Ford has been very proud of its new 7.3-liter V8 engine that will find its way under the hood of the 2020 Ford Super Duty line. Ford has spent a lot of time bragging on this engine, which replaces the outgoing Ford V10. Ford has put a lot of effort into making the engine as durable and cheap to maintain as possible for fleet owners. One of the key factoids about the engine is that Ford has improved the oil management inside the 7.3-liter Godzilla V8, which has allowed it to extend the oil change intervals.
From the factory, the 7.3-liter V8 engine will have oil change intervals of 10,000 miles. Ford notes that the engine has an oil minder to monitor the usage. The 10,000-mile oil change intervals are a big deal for fleet customers. The outgoing V10 engine has 7000-mile oil change intervals. The 7.3-liter V8 displaces 445 cubic-inches and makes 430 horsepower and 465 pound-feet of torque.
The engine will be paired up with a 10-speed TorqueShift that will be used through the F-600 chassis cab. Ford Super Duty chief engineer Mike Pruitt says that the automaker “put a lot of thought” into making the engine “bullet-proof.” Ford wanted to keep the engine simple, so the Godzilla V8 went back to a cam and block design. Pruitt notes that the engine is smaller, more compact, and has fewer parts. He also notes that Ford wanted commonality around the medium-duty truck to make maintenance simple, which is important to fleet businesses.
Some indication of fuel economy in the big V8 has surfaced from real-world tests. Despite the large displacement engine and the horsepower output, reports indicate that an F-250 with the Godzilla V8 under the hood and 3.55 rear axle ratio was able to achieve 15.5 MPG on a cross-country trip. Certainly, truck buyers don’t purchase for fuel economy, but it’s nice to know that the truck gets decent fuel economy.

Enabling it to gain market share, too.
This is no wagon turned SHO, either.
A simple but potentially useful idea.
Sales increased 6.6 percent to 1,492,905 units during the first eight months of 2025.
It was encouraged by Ford's future EV plans.

I would still be more comfortable at changing oil at 5000. I just like an engine that has fresh clean oil in it.
BTW, is BLUEBIRD going to use this engine in their VISION school bus? They are using the V10 for the gasoline and propane versions at the present time.
Should be “cam in block,” not “cam and block.”
I pulled that from a quote attributed to the chief engineer from the program, I guess he could have misspoken but not being an engine guy myself I went with what he said:
“We’ve put a lot of thought into the engine about making it bullet-proof, keep-it-simple so we went back to a cam and block design,” Ford Super Duty chief engineer Mike Pruitt said. “It’s a much smaller, compact engine with fewer parts. We wanted that commonality between ourselves as well as the medium-duty truck and keeping that simplification for maintenance purposes which is very important to the fleet business.”
This will be a hit with motorhomes.!
The new FORD 7.3 GODZILLA V8 has a Crankcase oil capacity of ??? Quarts.
Wouldn't that capacity be relevant to this article?
manual says 8qts including oil filter
Put it in a new 2 door Bronco
My 2019 Mustang EcoBoost Premium has a 10,000mi oil change interval too.
Looks like it could be a really good option for future marine applications too.

I have a 2020 F250 with the Godzilla V8 - I have 3200 miles so far and with mixed driving I do average 15.5mpg. The engine is a beast, tons of power, GREAT old school V8 sounds, etc. Do the math vs purchase of a diesel - if you don't tow all the time and your are maybe heavy weekly, etc. this a great option. I put about 50K annually for work/pleasure on a vehicle - assuming a 6.7 diesel might get 19.2mpg and I get 15.5mpg - Costco sells diesel and regular for the same price in my area (currently $2.69/gallon) - payback at 50K miles per year and $10,000 premium for the diesel engine is over 6 years! If you drive less the payback will be much longer ... no brainer.
i went with 7.3 gas in a 2020 f250 i only have 600 miles so i cant tell about M P G yet but i can tell you one thing im SICK AND TIRED of power stroke diesel's junk 6.0 6.4 6.7
I am averaging 14.8 mpg city/highway in normal shift selection, 15.9 eco mode. I am at where I was with my Toyota tundra, with a bigger and heavier truck. Very happy with this Godzilla engine.
