TCO of Hemi vs Cummins

Could I get by with a 6.4 hemi, sure. I bought a Cummins Diesel cause I wanted it and the future options it creates.
 
Can't remember the last time i looked at the cost of anything related to my truck.

I always find it interesting when people go into such great detail and look at ownership so granular.

Wonder if their grocery budgets look the same?

Sample size of 1 and personal opinion on diesel emissions. If you’re averaging 18 mpg in a diesel, you probably don’t need the capability of a diesel. I’ve had 5 tanks in 30k miles reach 18 mpg. Averaging 15 so far with about 25% hooked up to a trailer.

I’m also borderline could go back to a Hemi or 7.3 Superduty given my usage. But have just enough elevation and straight up “want” the diesel.

A 100,000 mile Cummins for $31K? In my area, that is a pipe dream. At a bare minimum, that would go for $45K plus in my area, depending on model

Reasons to get a diesel:

1. I want it and can afford it
2. Tow regularly
3. I want it and can afford it
4. Tow heavy
5. I want it and can afford it
6. Tow at elevation
7. I want it and can afford it
edit 8. Boobs
9. Butts


(not sure I can afford 7, 8 & 9) :cool:
 
I went for a 6.4 because of all the nightmares I hear about emissions. Seems like the majority of threads posted with issues are something to do with the DPF. I wish I could go back in time to buy a pre-emission truck. Always wanted a diesel, just doesn't seem worth the hassle now (and extra $9000+).

Also, I am only towing an enclosed car hauler.. not some monstrous 5th wheel.

Bet the numbers change when diesel is 58 cents less than gas.

I was just thinking about this earlier today. funny I now find this thread.

I have never owned a diesel so please forgive me.

So the initial price is about 10K different between gas and diesel, no matter which brand you buy it seems.

Diesels seem to hold value longer, not sure why.

Maintenance seems to be higher on a diesel as are repairs. Not talking basic maintenance like filters and oil, but all the rest.

Gas mileage and price doesn't seem to be a big difference anymore like it used to be.

Everyone talks big about how much torque the diesel makes. That's great. But you still have to get all that power to the ground. Good when towing probably, but not good when empty. I can easily smoke the tires in my 6.4l Hemi.

They also talk about how many miles a diesel engine will last. Great. But the rest of the truck will wear out at about the same rate of a gasser, if not quicker because of the extra weight and power.

If you are towing all of the time, then yea, a diesel is great. That's why the big rigs run them.

But for most of us, a gasser may be the better route.

But then again, I could be completely off, never owning a diesel. :p

Brakes. Brakes. Brakes. The engine brake in the diesel will save you several brake jobs. I would guess about $500 or more per year?
 
I do my own maintenance. I purchase fuel & oil filters on Amazon in bulk due to savings (most of the time) Oil for 12 quarts is $39.00 for Valvoline 15w-40.

Premium Gas - 93 Octane is $3.74
Diesel - $3.14

30 gallons of 93 octane = $112.20
30 gallons of Diesel = $94.20

That saves me $18.00 per 30 gallons. From real world experience the combined MPG of the 6.4 Hemi averaged 13mpg combined including towing, city driving and highway. The diesel was 18mpg or more. The cost savings is $3 per fill up and I based that on 30 gallons. Once you factor in DEF it becomes almost equal.

Cost of Service -

6.7 Cummins - $12.00 for OEM oil filter & $39.00 for 12 quarts Valvoline 15w-40 changed at 10k miles = $51.00
6.4 Hemi - $9.34 for OEM oil filter $63.22 for 7 quarts of Pennzoil 0w-40 at 5k miles = $72.56 x 2 to reach the 10k interval on 6.7 = $145.12
Difference per 10k miles on oil changes is $94.12. Fuel filter prices are changing weekly so for both, I am going to say $60.00 at 10k miles
Total Difference for service over 10k = $34.12 for gas than diesel including changing fuel filters.


10,000 miles per year as an easy guesstimate....
6.4 Hemi = $2,876.92 in fuel, $145.12 for oil changes = $3022.04

6.7 Diesel = $1744.44 in fuel, $51.00 for oil change, $60 for fuel filters = $1855.44 + $8 per 2.5 gallons of DEF that will last 1500 miles is $53.33 over 10,000 miles
Total: 1,908.77

A difference of $1,113.27 per 10,000 miles in favor of the diesel. You also have to factor in 40,000 more miles of factory warranty. I use the discount off MSRP to subtract the option charge of a 6.7 and in my case it was 5k. So $4200 more than the 6.4 hemi. Based on this it take 3 years and 11 months to break even for THIS situation on these number averages.

The diesel is more efficient at towing with a better warranty and a much higher resale value. IF I didn't do my own service work then the 6.4 gas wins.


*This is just an example and my numbers might be off or different depending on where you are located. I was only using this as my personal example.


I can share my code to save either gas or diesel users between 10c to 45c per gallon, just send me a PM if interested.
 
93 octane is not required in the 6.4L. Gasoline is still under $3 with my fuel card at the wash joint.

I love the Cummins but didn't need one this time around. Do I regret not getting it? Sometimes...

It amazes me how some of you guys crunch numbers lol.....ain't nobody got time for that!

The 6.0's & 6.4 powestrokes were horrible. They didn't roll coal, just coolant. The 5.4 Triton gas engine wasn't the best either.

Ford new CEO is better than the previous one however with the shortages and supply chain issues I think it would have been best to not announce new models & focus on the quality control of the full size Bronco and F-150. The F-150 makes up 85-90% of Fords global profits. I'm done with Ford's multiple issues on every model from interior, mechanical and even reducing cost to not coat the underside of vehicles from rust or spray base color under the hood or engine bay.
 
I was just doing this comparison recently. Decided on the 6.4L gasser. The costs don’t break even in my calculations for too many years. Plus I wouldn’t be towing anything over 10k lbs for the most part. The diesel is more fun to drive I’ll give it that.

Great way to screw your 19+ cummins running 15w40 oil btw the hydraulic lifters cant work properly with that thick of oil

If you're pulling that heavy, that often, in mountains that would cause your engine brake to save you several brake jobs, you were never considering the Hemi in the first place.
