I know it's been asked a few times before but just want some advice from people who might have an idea what they're talking about.
My 1997 1.6 16v escort has 98,000 miles on the clock, i've recently changed the oxygen sensor as the old one was bent and knackered causing some strange idling problems and crap mpg.
Since changing it my fuel economy seems a bit better but it's hard to tell as the day i changed it was the day the supermarkets knocked their petrol prices right down. Before i changed the sensor i was getting about 65 miles out of £10 of petrol, i'm now getting around 80
- 85 miles out of the same amount of petrol which i make to be around
29 - 30mpg. Is that about right or should i be expecting more?
I expected slightly more. I work with someone who lives just down the road and he drives a 2.5l V8 ford probe does a similar amount of miles but uses about the same amount of petrol i do.
Also, my car seems quite smoky a lot of the time, especially when cold but a lot of the time it does it when the engine is warm and has been running for a while.
What should i be looking for to eek those extra few mpg out of this car, i'm fairly handy with a spanner and a haynes manual so any suggestions are welsome.
