Shell V-Power Diesel is the best fuel I have run so far. No economy increase so on price alone I run the Shell Fuel Save.
BP Diesel - Engine is silky smooth and quiet, throttle response is just not there.
BP Ultimate Diesel - As above, no noticeable difference felt, won't run it again.
Shell Fuel Save Diesel - Hands down my number one choice due to price, throttle response is noticeable, engine little less silky and smooth as BP fuels.
Shell V-Power - The grin is huge, slight throttle response increase over Fuel Save, when I'm doing long runs I will fill up with it. Engine and my foot love this stuff!
Supermarket - All I hear is injector noise, if I have to use I will put enough to get me from A to B!
