6.4l 8 speed towing review

I can guarantee that a 6.4L Hemi will put out way more CO2 than a tuned Ecodiesel if your personal reason is to be environmentally friendly. In fact, all gas engines emit more environmentally harmful CO2 than a diesel equivalent. The only thing a tuned diesel with a DPF puts out is a lot of NOx which is only bad if you are in a highly populated with high temps, but will do nothing to you in lightly populated areas with cool temps where it has a chance to dissipate into the stratosphere to become good ozone.
