OBD2 ECO Chip Fuel Saver, OBD2 ECO Fuel Chip Tuning Box, Fuel Economy Tuning Box, 15% Fuel Save Plug Drive Chip, Green ABS Ecochip for Petrol Cars, Universal for Cars Since 1996

This is the third one I have bought over the past few years. Although I find they have a life span of about two to three years, during this time, it has paid for itself many times over. Would definitely buy again. For anyone who hasn’t tried one ,give it a go.

So i thought i would buy this give it ago!Ok so no instructions no idea how to use it. I had to go on YouTube to find out not very happy with this product and guess what it didn’t work.Look at the packaging it came in. How cheap does that look it’s like having a green light sitting in the car that does nothing

It takes a while to see the saving on fuel

I was sceptical about it at first, but after 350 miles I've still got over 1/2 a tank. Going round town, I used to get 32mpg at best, I now constantly get between 45 - 62mpg round town

I have fitted this to my daughters car and shall review her fuel usage weekly

Don't waste your money. This doesn't work I seem to be using more petrol than before I put it on. I used to get 23mpg plug this in and I get 18.9mpg absolute rubbish not worth the envelope it came in. Pity you can't put no stars

Did see any improvement at all in mpg

This is a fantastic product - it has increased my car's economy from 45mpg to well over 200 AND doubled the acceleration when I put my foot down. I've also noticed that the scratches and bumps in the bodywork have gradually disappeared with the device plugged in - so no need to spend any more hard earned cash on those body shops. Also, my wife, who has always had difficulty with parallel parking now finds that she can back into any spot with her eyes closed. Seriously! We didn't expect the device to be this good. Though we knew of course that it WOULD work because otherwise Amazon wouldn't allow it to be sold - right?
