Product Description

Putting petrol in your diesel vehicle can be an expensive error. At best, you need to have the fuel system drained. At worst, serious damage can be caused to the engine potentially costing hundreds or even thousands of pounds The AA estimates that about 120,000 motorists a year fill their vehicle with the wrong fuel. Think! Diesel is a simple but clever sealed voice unit which is activated by light when you open your filler cap. A clear, urgent voice reminds you ""Stop! Diesel, Remember! Diesel" twice. The unit requires no wiring - simply fix to the inside of your filler flap with the sticky pad supplied. It is activated by light when you open the filler flap. The bright yellow box acts as an additional reminder. Particularly useful if you regularly drive both petrol and diesel cars - maybe you have one of each in the family - where a moment's absent mindedness could have catastrophic consequences Suitable for diesel vehicles with an opening flap over the filler nozzle. The unit measures approximately 32mm x 72mm x 10mm deep - please check there is space under your filler cap (very few don't have space). Integral battery is not replaceable as EU safety laws require the unit to be sealed. However, the battery should enable the unit to be activated around 600 times Available in bulk at a great price for retailers!

This simple device has a self adhesive pad. I stuck this inside the Diesel Fuel Filler Cap Flap. Make sure the fixing position is clean, before fixing.

Once the flap is opened & the Photocell is exposed to a light source a programmed voice says quite loudly: 'Remember Diesel'

It repeats this twice more, a total of three times. It is a simple device which is thin & still allows the Fuel Flap to be closed.

Costs under £5 which includes the postal cost. There are other devices which are fastened around the filling spout by Grub Screws. Thes are getting towards the £40 mark.

I can thouroiughly reccommend this Product.

Cheap and effective. Much cheaper than buying a new motor or even paying 20 Euros to have your fuel tank drained if you are lucky enough to remember you have a diesel car before starting up (speaking from experience).

Note - in the winter months if you fill up at a dark petrol station the light sensor in this may not trigger. I thought my one didn't work until recently. Luckily the sight of a large yellow object on your fuel cap is also a help.

The voice is annoying. It is meant to be.

This won't fit on some cars. It was a challenge to fit it into my C4 Grand Picasso. They do show you the dimensions so go have a look how much space you have.

In the US diesel cars are pretty rare and fueling stations often only have one or two diesel pumps; very easy to zone out, pull up and grab the wrong one. Hopefully this will be enough to keep us from zoning out. It does exactly what it says, it's simple and loud. It fits easily inside the filler door on my VW Jetta Sportwagen (that's a Golf Variant in UK I believe).

Brilliant device. My wife has put petrol twice in my diesel car, it's an easy mistake to make, but an expensive one. This device sticks to the inside of the fuel flap and gives a nice loud siren and diesel warning, activated by light, every time the fuel cap is opened. My wife says it makes her giggle every time she fills the car up!!

I have been thinking of inventing this device for a long time and when I saw it for just one pound ..yes one pound !! I had to buy it ..sometimes my wife [who drives a petrol } has on a few occasions nearly put petrol in my diesel .its not just a gimmick its an excellent device and so affordable .just stick it to your filler cap and everytime you open the cap a clear warning tell you ;;warning diesel.. you would have to be a massive plonker to misfuel with this bit of kit .I am sure in the near future all diesel cars with come with some warning device as standard .again a must for any diesel car owner fantastic device ,fits the hyundai Tucson no problem I have just found a problems with this device ..its disposable !! mine was getting quieter and I thought that I could change the batteries but you carnt ..I know they are a cheap device but I hate to through things away .so I bought another one ?? I got my first one from Halfords for one pound !!..

the think diesel device is a little "belter".It speaks clearly and reminds you twice that you must put diesel in your car. I put additional screening around the sensor, as it was occasionally going off if strong sun shone on that side of the car.I received the item by return of post.

I run a fleet of cars and despite a sticker on the dash, one on the outside of the fuel flap and one on the inside, people still manage to put petrol into our diesel cars! Since installing these, we've only had one misfuel.

OK so it's a little bit embarrassing with it 'bing-bongs' and stern sounding gent warning you to put diesel in but if it saves you a whacking great bill then it's job done. The only thing I would say is that in isolation, they are loud enough but on a noisy petrol station forecourt they can be hard to hear. As i said, we still had one misfuel despite the warning being in place.

They stick well on the inside of the flat - none have fallen off so far. They are light activated and seem to work well at night, even under dimmer forecourt lighting.

Having been caught out putting petrol into my first diesel car, I decided to put some warning device in place!.....IA voice warns you to ensure DIESEL is used.
I have founds this device works ok... but have noticed on the odd occasion it fails to sound when the fuel cover is opened.
I can only put this down to not enough light exposure to it when the cover is opened.
But for the price, I think it is really good value! Especially when I was quoted £200 to drain the petrol out!!
