I put £50 in my nearly dry 4x4 on Saturday , normally it would register half full on the gauge but only made it up to quarter on this occasion , sure enough 80 miles later I need more fuel so not a faulty gauge as far as I can tell, Ive got my receipt and debit card slip from the garage and remember the pump number . This happened to anyone one else? what did you do ? Next stop trading standards? Is it possible to fiddle the readings ? I`m pretty sure it would be possible for a techie.
