Particulate filter on petrol engine should be maintenance free.

It is also less expansive than diesel ones and works better due the high temperature difference of the exhaust flow...

the bad side is it that filter creates additional back pressure and petrol engines hate that.

the lubricant will also be important and specific

all of this sounds exciting, doesn't it? angry
