Hi

on a 1.8 8v mk2 (RV) engine what MPg should I be getting ?. I've rebuld the 8v engine. it's done almost 1000k since the rebuild.
I'm sure my timing/tuning needs to be corrected. but can any one advise what MPG I should be averaging ?

according the the MGF when the car is cold I get 27-32mpg but once at normal operating temp, the mpg goes down to about 16mpg. any thoughts ?

your advice is appreciated.
