You can run E85 in your Maverick LOBO?????

From what ive read you don't want to run a full tank of E85. Run a blend of E85 and Premium. So states 93 Octane is available out of the pump. In my area we can only get 91. So 4 gallons of E85 and then top the tank off with premium and you get 93 octane. Also 4 Gallons of E85 at a $2.30 per gallon makes the fillup way cheaper.

Dude ! You shouldda got the Hybrid.

My Ecoboost will never see a drop of E85.

If my money was so tight I had to burn crap Idda not thrown down on a $40,000 truck.

You should not use any E85! In a stock EcoBoost!

What is the fuel type for the 2024 Maverick Gasoline (Non-Hybrid)?
Your vehicle is designed to operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87.

For the best overall performance, especially in hot weather or when towing a trailer, premium fuel with an octane rating of 91 or higher is recommended.
Fuel Recommendations and Restrictions

• Top Tier Detergent Gasoline: It is recommended to use Top Tier detergent gasolines where available to help minimize engine deposits and maintain optimal performance.
• Prohibited Fuels: Do not use diesel, fuels containing kerosene or paraffin, fuels with more than 15% ethanol (E15), E85, methanol, or fuels with metallic-based additives (such as MMT).
• Altitude Warning: Using fuel with an octane rating below 87 in high-altitude areas can result in engine damage that may not be covered by your warranty.

Safety warning(s) apply to this topic. Ask about safety precautions for details.

I noticed earlier that you mentioned you have a tuner on the truck. Is it tuned for that ethanol blend? If so, cool, keep having fun. If not, it might be a bad idea...

If you want to run full E85 on your 2.0L EcoBoost, you cannot just pour it into the tank. The factory fuel system isn't designed for it, and you'll hit a "lean" condition very quickly because E85 requires about 30% more fuel volume to maintain the correct air-fuel ratio.

Here is the breakdown

1. The Hardware Limitation

• Fuel Injectors: The stock injectors on the 2.0L EcoBoost do not have the flow capacity to handle full E85. When you go wide-open throttle, the injectors will "max out" (they can't open wide enough or long enough to deliver the required fuel), causing the engine to run dangerously lean. This is a one-way ticket to engine damage.
• Fuel Pump: While some tuners say the stock High-Pressure Fuel Pump (HPFP) can sometimes keep up for basic E85 or E30 blends, it’s often a bottleneck. Most professional setups for "full" E85 will upgrade the injectors first, and often the pump as well, to ensure you have plenty of overhead.

2. The "Tune" Is Non-Negotiable
Even if you upgraded every single piece of hardware—injectors, pump, and lines—you cannot run E85 without a custom tune.

• The ECU (computer) needs to know the exact ethanol content to adjust the ignition timing and fueling.
• If you just swapped the parts and didn't tune it, the computer would still be trying to calculate fuel based on gasoline parameters, and the truck would run terribly (if it ran at all).

3. The "Middle Ground" (E30)

Many people in the EcoBoost community don't go to "full" E85 for this exact reason—the cost and complexity of the fuel system upgrades. Instead, they run an E30 blend (mixing roughly 3 gallons of E85 with 7 gallons of 93-octane gas).

• This gives you the knock-resistance benefits of ethanol (allowing for more timing/power) without needing to replace the injectors or the pump.
• Even for E30, you still need a custom tune optimized for that specific blend

Ecoboost and E85 do not mix. The AFR will bee way too lean, E85 need a much richer AFR to burn. The only way is by custom tuning.

Recommending a Hybrid to a gentleman who owns a tuned & modified Lobo?

The OP’s title of “Drive it like you stole it” means driving recklessly fast with utter disregard for the owners manual or warranty.

If you save a few dollars making your own homemade “go fast” blend of fuel - that is like killing 2 birds with one stone.

Get a Hybrid lol

In His OP he states His Maverick is tuned!!

Read that, but should have added that mixing by gallon does not equate to a specific E blend. Only testing can determine the % of ethanol and gasoline. The marked E blends on pumps can vary a lot.

= No more than 85% (maybe?)!

Yes I have a tune for a blended E85 and premium. I’ll let you guys know when and if anything happens. If you think it’s crazy remember your vehicle will be fine your not doing it, it’s my vehicle and I am ok with whatever consequences. I get it some people don’t like breaking the rules or modifying there cars and I respect that. If it bothers you just take a deep breath calm down and remember it’s not your vehicle.

I'd be the last to complain about modding a vehicle. I bought my F150 with the intention and budget over $10000 specifically for aftermarket and DIY modifications.
Testing a blend of ethanol and gas is easy and the test tools inexpensive. Mix as you feel right then test for accuracy. I have seen E85 test from 65% to 90%.

Back in 80's I was selling real estate and was involved in a multiple (7) property string of sales with closing contingencies. One of the sellers was short of funds so I agreed to take a Cadillac pos for $820 for part of my commission to let everything close. I wound up keeping it for a couple of years. It had the 4-6-8 cylinder v8 which varied number of active cylinders to save gas. That feature more or less worked, but occasionally the ice would die after 9-12 miles and would not restart for 30+/- minutes then after 9-12 miles do it again. There were several others having the same problem. Nobody was successful in fixing problem on the few with the issue. One day I had it happen again and the lightbulb lit up. It only happened when I bought gas at the discount station so I took it to the non dealer repair shop working on them. (Dealer was changing carbs, etc and couldn't figure problem out either). Told shop owner and he said "I've done everything but check gas". This was when alcohol was being introduced in pumps. Test results showed 30-35% alcohol in gas which caused the sensor to misread and the fuel was being leaned up until ice couldn't run. After sensor warmed up ice could run for sale longer,!!!!
