By topping it up, how much are you actualy putting in? would be a big puddle on the floor if rocker was leaking as much as it sounds like it is
1 Litre per 1000, 1 Litre per 100 miles?
What model/engine and what is your real average mpg folks?
pondering on replacing the volvo with one in 12 months time but being daily and company paying for fuel i need to hit a certain MPG (50), whuch i realise they wont do, but i dont mind putting the odd tank in

$1700 + shipping + import tax + vat + profit
which at a rough guess £1146.59 + £50 + £250 + shipping + dealer profit is gonna put them way up there in the £2000 area, Ap's work out cheaper not sure how comparable they are though.
Used to have crap or none existsant dust seals, d2 seem to get better reviews.
For me though godspeeds offer thats on for 6 pot aps for £1250 would be the route to go if I was upgrading, not as cheap as the d2's but ap's are the muts nuts when it comes to brakes.
