But as every petrol car I’ve owned has cost much more in maintinece and fuel no thanks ill stick with my diesel
You’re probably going to find that the market won’t agree with you when you factor in future depreciation levels especially in an anti diesel legislative environment.
While are you comparing like with like in terms of engine size/type ( stress ),mileage and age.If so,with the exception of the ignition side of the engine management system,what goes/can possibly go wrong with petrols that doesn’t/can’t possibly go wrong with diesels ?.Bearing in mind the large scale dodgy industry in DPF removal because of the unreliability and massive costs of replacement,for just one example.While even if diesels are supposedly more durable ( doubtful ) the combination of potential future punitive taxation and resulting depreciation will make that as pointless as the marginal fuel consumption advantages.Bearing in mind that even the fuel consumption comparison only starts to make much difference at relatively higher mileages than the 10-12,000 per year average.

More bike lanes, more traffic holdups and then blame vehicles for the exhaust build up. And where will the parking areas be on the motorways, for people to get on the services charging points, that’s also if the electrical suppliers don’t have a power cut through over use. The electric company’s must think Christmas will be all year long.

Looking at the performance and economy figures of some of the new petrol engines like fords ecoboost and the vw/audi tfsi engines the diesel car engine seems pretty obsolete.
For as long as they stay intact they offer good figures.

Not aware of them been particularly unreliable many of the modern tdi engines with emissions systems and variable geometry turbochargers don’t seem especially reliable
That 1 litre Ford lump is getting itself a reputation to rival that of VW’s eforts for reliability, standing by their product about the same too, nil points.
I agree with you about so many modern Diesels, wouldn’t touch one with a barge pole, have no intention of owning any car made after about 2005, but prepared to go a bit later for petrol Subaru.
The latest electronic tat?, no thanks.
The reason for the higher NOX emissions is the higher temperature of the exhaust gasses.
The reason for these higher temperatures is that the are needed for the catalytic converter to work.
Catalytic converters where placed to “clean” the diesels,it smells all a bit and not to diesel, but more to another money making scheme.
To run a heavy good vehicle on CNG or LPG you are struggling with getting enough torque.
Petrol on LPG is nearly as good as petrol on its own, but the mayor problem is that there is no network.
The dual fuel cars of Vauxhall never made big numbers.
My closest LPG filling station is 43 miles and it is in a little backyard of a small taxi company, never get a lorry in there.
Also the weight of the installation has to much negative points.
If I have to pay to drive in any of the big cities, it’s easy, I won’t.
I don’t pay to drive in London, and never will do, my customer can collect it at the border of the M25.

Anything producing much more than 100 lb/ft and 100 hp per litre is obviously going to be on the margins of durability whether diesel or petrol.While to be fair it’s easier to build the strength and cooling capacity required in a larger capacity engine than a small one.Which in this case generally usually means the unfair comparison of 2.0 litre diesels with 1.0 petrol for example.
While the ecoboost predictably seems to look more attractive in the more sensible 1.6-2.0 litre range.

We know that petrol engines in the form of the eco boost for example can produce as much if not more specific torque as diesels and the higher octane level of LPG allows more compression/boost than petrol can withstand.

And as I’ve said before, if we all move to LPG, where’s it all going to come from?
Oil refining only resulting in about 3% becoming LPG, and the burden already on our gas reserves would see the prices rocket if we transferred all our transport to it.
We have already built the infra structure for petrol and diesel propulsion,how green will it be to dismantle this and start all over again with the new flavour of the month.How long until the Government decide to tax LPG or electric vehicles.

As soon as lpg vehicles start to overtake the number of internal combustion engines probably.
All the “health warnings” about e-cigs from doctors and medical “experts” is the government starting the campaign to begin taxing e-cigs in the future as more people begin to use them than cigaretes. No way are they going to lose out on all that revenue and itll be the same with lpg and electric cars

Unfortunately I’ve just bought a newer diesel. Car last week seeing how I normally go a good distance and can usually hit the one mother in law on 3/4 of a tank of fuel. Where as the petrols I’ve had were a a tank and a half so ill be sticking with diesel

If LPG is supposedly in lower supply than diesel how do you account for its massively lower ‘pre tax’ market price v diesel ?.
Meanwhile the real world appraisal of its production and future usage in engines v diesel.

The issue isn’t that the government will always try to rip off anyone who wants to use road transport in whatever form as that’s given until the electorate decides otherwise and stops them.It’s all about the fact that they will hit diesel users ‘more’ than others arguably with good reason.While diesel users are obviously unnecessarily just giving the government more of an excuse to hit us all in that regard.All based on them acting like luddites in wanting to stay with a relatively dirty expensive fuel when the technology already exists to move away from it with no real significant downsides,at least in the form of petrol or LPG fuelled engines.
As for LPG fuelled vehicles they are still internal combustion engines.To the point of being the same as the diesel engines used now but just with a spark ignition conversion and lower compression ratio.

The question is exactly what type of petrol engine v diesel comparison are you going by in that example ?.IE even at worse exactly which comparable petrol engine supposedly has double the fuel consumption of the equivalent size diesel. 
While the figures won’t look so good if,more like when,the government decides that if persuasion doesn’t work they’ll just tax the things until even the most die hard diesel users will have to take notice.
I used to have diesel cars from early 80s a V reg Granada,various Toyota Cressida,Carina, then Skoda Felicia 1.9 diesel (the best of the lot fuelwise ave 60mpg) .Then I exchanged it for a new skoda Felicia 2000ish (one o the last before the fabia came in) converted to LPG a good enough car LPG was dirt cheap but remember the MPG was well down and local wise had a couple of dealers but on holiday you needed to plan the refueling stops out big time. After a couple o years the price of LPG started to rise and I worked it out that it was not working out fuelwise/costwise,so back to Diesel traded in on a Fabia saloon diesel 1.9 non turbo not quite the fuel millage as the Felicia 1.9 ave about high 50ish mpg never had it long enough to run it long as I left for Canada . So as a long time buy diesel all the way for me ,always went non turbo tried LPG good idea but once people jumped on it the fuel price and loss of boot space (tank fitted where spare wheel was) made it in my eyes not worth it. (always bought diesels at around 2/3 yrs old apart from the skodas they were new.) Now getting 14mpg in Canada .
