fuel consumption

[ozonehostile]

all depends on your driving when it comes to fuel consumption. if your doing short journeys, i.e. less than 15 miles, the consumption will be high as the engine will only just be warmed up as you get to your destination, i get about 120 miles for my £20 doing the commute to work of 12 miles. motorway driving and your mpg should shoot up.
primer grenade and leak off pipes are a good thing to check for fuel leaks anyway, also the filler neck into the tank is known to leak on 306's
