Haaay... Toyota and Isuzu delivery... with Innovas, Fortuners and Alterras racing at 120-140 km/h up the South Super Highway on their way to Manila. Wonderful way to break in "green" engines, huh?

I can't honestly comment on whether your fuel consumption is bad or not. If your Innova is an automatic and you're driving in Makati-level traffic, it's possibly quite normal. But with the odometer and speedometer non-functional, how can you tell?

Also, the trip-meter and fuel consumption computer isn't completely accurate, as it gauges transient fuel consumption. Press all the way down on the gas and it'll go way down. Coast to a stop and it'll hit 20 km/l. The only accurate way to tell is to calculate gas usage from tank to tank, with knowledge of the actual distance travelled.

I've never heard of disconnected odometers on Toyotas before... on Hyundais, sometimes, but not often.
