuel (this gets me more in volume as the price per litre is less) and I will be lucky to see 390 miles from it.
When I kept using Morrisons I was barely getting 360 miles for £50's worth of fuel. The price of fuel has dropped a little bit but not enough to make 50 miles difference. Its just s***e quality fuel.
