Hi all.

My car is a fiesta mk4 1.25 with close to 100k miles.
I've worked out that my mpg is terrible, maybe half of what it should be, If I fill up right to the top, plus the bit in the pipe, I will get around 200 miles out of it when the tank reaches 1/4 full, so around 250 miles a tank.

I've read people are getting much more than this, what can be causing such high fuel consumption?

Cheers, Jason

 

do u do short trips? cos cold start and short trips drinks fuel ,or maybe lamda sensor knackered i had that on my old escort mk6 1.6

 

i had a mk4 fiesta with a 1.25 zetec in it, was pretty good on juice, around 40mpg just general driving. if it's only short trips then it's always on warmup enrichment and will use plenty more fuel.

 

I get about 250 to a tank in my puma engines Zs. And that's modded and drove hard. Only used to get 200 out had a crapy mk5 1.25 I ran for a little while.

 

I do some short trips, but I also do alot of long trips too.
I think I need to replace my lambda sensor also as its the original.
