VW Engineers Added Diesel to Motor Oil in Gas Engines to Cheat on CO2 Emissions



What? The VW cheating story keeps getting worse every week. New information came to light recently. VW engineers confessed that they also cheated on carbon dioxide emissions in up to 800,000 gasoline powered cars. That’s right. This is in addition to the “dieselgate” with the complicated software that defeated the test procedure.

This time, the engineers turned to physical modifications for cheating. The VW management demanded low CO2 numbers, and when the engineers could not achieve the numbers – they raised air pressure in the tires and added diesel to the motor oil in the gas engines to burn less fuel and run cleaner. It’s not immediately clear about how diesel oil additive works to reduce fuel usage in the test vehicles.

Low CO2 emissions numbers are especially important in Europe where taxes are dependent on these numbers. VW stated that it will correct the problem by paying the tax different and/or fee for the affected customers. The cost of this additional scandal stands at $2.2 billion.

The engineers confessed this to management in late October of 2015. This cheating began in 2013 and lasted until the spring of 2015. How deep does the rabbit hole go? We already know that the “dieselgate” scandal was expanded to the 3.0-liter TDI engined in Volkswagen, Audi, and Porsche vehicles. We will have to wait and see how the story develops from here.

Here is the TFLcar investigation of the “dieselgate”.
