There is a petrol partculate filter coming soon - in fact some manufacturers such as VAG are already fitting them to production petrol engines with Mercedes and "many more" opting to follow soon.

And with several, credible worldwide sources declaring that some modern petrols are worse than much older pre-DPF diesels for emitting high levels of exactly the same damaging particulates, I reckon its only a matter of time before their fitment becomes mandatory to all engines. So, I suspect that the balance in relation to the cost of maintaining the emissions control equipment will be the same in the future, regardless of what fuel your car uses.

In addition, if the method of regeneration of petrol particulate filters is the same as their diesel counterparts, then several years in the future its going to be very difficult to find a car which is suited to short journeys.

For those pushing the Petrol over Diesel advice, also take a read of this

There are several other sources, all saying exactly the same thing. Petrols can be just as damaging as diesels as far as those particulates are concerned, even more so when the other noxious substances they emit are taken into consideration.

So why drive a diesel and poison the Country with damaging particulates, when you can drive a petrol and kill off the same people with three nasty emissions, including Benzoapyrene, which is carcinogenic. Isn't petrol just as much of a problem?.

I wonder how long it will be before "petrolgate" begins?, same tax, same city bans and a whole exciting new witch hunt. Eventually those diesel owners swapping for petrol will face the exactly same issues and city taxes as they are worried about now, as the circle continues, which is why I keep an open mind in relation to the crusade to move motorists away from diesels.
