Hello!
New to the forum, had a 2011 JKU when I lived in Egypt and did a lot of deep desert exploration... Fast forward 10 years and im looking to get a Gladiator.
We have had several Mercedes Diesel vehicles in the family and my current daily driver is a 2015 Porsche Cayenne. Thus naturally I am looking at the Gladiator with the EcoDiesel. Of course I love the torque of the diesel but also really like not having to go to the gas station so often. I get close to 600 miles to the tank in the Cayenne, because it has a 26.5 gal tank. I was really sad when I saw the diesel Gladiator only has a 19 gallon tank.
Anyways, I have been doing a lot of reading on forum and have not come across anyone talking about the benefit of the EcoDiesel when at altitude. From what I remember from an engineering undergrad Internal Combustion Engine class, for every 1,000 feet above sea level an NA engine loses 2-3% of its power output.
So if we are talking about Denver, the Pentastar is down 10-15% power, up in the mountains at 10k its down 20-30% power. Have people with the Pentastar felt this? Any comments of those with a EcoDiesel, seems the turbo should have no issue making up for the altitude.
The attached picture was taken in 2013 at the Wadi Hamra (Red Vally) in the Gilf Kebir located in the south west corner of Egypt where Egypt/Sudan/Libya meet. 10 day trip, 1,500 miles round trip (~1,300 miles off road), 4 jeeps, 1 armed military escorts vehicle, 1 guide vehicle, 1 cook vehicle. Each vehicle had to carry its own fuel. I had 9 military jerry cans stacked in place of the rear seat plus a 35 gallon tank in the trunk (The Jerry cans on the roof in the picture are empty). No contact with civilization during the middle 8 days.
