I hope this is still useful

I just noticed as of today this post has 295 views. I suppose I should have posted this years ago, but I seem to have the time now.

It seems my timing is all off. As of this post, we are in a worldwide pandemic so people are hardly driving. Russia and OPEC are in a price war. Oil futures traded at less than zero dollars per barrel. Gasoline was being sold outside Denver for $.99/gallon while diesel was still $2.20/gallon. Tighter emissions regulations and Dieselgate have essentially killed off the small diesel in the US. There is not much incentive to buy a diesel now in the US. We don't get the Greenline versions that are available in Europe and gasoline engine cars are getting much better mileage with direct injection, CVT and multispeed transmissions. Electric cars are becoming more widespread.

Perhaps those of us who are fans of the diesel get it and will be able to keep our cars for a long time and enjoy the driving experience while getting great mpg in these cars.
60 mpg hwy highest, 50+mpg lifetime
TDi=fast frugal fun
