Useful thread, going to see how the VTR does.

Useful thread lads. I've just signed up to this website, on a mates advice. I have a question which I'm hoping someone might be able to answer and help solve a problem that's been getting worse the last 3 / 4 months.
Basically, I used to get well over 300 miles per tank with my VTR. Since the engine management system picked up a fault with the exhaust sensor (sorry, can't remember name but I think it's something like the lambeth sensor? - not great with car engines!), and I've had it fixed, I've been noticing problems with fuel economy. Since my car was serviced in September, I've been lucky to get 300 miles from a tank. During the last two months, I'm struggling to get 250 per tank. This has gone from 54 to 39 mpg, which is starting to make a big difference to my petrol bills every month. I just wondered if anyone else has suffered from something similar. I realise certain factors affect the mpg, as mentioned on this thread, but I'm starting to think there is something more serious at fault with the car. Any comments would be appreciated. Cheers.

hey man, lambda sensor was replaced based on what you've said. How is the engine running? performance still ok?

Ah cheers, that's the one. Performance seems to be ok, which is why I'm getting a little worried. I'll probably wait until payday then take it to a local garage. The engine mgmt system light has come on again, so maybe they can pick something up.

Barry123 · 5th January 2009, 20:29

that was what I was going to ask, but I guessed that there wasn't a light or you would've mentioned it in the first post lol

I'd check that lambda sensor once more (connection could be loose)...

actually when the ECU light comes on, the ECU reverts to a 'safe' mode, basically like windows, it runs without sensing from lambda and another one which I can't remember off the top of my head, which means the efficiency drops as a result. It only does this when the ECU suspects a fault with one of the sensors...

Yeah, I forgot to mention that important bit about the ems light! cheers

Also mate, the winter weather hampers fuel economy too.

Lower gear?

Does seem really high though

I was on a website the other day called www.wonderhowto.com and a guy on there doubled his mpg from about 17mpg to about 34. Firstly he did the usual things like tyre pressures and servicing. After that he was getting around 24mpg iirc then he says 'here's the bit the fuel companies don't want you to know' he reckons adding pure acetone (nail varnish remover, must be 100% acetone) gives you a good increase in mpg. He gained an extra 10 mpg from adding something like 2 fluid ounces of acetone to his tank. I haven't tried it because i don't really know anything about acetone and i didn't want it rotting any seals in my engine or any other damage it may or may not do. If anyone wants to try it i'd be interested in the outcome or if anyone can tell me if it's just a load of breeze.

Just joined as I'm thinking about getting a VTR and I saw this thread. What's the best mileage any of you guys have managed out of a VTR? I have a 40 mile commute every day, all on the motorway where I sit at about 60.

Very useful thread

Hi mate welcome, I used to drive 25 miles each way to work and would get and 47mpg in my VTR. You should do well if you stick to 60

(if you can stick to 60 that is)

Nice read
