Bugger, I must have the most thirstiest non turbo ever made, im getting about 15l/100km, its a r33 auto so its obviously going to have higher consumption than a manual. I've changed the O2 sensor, had it serviced etc. What could be wrong? Apparently there are pin-holes in the exhaust, but i was under the impresion these are after the cat and surely this wont affect much, could the gearbox be slipping? it feels fine however.
Any ideas would be appreciated
Cheers
