Standard EU tests are broken & don't represent real world driving shocker!.. oh sorry we've know this for god knows how many yearshttp://www.telegraph.co.uk/motoring...estimate-pollution-pumped-out-by-diesels.html
It pretty much says that in London each diesel car is 3 times over the maximum actually allowed.
"emit around three times more NOx pollution in congested traffic than is permitted in current European emissions tests"
A well maintained diesel engine on average has a more efficient combustion stroke than its petrol equivalent, but the diesel has a lot of nasty additives which after combustion are released into the air as carcinogenic particles < 10 microns. This is dangerous because particulate matter < 10 microns is not commonly produced by nature so we haven't evolved effective ways of filtering it from our lungs. These carcinogens are inhaled deep into the lungs, and particles < 2 microns pass through the lungs into the blood.Seems like whenever I read anything about diesel pollution, much is made of cars polluting the roads. In my experience the cars are pretty clean: clean(er) engine, stop/start mode, etc.
The same applies to petrol cars. The sub-2 micron particulates are as prevalent in petrol if not more so. Euro 6 will require particulate filters for petrol too. Diesel is picked on because of the obvious cloud from older engines. Petrol is not s o blatant, and the technology to measure superfine particulates has been slow to develop.A well maintained diesel engine on average has a more efficient combustion stroke than its petrol equivalent, but the diesel has a lot of nasty additives which after combustion are released into the air as carcinogenic particles < 10 microns.

being a cyclist I don't drive many miles. Once a month I go to Costco and buy 40-60 litres of veg. The Missus feels hugely embarrassed as I stand in Costco car park pouring it into the tank giving a cheery and cheeky wave for the astonished onlookers.Drago, I have this picture of you shoving carrots into the filler cap.
I drive a pickup, does that make me a numbskull?
I'm not intro cars, buy my transport solely for practical attributes. The large front cabin suit me well - I can't drive a focus if the drivers door is closed - and the rear bed is ideal for bicycles or my wife's wheelchair.
I've converted it to run on veg, so the emissions are far cleaner than any diesel with over 3/4 less particulates, and its closer to carbon-neutral than any commercially available car by a huge margin. It also means I can fuel it for 65p/L, so at low 30s to the gallon it costs less than a Nissan Micra to run.
So who's a numbskull?
