Wazz72 Posted July 6, 2007 Share Posted July 6, 2007 Can anyone tell me any reasons why my supra is slurping petrol like nobodys business. Not to bad on long runs I do about 20 miles a day 5 days a week and its costing around 50 - 60 quid a week. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted July 6, 2007 Share Posted July 6, 2007 Do you drive an NA or TT? Any modifications? Have you got a heavy right foot? Has the fuel consumption recently gone up, or has it always been bad? It could be a worn-out O2 sensor. They cause over-fuelling when they're knackered (AFAIK). There might be a way to test them, but I can't remember what it is. You'd need to search for that. Quote Link to comment Share on other sites More sharing options...
Eve Posted July 6, 2007 Share Posted July 6, 2007 Can anyone tell me any reasons why my supra is slurping petrol like nobodys business. Not to bad on long runs I do about 20 miles a day 5 days a week and its costing around 50 - 60 quid a week. That seems a little high but I am afraid these are thirsty machines! I get around 230 miles out of a tank of v-power driving to and from work through traffic (but get a bit of dual carriageway to blast the turbos), get 280 on a longer journey.

stevie_b Posted July 6, 2007 Share Posted July 6, 2007 Right, that's 100 miles costing £55. Assume a petrol price of 96.9 pence/litre (can't be far off), and bish bash bosh you're getting 8mpg (!) That's quite low. :o Quote Link to comment Share on other sites More sharing options...

Thats harsh, i do the same mileage a week and a full tank would last me about 2 and a half weeks! Quote Link to comment Share on other sites More sharing options...
Wazz72 Posted July 6, 2007 Author Share Posted July 6, 2007 Its a TT, and no im not towing anything, theres no hole in the bottom of the tank, and the handbreak is off when I drive...

Commonest reason for poor fuel economy is a duff O2 sensor. If yours hasn't been changed for a while (eg. 30K miles), fitting a new O2 sensor should have a big effect on fuel economy and smoothness of your engine.
