Especially when you both get my train of thought right away.
Yes, you are correct Skip. More pollution for better economy of fuel.
And Yes, if you do run regular Diesel Fuel (500pps stuff) in the econo-diesels (costing an extra $3K) it will ruin them to the point of becoming "regular" diesels.
But, how does that ring with the environmentalists, more pollution for better efficency? Well, better mileage means less fuel... which means less Pollution. So you see, more pollution means less pollution because of efficency! GOTCHYA!
So see we are reducing Pollution and saving Murica money at the same time!
We must be geniuses in our own minds!
