How ironic, i was just about to post the same question.

I also drive a 1993 3.5v8i with the 89ltr tank.
I get the same mileage of 350km per tank (nearing empty) or roughly 4km per liter for city traffic and 6-7km per liter for hwy.

Quite horrific those figures, but i know the engine is running rich.

heres a link i found on the search tool that might be worth looking into:

RRC 3.5 EFI running rich

best of luck,
jonno

change all the oils to full synthetic including differentials and swivel balls (i mixed half grease and half synthetic oil ) .new distributor cap (Lucas)and wires , plus the conventional things air and fuel filters airing up to spec your tires .

Don't over oil your pod filter or it will fowl your airflow meter and it will go rich, they are a waste of time and only keep rocks out of your engine not dust. First thing I would check with high fuel use is the Vac advance diaphram.

Look, quoting how many dollars in a certain distance or 3/4 tank (from the fuel gauge) is meaningless to us.

Fill the tank, drive around, refill the tank and then tell us how many litres/100km you used. Then we'll know how you compare with us.

Check your timing... Makes a huge difference on economy when you get your timing spot on or if you want to really make a difference take it in for a Dyno Tune.. doesnt get more precise than that and the savings in fuel would possibly pay for it
