7.3L Gas vs. 6.7L diesel

[plethoragreen]

The only issue I see with this is the risk of the uknown and warranty. Say after 5 years your engine blows, the gasoline one, then perhaps the diesel was the better buy. Although I myself got a 10 year, so at least for 10 years it'll be comparable, apples to apples, if I had purchased a diesel.

I think that's a fair point. However, I think a more apples to apples comparison is Gas vs Diesel sans emissions systems. Isn't it cheaper to replace the entire gas engine than it would be the emissions system alone on the 6.7? There are more parts there that could break out of warranty that renders all the benefits and efficiencies of the diesel moot.

Most examples for both sides are pretty anecdotal and it again just boils down to everyone's budget (where they want to spend the money) and priorities. A case can be made either way I just don't abide by the idea that if you tow an 8,000 utility trailer once a month you need a 6.7 (not anyone here but I've had those conversations a plenty).

I'm hoping to have mine in another month and from those I've talked to personally that are driving the 7.3 (and doing a lot more towing/work than I plan on) I'm not going to be disappointed in the slightest for the miles and use I have for it.

Exactly. Friend has a diesel with only 60,000 miles on it that he bought new with an extended warranty. He had to get the DPF replaced and they didn’t want to cover it, but after a bunch of back and forth they did. All the emissions equipment are very expensive if they need to be replaced which seems to be more and more often lately.

Out of curiosity, how old is the truck with 60k on it? From my understanding it is the short/frequent trips that harm the emission/exhaust system more than anything else. Quick little low mileage trips don't generate enough heat for the length of time necessary to keep the system cleaned up?

Another thing to note fellas... EVERYONE seems to have their diesel vs gas calculator... the calculator works to get a "snap shot" of today's fuel cost. When fuel cost rise the difference between gas and diesel stays relatively the same as far as a "premium" over the cost of regular gas. Enter in your calculator higher fuel costs... say 3.20 and 3.40 or 3.50 (diesel being 20-30 cents higher) and the more efficient diesel starts to really show off.

Fuel filters can be bought online for around $55.00 and can be done in about 15 minutes one Saturday morning... easier than an oil change by far in my opinion.

Oil change is gonna be about $100 at the dealer for a diesel.... My old 1/2 ton was over $70 cause of the newer 0w30 requirements only allows for synthetic oils... $30 dollars more is not that big of a deal. The overall "maintenance" IMO is not as big of a factor as its made out to be.

For whatever reason, some people come across as seeming to think others are idiots cause they didn't buy the same motor for the same reasons as they did... (I said "seeming" so don't bash me for that comment).

Bottom line, buy whatever you want for whatever reason that you want, they are both great vehicles. Gas motors in general have come along way so both should last a long time.

I am not bashing anybody for what they chooses. Just pointing out the old adage of extra cost of diesel will quickly pay for its self is rapidly changing.

With the modern gas engines the gap is narrowing from a $ saved on increased fuel economy. The diesel fuel cost is a difficult thing to gauge in my area. Right now diesel is $0.02 A gallon cheaper than 87 (2.21 vs 2.19). For example the fuel price gap was at $0.25 a gallon more for diesel when I ordered 3/17/20. It peaked at around $1 more earlier in the winter. I have a diesel tractor so pay attention to pricing on both. What I have noticed is when fuel prices are higher in my area the gap between the two increases substantially, up to 40% price difference in recent years.

In my calculations I Initially used a conservative 10% price difference at various fuel Cost levels when playing with the numbers since the price gap on fuel here is not very consistent at $3 for gas and 3.30 for diesel pay back for me is still 148K miles. Ironically it is about about the same using today’s prices. Taking maintenance cost difference out it would still take about 130K miles to break even for me towing 10K or less 50% of the time. At that rate would take me well over 15 years to realize the fuel cost savings.

On the flip side my buddy that is running the 2020 6.7L payback is much better. He frequently tows closer to max rating. Using the same formula but with 75% of the time towing and today’s fuel cost it takes him a measly 50k miles to break even. For him the diesel is definitely a better fit $ wise with about a 5 year payback. The answer is not a one size fits all thing if just going by the $. There is also other reasons to choose one over the other just glad we get the choice so we can all get a better fit for different applications.

It’s a 2017 and he’s a contractor so he is using his truck as intended.

for the 6.7 After the warranty is up it would be a no brainer to delete the DEF.

In my 2013 dodge 6.7 Cummins the DEF Hester went right at the 5 year mark and it was cheaper to delete the system then to replace the heater.
it now runs better than ever and better fuel mileage.

I have never owned a SD but I will be getting the 6.7

 

[Whyte Rhyno]

As everyone says, unless you tow a lot get a gas. It'll handle better off-road and gets decent enough mileage. However, now that diesel is cheaper than gas in some locations, the diesel might offset it's price quicker. I got the diesel because I love the power numbers. And resale is amazing when it comes time for a new truck

 

[IceSoldier88]

I tow my tow hauler at least once a month, and trailer with SxS/ATV/Dirt bikes regularly. Live in snow country. So I wanted the better MPG, and resale value. But also iv never had a diesel and finally able to get one. The Tremor part is what completes the package. As I go offload a good bit. But don't offload.

Now your like what, he just contradicted himself. LOL. I drive through farm fields, seasonal roads, snow, and what not. I don't go hardcore offload. So diesel was my choice.

That's why I love the country we live in. The freedom of choice. Even if you don't need something according to anyone, you're free to choose.

Ordered a F350 Tremor 6.7L diesel and a 7.3L gas truck. One of my dealer deposits will be forfeited. Haha. I'm most likely going with gas as the operating cost numbers are pretty close, that you don't break even on cost for about 11-12yrs.

Assumptions: Average 15,000 miles a year, diesel fuel .20 cents more than gas on average
Diesel 19 mpg 1250miles/19 = 65.7 gallons
Gas 12 mpg 1250 miles/12 = 104.1 gallons

The delta is 38.46 gallons of gas per month at 2.00= 76.93 dollars more fuel cost per month. 76.9 x 12= 922.80 per year. I will save about 10,500.00 when you include tax on a gas truck purchase over the diesel. 10,500.00/922.8= 11.37 years to break even on fuel alone not counting added maintenance cost for diesel motors. I need the payload for truck camper and won't be towing much. Power on the 7.3L is pretty good. If you got a non Tremor FX4 Super Duty 7.3L with 3.55 estimated 15 mpg makes the equation even better towards a gas motor for light towing/added payload use.

Some guys just like diesels though!

Everyone looking just needs to determine their priorities; their needs over wants.

The 7.3 likely has everything I could ever want in terms of towing, hauling, or even offroad prowess. The diesel is overkill for me and an extra expense I do not require or want.

With the diesel you are paying a premium but hopefully you're buying it to be used in a way that necessitates it over the gasoline's relatively high limitations.

Well after being on the fence for almost 2 months the decision is over. 6.7L diesel won out. Close decision. I hard balled the dealer a bit to come off MSRP and I was quite surprised they did! 2500.00 off made the diesel choice easier. They is a 2020 F350 7.3L gas coming to Maxwell Ford Austin Texas (build date 8/10/2020) Vin#1FT8W3BNOLEE18822 if any of your buddies are interested. Could probably make a good deal since they already have my non refundable deposit. Haha

 

[PapaRaptor]

Ford gives you 5 year or 100,000 miles on emission on the 6.7

I saw something on the internet ( so it must be true) Feds say 8 year 80,000 miles

I did have emission trouble with my 2015 Chevy D max and GM sent me a letter of additional warranty for 10 more years or and additional 110,000 miles. So maybe if there is a problem on record within the factory warranty Ford will take the high road and extend the warranty.

I feel throwing money at emission parts and equipment is a waste.

Congratulations! A Tremor is a Tremor.

That’s with the dually.

 

[Greggg2018]

Correct. Tremor package doesn't some in dually only SRW. I have a F350 Tremor and max tow is 15K bumper and 21K gooseneck

 

[Pompey]

That’s with the dually.

How? It says it’s for the F250

They do here in the 5 county area in Wisconsin ( Milwaukee) I have had to have my D max tested twice in last 5 years thank full I did not remove any equipment
