is there a recognised convention concerning the colour of inserts for fuel tanks on modern cars? I know this sounds naive but......and I should be grateful for an answer quoting any legislation etc. that may cover this please.

Thanks

Don't follow this - are you wondering about some coloured collar that you can see when you take the filler cap off to fill up? On my diesel Peugeot, when you open the filler flap there is a sticker saying 'Diesel' and when you take off the actual filler cap everything is black plastic. What are these inserts you want to know about, please?

MiNI has a green insert (unleaded) BMW has a black one (Diesel)
Landie's is crud coloured.

Hi TourVanMan,

Simply the answer is no. I do have a tdi but the 'insert' is green and does restrict the insertion of a diesel nozzle. Mauufacturer says the correct tank is fitted. Ho,hum! I may have a Friday Afternoon Hybrid on my hands.

Hi, indeed it is this collar that confuses me. Green on a tdi.

Unleaded filler pumps had a smaller than usual nozzle to fit filler pipes,going back years I know.

But this did help stop putting in fuel car was not meant to run on,I also think this only applied to certain makes..Rover 213 was one that had small filler point,IE a larger nozzle would not enter fuel pipe filler tube,so you knew it was wrong fuel.

Dont recall this being recognised convention though??,unless I have got this wrong again?

Isn't it the case that the unleaded spout is thinner, so whilst you can't put diesel in your petrol car you can put petrol in your diesel? I'm assuming all petrol cars now have a narrower aperture?

We still don't know what the OP meant by 'coloured inserts' so we aren't helping him. 5th Gear had a prog on Saturday re putting petrol in a diesel and vice versa. This showed that it is possible to get a diesel nozzle into an unleaded filler (just) but you have to force it. The effects of misfuelling were shown to be able to be fixed oneself if one drained the tank, filled with the right stuff and drove the car. Didn't even bother the cat but this did NOT apply to common rail diesels - they couldn't afford to sacrifice one for the test!

Thanks to all contributors. Obviously the manufacturer(s) fit whatever thay like and let the poor user make their own mind up!

If you are still unsure whether your car has got incorrect parts fitted then why not nip down to your local dealership and have a look at a few other similar cars and see what they have. If they are the same as yours then its obviously a standard part, if they are different then you may well have a 'friday afternoon' hybrid.
