very high petrol usage please advise
I get 15 miles/gallon. Car is a selespeed 156 2.0ts. The lambda sensor doesn't work and can't be fixed , electrical problem. Thermostat is working. It doesn't matter at all if I drive like an old granny or an F1 driver I tried both shifting at 2200 rpm and very slow acceleration for a tankfull and another with very hard acceleration redlining it almost every shift with no difference in economy. Also start stop driving and highway driving makes no difference in economy. I can't smell any raw fuel and there is only a very very slight smoke oil/petrol when I rev to the limiter in neutral. Engine is in good condition and new spark plugs just put in. Please help I don't know what else to do
