RAM EcoDiesel a Flop for Towing

On edit. Just because an engine is operating at below its rated HP does not mean it is struggling less than one that is. It depends on the design parameters. A 2.5L F1 engine producing 300 HP is not guaranteed to be more reliable than a 4L V8 rated at 300 HP, just because the F1 engine is only operating at 40% of its rated 700+ HP.

Good, now you know that there is a difference between American and European power numbers. Either way you put it the Ecodiesel is underpowered compared to the 2.7L Ecoboost no matter what slow speed you are willing to go up the mountain at. Why Ram rated that Ecodiesel to tow more than the 2.7L Ecoboost is beyond me. Maybe those that designed the Ram 1500 Ecodiesel considers only being able to go 50 mph towing less than its max rating is acceptable while Ford thinks you would be able to at least keep the speed limit when towing the max.

That's intelligent. :h

Because what you stated wasn't. Since you are competent at Google searching, why don't you look up the cylinder and boost pressures of the Ecoboost and Ecodiesel so you can understand why I said "no and no" to your assumptions.

On Dec. 29 we hooked up our fith wheel and headed down the I5 to Southern California. We just got back Friday and during that time I never saw one pump labelled #1 but plenty labelled #2 and I have never seen a pump labelled #1 where I live.

The fact is, refineries do not switch to just #1 in the winter, they blend #1 and #2 according to area climate and season. I suspect that on the west coast where nightly lows are rarely below a few degrees below freezing regardless of season, little or no #1 is required in the blend.

I never stated winter diesel had to be #1 one only, and asked if they never had number #1 either blended with #2 or straight. Here in south Texas, our winter diesel is a blend of #1 and #2, but the fact still remains that you get less fuel economy versus straight #2 regardless if it is only #1 or a blend of both.

Again, you stated that you don't like to have to go WOT on your equipment earlier. Fact is when towing 7,200 lbs, you would have to be closer to WOT in the Ecodiesel versus the 2.7L Ecoboost because the Ecodiesel is underpowered in comparison.
