My modern is a Skoda diesel, the first diesel in a long time and boy have they improved. In February I got the particle warning light on, had to look up what it meant! At the time we were on our 3 week thermal cure and the car was only being used for very short runs at low speed. The first trip to the supermarket gave me the chance to give it a bit of a blast to heat it up, nice trail of smoke to start with 😱 but soon cleared. The ad Blue gets topped up once a year just before we go on hols.
Demonised? OH YES.
Just after buying it diesels were declared enemy N°1.
Then the government declared they want to get rid of heating by oil, guess what we use.
Followed a week or two ago by some bright spark wanting to up the tax on "SUVs" because they pollute, my Skoda is a Yeti so an SUV I guess.
Triple demonised, I'll just keep my head down til it all blows over. . .
