The F-150 has a 23-gallon fuel tank size, just in the Regular Cab and SuperCab versions. There are optional tank sizes that follow the other trim levels of the 2021 F-150. The 23 gallons of gas may be equipped in the Regular Cab and SuperCab trim levels, but the SuperCrew® models use a 26-gallon tank size to fuel the 2021 F-150.
The Ford F-150 has more than 550 miles of driving range on one tank of gas in the standard model of the 2021 F-150. While that range of miles is the standard output, the list of Ford F-150 models means the maximum range will vary based on the engine and drivetrain that’s selected. The standard 3.3-liter V6 engine gets up to 20mpg city and 24 highway MPG, and the optional, more powerful 5.0L V8 engine gets up to 17 MPG in the city and 24 highway miles per gallon.
The Ford F-150 uses a 3.3L V6 engine which makes 290hp, certainly an eye-opening number. Similar to the amenities listed above, the engines and capabilities change with each trim buyers choose. A 2.7-liter EcoBoost® V6 produces 325hp and enhanced results in fuel economy. The available 3.5-liter EcoBoost® V6 engine makes 400 horsepower, and the larger 5.0-liter V8 engine produces 400hp. No matter which engine you select, an incredibly reliable drive follows. The 2021 F-150 continues to lead the charge for mixing durable performance and power, breaking the stereotypes of what trucks can be.

Ray my service provider was Great at communication. Fast service. Great place. Would recommend to everyone. Thank you
I had a great experience getting an oil change today. Hunter Coleman provided top-notch customer service. He was very kind, fast, and kept me updated the whole time. My car was ready quickly, and the service was smooth from start to finish. I will definitely come back. Highly recommend Hunter! Lastly, the coffee was very good.
Came in for an oil change. The adviser was professional and my service was completed within the timeframe given.
Great customer service and repairs. Dillon my advisor did an awesome job helping me out. I give him 2 thumbs up. Tank you
Freddie Seaboch was courteous, informative and knowledgeable. The staff also were attentive when pulling into the facility and didn’t leave me hanging like other dealerships.
This dealership is really easy going, the attention that is given is spectacular especially the way David treated us was great! Makes the process better, fast and not stressful, always gives us a good experience
Resolved all issues. Could be more willing to hand out loaner vehicles. Overall good Jod
I believe the gentleman’s name was Ricardo, but he was excellent and he informed me of what was happening and why. This may seem obvious and simplistic, but I personally really appreciate people to talk to you. They ask how your day is. They tell you the things that they found or didn’t on your vehicle. Because my truck is how I feed my family. So it may not seem like much, but treating someone in that manner goes a long way. So thank you.
I took my 2017 f150 5.0 for an oil change. The service was great, and they had me out in less than 40 minutes
Lynne Thurmond is always attentive to our needs. The service is done in a timely manner.
Fast friendly professional service performed on quick notice. Service advisor Ricardo Portillo exceeded expectations and would recommend him in future services.
Great experience as always. They’re quick, communicative and trustworthy. Great service and very friendly. Hunter was very helpful
Jonathan M was great! Great service and got me back on the road in no time!
Ray Luna in service delivered an amazing service experience. Very professional, friendly and knowledgeable. 10/10 experience thanks to Ray!
I went in for toe link replacement, which they did, but I also asked about a rear alignment. They diagnosed it and came back with about $5,000 worth of work that they wanted to do with it and would not do the alignment without the other work. It wasn't really explained to me why or how it made sense. Upon picking up my vehicle my advisor wasn't there so someone else checked me out. They were smug and rude and when they were having trouble starting my car (a Ford) they blamed me for not telling them how to ... Read More DealerRater - Jul 31, 2026
Jorge made buying our two new vehicles a great experience. He was friendly, knowledgeable, and easy to work with. He kept us informed throughout the process and made everything simple. Highly recommend asking for Jorge if you’re looking for a new vehicle!
They perform an authorized service without providing an estimate and review link for the requested service. They tried to only sell a bunch of unasked things only based on the miles not based on previous services. They were rude and yeilling and kicked me out I have spent roughly about $13k here and I am going to take my car elsewhere.
Robert was very professional and kept us inform on the status of our F150. Great customer services. I would definitely recommend your dealership.
I have visited the service department twice. My service advisor Jonathon Munoz has been great. Very friendly, helpful, and eager to make sure your visit is exceptional.
Shoutout to Lynne for working with me and the services I needed. I didn't have the funds to do all of the needed services, but she helped me figure out a way to work on them over time.
Everyone I have met and dealt with at this Dealership is Friendly, Knowledgeable and enjoyable to work with
Everything was great. Got in fast and quick. Would recommend to everyone to come here and do business.
Lynn was absolutely wonderful. Kept me updated at every turn!!! And she followed through with everything she told me.
The services performed were done quickly and with care. The customer service was excellent. The staff is very knowledgeable and the prices are reasonable. excellent marks all around.
Always a pleasure to use the service department! Friendly advisors and never pushy, always courteous and efficient!
Great phone service. Easy to schedule and get service done. No hassle. No wasting time on extra questions. Stated what I needed and got exactly that.
Con artists upholding the reputation that car service organizations will rip their customers off. Took my truck in for what should have been a quick and easy fix to a plastic piece that fell off the bottom of the truck and the front grill replaced. I didn’t get in any accidents or have any impact to the vehicle so I have no idea what would’ve caused these parts to fall off. I was quoted over $2000 to replace these parts by group one Ford. I took the exact fixes including parts and labor to three other repair places in ... Read More DealerRater - Jul 17, 2026
Received excellent service from Chris Jones and Raphael Lee while test driving and buying a 2025 Ford Bronco. Initial sales price was very good too.
Typical auto industry, paid for brand new car, wired the money DAYS ago and no one can be bothered to look up the payment so we sit here like fools waiting for a vehicle that has been paid for but we don’t have . Totally ahit deal! Thanks Group 1 Fraud!!!
Very kind and considerate service staff with actual accurate time frames and good service overall.
Really nice people and was easy to communicate to. Transaction was smooth and I go every time.
Great customer service and sales staff. I was happy with my trade and purchase values
good experience at the dealership. everyone was helpful during my time there from start to end.
I was greeted in a friendly timely manner. The service advisor Lynne was amazing explaining everything needed.
Alejandro Zamora was my service adviser and he was able to get my vehicle back to me in great shape and made the process pretty strait forward throughout my experience at Group 1 Ford South Austin
The service was excellent and efficient. I will definitely be back the next time I need service.
Eric made the process pretty easy and was not remotely pushy which we appreciated. We ended up buying two cars at the same time and they handled that process for us.
My service advisor was the Best, She got the service work done on my Truck in record time . She advised me on getting tire tires rotated and She got it done .The entire service team worked together and did a Great Job !
Ray was exceptional! In letting us know what was needed for our Bronco! Will definelry recommend.
I was very happy with the thorough evaluation of my vehicle and superb repair department
Great customer service with Jackie! Highly recommended going to see her when you need excellent care
The service was great. Very easy to work with and was not pushy on service I did not want.
Got taken care of immediately, staff communicated with me efficiently and kept me updated every step of the way.
I had my Bronco Raptor serviced and it was outstanding. Easy to book, quick check-in and great service. I will definitely not hesitate to take it back as needed!
Service writer, Freddie, was very concerned and proactive with the needs of our service request. I look forward to having him take care of our automotive requirements in the future.
They're responsive and want your business in the beginning, but then once you buy the vehicle, once you leave there they're almost non-responsive and won't help you. I bought a Ford F-150 and it has water/moisture inside the tail light. The day I bought it was raining, And then they washed it, So I assumed it was from either the rain or the wash. But now 10 days later the moisture is still there and getting worse. They won't make it right. They said I have to pay for it on my own. It's going ... Read More DealerRater - Jun 24, 2026
The quality of customer service was outstanding. Alejandro got my vehicle in and out. Great work and communication!
Awesome customer service they got me in and out and under an hour with oil change and tire rotation
It took a couple of days to get it to a tech for a warranty claim but that's to be expected these days. My service writer, Freddy, responded by quickly SMS, whenever I texted him. My tech did a perfect repair and the F150 PB came back better than when I bought it.
Lynne was excellent to work with! Highly recommend using her to help with scheduling a service and providing professional services!
It is always a pleasure to find Mr Evan’s at the service desk. He really takes good care of all my vehicles needs and he recommends what is needed . The dealership could be proud of his work ethic and quality. Thank you Sir.
Good service. Good communication. Thorough inspection of my vehicle. Made it a very easy and painless process.
Lynne was an absolute joy to work with. She constantly gave me unprompted updates and delivered my car on time and repaired accordingly.
The service was fast friendly and easy. The waiting space is nice, would recommend to friends
I brought in my 2025 Mach E for regular maintenance. The process was simple and the service department was very professional and pleasant.
This dealership is suffering. I have been a customer for over ten years and the change in ownership and management has caused a serious problem with quality service. Ford is not a company with that reputation so Group 1 will need to improve in a big way to be a representative of Ford
Excellent support and first class service, with excellent follow-up and communication by Lynne Thurmond.
Bold faced liars. Terrible experience. Nothing went smoothly. Sales associate Serena was terrible and unknowledgeable. Nothing was done when I got there like it was supposed to be. Was told there was no warranty when it's clearly stated online that it does include a warranty. STAY FAR AWAY FROM THIS PLACE!
Our service manager was great, Lynne. My biggest disappointment had to do with scheduling the valet. Pick-up went beautifully. I was told I’d have my car the next day and when it was ready was told the drop-off wasn’t possible. I was then made to feel guilty that I was insisting it be dropped off as promised. The manager, Andrew, basically told me there were no guarantees, the service was free, and if I wanted my car back as promised, I’d have to pick it up myself. Without spending money on an Uber, that wasn’t possible .. ... Read More DealerRater - Jun 11, 2026
Unfortunately, due to undisclosed damage that remains unresolved and exceedingly poor communication I have to leave a bad review. Cannot get anyone from the dealership to respond to phone, email, or text to resolve this safety issue in the 2023 Audi Q4 I purchased April 11. Love the car! VERY DISAPPOINTED in this dealership!
I went without an appointment, and they happily assisted me. They even sent me a video of the maintenance work. Ricardo Portillo explained the entire procedure to me in detail. service—prompt and professional.
Alejandro “Alex” service advisor was great at helping me and my truck! Great customer service!
Dealt with 3 different service rep and all were helpful and respectful. A Tech even rode with me trying to figure out what the mystery noise could be. We live in Round Rock but after the service we received from Ford dealership near us it was worth the 1hour drive to get to Group 1
Went to get my vehicle serviced and the staff is always great and very helpful.
Despite the change in day/time of servie, the staff, especially Lynne, were extremely accommodating and clear in the setting the expectations for care. It was really great to receive a video of the inspection that I could approve from my phone before they returned the car; shows great transparency in an industry where it could often be questioned.
The buying process went smoothly for the second time in less than a year with the same salesman Ben Beasley. I will always recommend group 1 ford
Friendly and knowledgeable staff. They were willing to do what it takes to make a fair deal happpen.
I had a great experience at Group 1. The staff was very friendly and the service was very quick!
Great service’ discussed plan prior to starting, everything was as expected and the service managers was in contact
Group 1 Ford has always taken care of me, Jackie was awesome helping me. Very transparent with the whole process.
Arrived a little before my appointment time. Taken care of pretty quickly & ready to go! Great friendly service
Amazing! Jackie is the best in the service department. Great experience, as always. Highly recommend.
Freddie was a great service advisor. He helped me through the whole process and explained everything pretty clearly.
The customer service and attention to detail was amazing!! Ray Luna went above and beyond and made me feel like a family member and not just another customer.
It was so nice to have an advisor who clearly understood cars and my situation. I will make sure I find Jonathan for all my services!
The dealership is quick and efficient. My advisor Jackie was very good at keeping me informed about my vehicle, and was very personable.
Easy to make an appointment online. My service person, Hunter, was attentive, informative and personable
Erik Gustafson was friendly, professional, and kept me informed throughout the process. He answered my questions, completed the service in a timely manner, and made everything easy from start to finish. Excellent customer service.
Lynne was amazing in all ways! She was very helpful, detailed, and made me feel satisfied walking away from my service. Made me really want to continue to come just for her service and the way I felt at the dealer.
Robert provided excellent service! I came in for an oil change and to have a recall checked. When I called beforehand, I was told the process could take up to half a day. However, Robert had everything completed and got me in and out in less than two hours. I truly appreciate his professionalism, efficiency, and outstanding customer service.
Hunter in service was very helpful. He listened to what I thought was wrong and was able to direct the service team appropriately. He communicated the progress along the way.
They are condescending when speaking to you, they try and add on services you don’t need. They made me want to never buy another ford again for the rest of my life
I was able to get my truck repaired and tires replaced in and out same day. Thanks again for the speedy performance.
My 2nd visit while I was here from California. Hunter excellent service writer! Thank you. The technician must be good too as my truck made it out of the service department. Thank you too.
Quick, courteous, got oil change in 45 mins.Brought my car and on the road.
Every one has been so great to our family. Especially Jackie Wiora. I trust that young lady and her work ethics. She deserves a raise. BRAVO ZULU JACKIE
Called to set an appointment for service warranty work. Appointment was set. When I arrived for the appt., no record of it. Was told appointment only gets you in queue with others with no appointment. So appointment is useless. My warranty work for back-up camera took 1.5 days. The service department claimed my car battery needed replacement (battery was under warranty from retailer so I declined). Turns out that there was nothing wrong with the battery. They tried to sell me something I did not even need. Communication was poor as I was originally told by the service rep around noon ... Read More DealerRater - May 21, 2026
Not an ideal repair as multiple parts arrived damaged, but communication was good and the repair was completed.
Excellent service team, transparent communication, fast repairs, friendly staff, and truly outstanding customer care throughout.
Excellent service good communication clear description of work to be done no upsell clean waiting room
The Ford Dealership gave excellent car service help. Got an oil change. Perfect customer service from Hunter.
Hunter did an awesome job with everything Introducing himself, written list of issues, follow ups, He handled everything professionally and courteously He is great at his job Enjoyed my time and experience with Hunter
My advisor Jackie Wiora is excelente on her job John Sullivan is always caring for the customer I’m very satisfied
Joshua in service was helpful, timely, and personal. The vehicle was taken care of and good recommendations for upcoming service were communicated.
Was quick to schedule me, was clear about the work, and was thorough with the work.
Walked in without an appointment to addtess recall on software issue. Was informed it woukd take an hour. An hour later the work was done. Topped off fluidd and did a basic check at no charge. Totallysatisfied.
I waited 10 minutes for my “appointment” for an oil change, was not warned how long it would take. It ended up being over two hours long
Professional service, clean waiting room. Nice people taking care of business. Prompt and easy to schedule.
Guys in service today were great once again. Felt like VIP. Recommend this for sure
Great staff in sales and service teams, and a very clean and well-maintained environment
