I had the diesel engine. Mileage was unbelievable, really quiet, big and comfortable seats. I’ve owned a BMW, Mercedes, Toyota, Ford, Cadillac, even a Corvette, and this is the one I miss the most.

High reliability, great fuel consumption 32mpg in highway. The synonymous of comfort, high tech and safety. So sad Ram will discontinue the eco diesel next year.

Always wanted an eco diesel. Got a good price on a 2021 with many options and the crew cab. I took it on a long road trip with my wife. The second day I had it and it drove great, we drove through a flash flood and pouring rain,the four-wheel-drive auto option gives you peace of mind. I calculate at the pump when I fill up the first full tank was over 31 miles per gallon. Also I found diesel for a really good price near me . I have had it for a few weeks so far it is a great truck and I will update my review as I own it longer.

Eco Diesel is the best pickup truck I've owned yet

115,000 miles and this truck has never let me down or been in the shop for any repairs. I do all my own maintenance. Regular oil changes with approved oils only. Filters, tires, one set of brakes and that's it. The cab is comfortable and the drive is quiet. I get outstanding fuel economy, and used the truck to tow a fairly heavy tow hauler for several years before buying a dedicated towing vehicle. I had intended to sell the 1500 when I purchased a 2500, but the ride quality, comfort and fuel economy made that decision too difficult and I now have two Rams in the driveway. One is a daily and the other is for heavy work. The Eco Diesel motor is quiet, composed and powerful. At 60,000 miles I did a stage 1 tune for the engine and the transmission and the truck is nearly as quick as a hemi, but far more composed and quiet. I commute 40 miles each way to work and usually average around 25 miles per gallon. It's a shame the 3.0 diesel engines have been discontinued. My previous ram was a 5.7 hemi and I would not want another. That motor sounded like it was going to self destruct and I'm glad I sold it before it had any major issues. The Eco Diesel reputation isn't great, but regular maintenance has paid off in my case. I expect to have this truck for many years to come. It's holding up great, still looks sharp, the interior is holding up well. The truck still looks and drives amazing.
