Fuel Savings? Seems like a good idea!

Might just be me but am always sceptical of claims like this especially when they say up to 40% accident reduction??
 
Doesnt really explain what it does. I presume watching the video you try and keep the lights in the green or something?

Anyway stuff that right now. Ive been praying for six weeks for the scooter and car to need fuel so we could get a trip out to our only remote petrol station that has a pay at pump thingy. A 30 mile round trip and a lovely day out. :)

I think it encourages a light right foot which requires driving a little slower as well as fuel savings which I guess should help a bit reducing crunches....
 
40 odd years ago I fitted a Vacuum Gauge to my car which did the same thing as that digital gizmo but with an analogue gauge with red and green zones. It worked off the pressure differential in the air inlet manifold.

I can say that it will give you better mpg if you don't drive like a tosser .... so. it's a yes from me.

I would say this is the key - keep in a "green" zone (which anyone with a Rev counter could do by ensuring they keep the engine revs between upper and lower limits) and you will get similar results wihout spending a couple of hundred on a dashtop gadget.
I do this in my van by keeping the revs in the green marked section on the tacho :)

We had a 1750 Austin Maxi with a vacuum gauge and it was really economical for its day. We came home from Aucterarder to Walney once with the car loaded with bikes on the back and a canoe on the roof and it gave us 37mpg cruising at 70mph. Still have a very light right foot, probably the link to my back pocket that does it.

I think with most vans running at about 2000 revs works quite well.

I have a fault code OBD reader from ebay which cost me under £20 which when I use in conjuction with the 'Torque' app on my phone it gives me real time readouts of Accel, Throttle and Boost amongst others which will achieve what lightfoot is doing but with a saving of over £200
 
Most cars have a read out that shows you your average MPG, MPG for a trip or total MPG etc. Just set it so it shows you what your using so when you hoof it you see it go down to 10mpg or something and it puts you off driving like a hooligan. It definitely works as my last Golf had one and I would get annoyed if it dropped below 50mpg. I got around this by buying the stupidest car I ever had. A Hyundai i10. It has no such feature so now I just dont worry about and can drive like a Hooligan again. 😬
 
My Suzi has a live fuel consumption 'gauge' just like this device, with a set of led bar lights, it doesn't tell me anything different than I know anyway, which is, put your foot down hard and the fuel consumption suffers, lift off and you use less fuel. It occasional catches my eye, but I'd rather be looking out observing the road than staring at this.

Totally agree,use the rev counter,it's what it is for. Keep in the right rev zone,accelerate gently except when overtaking,avoid braking at last minute,that's all there is to it.
 
Most diesel engines are most efficient when on their rev band of maximum torque. Look up what revs your engine gives maximum torque and try to keep the revs around there. The biggest danger with "cockpit fixation" is looking at the rev counter / vacuum gauge / gizmo and running into the back of something... After a while you can get a feel for when the engine is feeling happy, a happy engine is an efficient engine.
 
Yes driving in the torque band is best for a diesel, but in my car i go out for a burn up which is 3.5 to 4.8 in the rev counter eating the road up as a race driver which gives me a buzz, if i wanted to toddle i would get the boring bus. ;)

But if you are a poor driver, you will get that £230 back in fuel savings. :giggle:

What I will say is that by having some form of guidance on driving efficiently, it teaches you better driving habits which you instinctively use for the rest of your life.

The only reason I fitted a vacuum gauge many years ago was because I removed the dashboard top from a Mark 2 Cortina GT in a scrapyard and fitted it to my 1600 cc Cortina. The vacuum gauge was to replace one of the original gauges that was no good to me. I was travelling over 60 miles a day to work and back and realised that I was wasting fuel by being a boy racer. :) That was nearly 50 years ago and I still drive to conserve fuel ... except when I slept in for work. :giggle:
