I review a 2022 RAM 1500 EcoDiesel and a RAM 1500 5.7L Hemi and compare the two engines as a Licensed Diesel Mechanic to see if the extra cost of the Diesel option is worth you buying it. I break down the fuel economy of both the EcoDiesel and the 5.7L Hemi, factoring the extra cost of maintenance and DEF to give you guys the truth about this engine is cheaper to own.


I hope everyone is having a good weekend! After comparing the 6.7 Cummins to the 6.4 Hemi last week. I figured this would be another awesome comparison.

I use the EPA combined fuel efficiency rating to get a good comparison of both the ecodiesel and the 5.7 hemi. turns out the ecodiesel is 47% more efficient but factoring in that the price of diesel is 30% more expensive the ecodiesel comes away with only 17% more efficient.

we also factor in maintenance costs and that also hurts the ecodiesel as a diesel engines maintenance costs are always more expensive.

lastely we look at the cost of emissions and that really puts the ecodiesel overboard as it would take almost 1 million km to break even with the initial cost of the diesel engine vs the gas option.

I also personally as a licensed Diesel Mechanic think the Eco diesel is a bad engine. even if it truly turned out to be more cost effective I still wouldn't buy it. lesson learned here is buy the 5.7 hemi and you won't be disappointed
