Removal of DPF filters in new vehicles
I live in South Africa and am concerned about the DPF filter technology.
1.How difficult is it to remove the DPF filter and reprogram the system to eliminate the DPF injection cycle?
2.Should this be achieved would there still be a problem with dilution of crankcase oil running on B100
3.Would there be a problem with the high pressures in new engines on B100?

Should the answer be that the modern engines would run happily on B100 should this be done I would have no qualms in removing this ridiculous system whether illegal or not.The crux of the matter is that running on B100 one wouldn't be contributing to global warming.
In our country we have these popular vehicles Toyota 2.5 and 3litre, Ford 2.2 and 3litre,Nissan Navara and Hardbody 2.5litre,Isuzu 2.5 and 3litre, VW Amarok 2litre.Does anyone know whether all or any of these vehicles would be compatible with B100 should the DPF filters be removed?

1.) Depends on the vehicle and the depth of your pocketbook.
2.) Depends on the vehicle and the delete methodology.
3.) Probably not; both high pressure common rail and VW unit-injector engines have good anecdotal records on biodiesel blends that meet ASTM spec. I once ran a VW Touareg V10TDI on B100 for around 50k miles with nary a fuel-related problem other than a filter change or two. My 2004 model was never equipped with a DPF.

A.) I don't know South African law, but what you propose would be illegal in the U.S. Enforcement here has recently greatly increased on the manufacturer side. I don't know how successful it has been, but programmer and pipe kits were for a while much harder to find than they were a year ago.
B.) The crux of the matter is that global warming is junk science.
C.) We have none of those car/engine combos in the U.S., so I can't help you there.

Think that pretty well covers it.

Speak with Jon Heron about B100 in common rail, he reported a while back he was having good results.

The crux of the matter is that DPF's have nothing to do with greenhouse gasses and global warming.
They help remove the tiny particles present in diesel exhaust that are known carcinogens

Exactly, and if you operate your vehicle in a city using diesel fuel you should have one, or be running biodiesel blends which can significantly reduce the most harmful pollutants for far less cost than DPFs. If you live in cities you're supposed to pick up your dog poop too. You probably can't have an outhouse or a compost pile either, and taking a pee in your backyard will likely get you arrested. That's what happens in totalitarian socialist societies. Laws are made to control the stupid and uncaring elements in a society. Most of it is easy to avoid if you don't live in a big city where the stupid and uncaring elements are the majority.

Talk about a sidetrack... One of the great pleasures of owning and living on a few hundred private acres is relieving myself whenever and wherever I please. Few people would describe my place as living in bucolic squalor; sometimes the big well-plumbed house or shop just isn't nearby when you're fishing on the pond or cutting trees in the woods and feel like watering Mother Nature a bit. If a little poop and pee on the land scare you so badly, what do you do about all the animals out there???

There should be a "like" button on this site as there is in Facebook.

Hey, Im from South Africa aswell (KZN). Nice to see another face from the "wild continent" (hehehe). Anyway, in answer to your questions. I dont have a DPF in my car as it happens (pre 2007), but i am planning to upgrade some time, so ive been watching (and hoping) that a sollution to this appears before i have to buy another vehicle. I did find this though (from somewhere els on this site). Hope it helps and maybe even puts your mind at ease a little.

PS: with regards to South African law: there is not yet any against removing a DPF, our cars do not get tested anualy either, so you are pretty much free to do what you want (for now). We DO have a "emmisions tax" on new vehicles, but the emmision gets teseted at the factory, and the once-off tax is included in the price of the new vehicle, after that, there is no more emmisions tax to be paid, and no tests.

DPFs and the chips are not installed in Central America. Super high sulfur diesel here so the DPF wouldn't function properly. I drive a common rail 2012 Mazda BT50 2.5. Runs great on b100.
