V Vectra 1996 Fuel Consumption - wymthg
I have a 96 1.8 LS Vectra and o a trip down the dual carridge way my fuel consumption seemed to half, I went about 90miles and used more than half a tank of fuel.

What could be causing this?

I know from a friendly (ex) Vauxhall service manager that some of the early ones suffered from a 'sticking' fuel gauge. Not sure what was causing it - the sender, display elecronics, or the gauge itself as my previous Vectra (96 2.0) didn't have this problem.

The problem is caused by wiring obstructing the operation of the sender unit making it show half instead of full. The cure is to re-route the wiring so that it clears the unit. A VX dealer should know all about it as the problem is listed on the VX Tech info system.

Sorry I may have not explained the problem correctly.

The fuel consumption is halved as in I only get so many miles to the gallon, I am burning more fuel than I should be.

The fuel gauge is fine.
