It's been called unleaded ever since the lead content became illegal and was removed. Lead replacement additives are available for cars designed to run on leaded petrol and have soft valve seats which would be eroded by unleaded fuel. Leaded fuel was withdrawn in 2000. Unleaded was introduced in 1988. Last edited by: Old Navy on Mon 1 Feb 16 at 12:15 Reply to this message | Report message

Thanks. Because we don't have emissions control here, there's a lot of old vehicles which still run on LRP, which has some other anti-knock agent in it. Reply to this message | Report message

Anybody who thinks you have to be an idiot to put the wrong stuff in is wrong. I'm sure there are one or two on here who have gone quiet after making such a comment! To this day I don't understand why I did it and remain convinced I had put petrol in my can. However, when I filled up the three wheeler at home, the contents of the can were diesel fuel. As a bit of time elapsed between the filling and trying to start - it wouldn't and I missed the fact the starter was misaligned and ended up wrecking the plate (part of the external flywheel). Cost me £80 for a new one and roughly half a day of my labour to pull the engine, swap the bits, drain the tank and put it all back together. In case anyone wonders, 'why the can' the local petrol station can be a bit of a bun fight and working out the quantities and dosing with two additives is best done at home.

Unless you're in the habit of pouring inadvertent orange juice on your cornflakes! The pumps are clearly marked, what's so hard? We have a diesel and a petrol car, it's really not difficult to remember which one takes which type of fuel. I publicly declare that if I ever even come close to doing such a stupid thing, I will admit it and if I were to actually get as far as to squeeze the wrong pump trigger I will not only admit it but dance naked with a petrol station flower in my teeth round Nelson's column. ;-)) Reply to this message | Report message

I've put fresh orange on my corn flakes as well. I've also made a cup of instant coffee in a cup which already had a teabag in it...not nice at all. I fuel up both our cars, petrol and derv. I put 30 quids worth of super unleaded on top of 30 quids worth of derv one day...I blame the pump having a black handle. I got home ok..only 300 yards at most and spent the afternoon draining it down. We were using the car for a trip to Appleby the following day..hence the fill up. Ruddy hard to get it out, too much gubbins under the bonnet. I got the back end up as high as I could and wriggled a 10mm fuel pipe in the filler until I could get resistance blowing through it. It was too short to make a vacuum so I found a length of copper central heating pipe and added that at the sucky end. It did get most of it out and I went and filled up again. Expensive mistake !

Petrol in a diesel is possible when you get distracted or have something on your mind so the refuelling is on autopilot.

You make it sound like multitasking is impossible. Surely everyone does it all the time? How many people doing any or all of those things actually do hit something? And how many people hit something who aren't doing any of those things? I accept that the more things you are doing at once, the risk of distraction becomes higher but I think many people are smarter than you give them credit for and would be quite capable 95% of the time carrying out a phone call while driving without increased risk. The dangerous people are those who aren't good drivers and cannot anticipate or who normally drive with aggression. Reply to this message | Report message

Yeah - unless you are saying they were on the phone, I think that supports my point. Which was that you don't need to be on the phone to have an accident, and many people would be able to be on the phone without having one. I am not advocating phone use while driving but it isn't the most dangerous thing out there, in my opinion. However it is one of those things which we can readily see and therefore label the drivers as idiots. Reply to this message | Report message       1

Also there are a lot of unlicenced drivers or foreigin drivers who have little experience of driving in high density traffic and have little or no knowledge of our driving laws and rules.

Lead was a lubricant for the valve seats as well as raise the octane level and prevent knocking, but I recall when unleaded fuel was first launched that certain petrol engines were damaged/ruined as a result (Vauxhall?)
