[Closed] Fuelsure filler caps!

I am paranoid that i am going to put petrol in after years of petrol cars!

Then you are unlikely to do it! Do you fill up without thinking about it?

Mol no but id i was tired rushed + I have a wife too! 😉

If it's a newer car it'll probably have the narrow still filler anyway.

are you female?

Stoner nope but as i said I do have a wife.......

dont let her drive. Simples.

That fact that you're paranoid about it will stop you putting the wrong fuel in. I've always had petrol cars and bought a diesel 6 tears ago, I still have the fear which is a good thing. Funnily enough when I put fuel in the pterol car I never think that way.

Gary I know, I have never done it but we just say automatically , must stop for petrol!! am i subliminally telling myself to put petrol in?

Stoner but then I cant drink!
Unless I make sure car is always full

Stoner but then I cant drink!

Good point. The downside of my misogyny! 😉

Start telling yourself that you are stopping to fill the car with diesel and make a point of identifying the diesel pump when you pull up.

As for the wife- point out what a shame it would be if she had to sell her shoe/handbag collection in order to put right any damage done by mis-fuelling.

You say stop for petrol - but then you pull into the station and look for a suitable pump. These days you have to check which fuel you want, since they are all equally available. To pick petrol, you have to actively search out the green one (and get ultimate/v-power/equillium/normal) even if you have a petrol. Given all that choosing, it's hard to accidentally get petrol when you want diesel. My point is that it's not an automatic thing, so I never get it wrong.

I'm with mol, there's 3-4 fuels available at every stop, how can it be automatic?

That said, I've known several people who've done it.

It's not at all uncommon.. I find this surprising 🙂

Although I must fess up - with my first car I put about 5l of diesel in it when it was petrol. No idea why that happened. I'd never owned a diesel, my family had never owned one..

Just ordered one of these since there is always the possibility of anyone doing a mis-fueling by accident (we have a petrol and diesel)the potential bills for stratospheric. For £30 it seems to be a no-brainer.

£30 for your own peace of mind isn't bad, but don't think I'd buy one. As Drac said, your car almost certainly has the narrow filler that will not allow a petrol nozzle to fit.

Underhill - diesel nozzle is bigger so will not fit in a petrol, but the other way round will fit - petrol in diesel.

Oh. Yeah that sounds probably right.

*gets coat*

I have read that you need to make sure that the nozzle is totally empty, when you twist the cap as diesel coated shoes aren't a good look!

Nor are petrol coated shoes! 🙂

Presumably because adding a it of petrol to the diesel tank is ok (they used to add a small amount of petrol to stop diesel from freezing in cold weather) whereas diesel in a petrol engine is a big no-no

we did this to death a few weeks back but in summary, modern diesel cars have very fine tolerance high pressure pumps that actually use the diesel to lubricate themselves. Petrol is a solvent and washes the lubricant away, and therefore can damage these pumps seriously, costing top $ to replace. A bit of petrol would be OK, but a tankful could screw the pumps up before you've even driven it, as the act of unlocking the car can prime the pumps in some models. Drive it, and you could risk the whole engine.

Diesel in petrol is not good but in general the car will just run rough and eventually stall. Drain and refill and you might be luckier, as eventually the petrol will dilute and disperse the greasy diesel. You might need new fuel filters, etc. but less likely to be a major problem.
