What does flex-fuel mean on a Ford Escape?

Flexible fuel vehicles (FFVs) are designed to run on gasoline or gasoline-ethanol blends of up to 85% ethanol (E85).1 Except for a few engine and fuel system modifications, they are identical to gasoline-only models.

What is flex-fuel system?

Flexible fuel vehicles (FFVs) have an internal combustion engine and are capable of operating on gasoline and any blend of gasoline and ethanol up to 83%. FFVs have one fuel system, and most components are the same as those found in a conventional gasoline-only car.

What is different about a flex-fuel engine?

The main differences between the two lie with the engine and fuel system. The internal combustion engine of a flex-fuel vehicle is designed to run on more than one type of fuel — usually gasoline plus ethanol or methanol fuel, all of which are stored in the same tank [source: Chapman].

How does flex-fuel work?

Flex fuel vehicles have system alterations that allow them to properly run on an ethanol-mixed fuel. Changes to the system include alterations to the the fuel system and oxygen sensors. Gasoline cars can be converted to run on flex fuel. Unknown to their owners, many cars on the road today are able to run on flex fuel.

Is using flex-fuel worth it?

Cleaner for the Environment

Ethanol burns cleaner than gasoline, which means flex-fuel cars pump fewer toxic fumes into the environment. Flex fuel also contributes fewer greenhouse gases, making it a more environmentally friendly option than traditional gasoline.

Will flex-fuel damage my engine?

Many newer cars are designed to run on ethanol, which is called flex-fuel. More than once, individuals have inadvertently put flex-fuel into their gasoline vehicle. While this isn’t ideal and can impact the vehicle’s ability to operate smoothly, in most cases, no long-term damage is done.

Can you switch between E85 and gasoline?

A: Go ahead and mix it up. “It’s OK to go back and forth. Cars are designed to use any blend,” Monte Shaw, executive director of the Iowa Renewable Fuels Association, says. Flex-fuel vehicles can operate on gasoline that contains from zero to 85 percent ethanol (e85).

Does E85 clean your engine?

E85 is actually safer for your engine than regular gasoline is. E85 flex fuel not only powers your engine but also cleans your engine, fuel lines, and fuel injectors. That’s because E85 contains a high amount of ethanol, up to 83%. Ethanol is an excellent cleaner.

Is it better to use E85 or regular gas?

In an advanced engine, E85 can improve the engine’s fuel consumption. Despite the lower miles per gallon, flex-fuel vehicles often put out more torque and more horsepower when running on E85 instead of regular gasoline.

Does E85 burn faster than regular gas?

Due to ethanol’s lower energy content, FFVs operating on E85 get roughly 15% to 27% fewer miles per gallon than when operating on regular gasoline, depending on the ethanol content.

What is the advantage of E85?

According to the United States Environmental Protection Agency (EPA), E85 can provide important reductions in greenhouse gas (GHG) emissions as compared to petroleum-derived gasoline or lower volume ethanol blends. With a higher octane than gasoline, E85 can actually provide more horsepower.

What are the advantages and disadvantages of E85?

Because of E85s increased resistance to detonation, it allows for more power without the cost of expensive race fuels. Even at low power levels, E85 can also be a much safer fuel than normal pump gas. Much like methanol injection, the alcohol present in E85 is great for cooling down your incoming air/fuel charge.

Why does E85 get less mpg?

When you fill up with E85, you get fewer miles per gallon because ethanol contains less energy. So you have to fill up more frequently, which could wipe out your savings. The price of E85 would have to be more than 30% less per gallon than gasoline to be the cheaper fuel alternative for the Ford Focus.

Will E85 hurt my car?

Ethanol has a corrosive action on fuel-system components, magnesium, aluminium and rubber. Running E85 on older model engines without tuning and replacing some components will ruin the engine in short time. Replacing fuel hoses, fuel pumps, gaskets, seals, fuel filters, fuel injectors, throttle bodies, etc.

Does E85 Make your car faster?

E85 fuel can give you a significant boost in power and torque without breaking the bank for racing fuels. It has a base octane rating of 105 and has the bonus of added cooling properties that add even more knock resistance than racing fuels with the same rating.

Whats better E85 or 93 octane?

E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.

Is E85 going away?

As the new-vehicle market has shifted away from E85 compatibility, the Renewable Fuels Association has switched its focus to increasing the «regular gas» blend from 10 to 15 percent. The EPA has approved E15 for use in all vehicles produced since 2001, but not all manufacturers have blessed the fuel for that long.

Why is ethanol bad for engines?

Boatyards and marine engine dealers warn that gas blended with ethanol can cause motors to stop working, ruin rubber components in the engine’s fuel system and damage engine parts. The gas softens rubber components in the engine, some of which may dissolve and gum up the system.

How much HP can you gain from E85?

The more boost your running the more relative gain in power you will get. For example, on my pro charged TA with 7psi I only gained about 25 hp with e85 vs premium. When I ran 12 psi I gained about 55hp, again most of that is being able to run more aggressive timing without the risk of detention.

What happens if I use E85 in my car?

Putting E85 in a Gas Car

The check engine light will most likely illuminate, but you can top off the rest of your tank with regular gasoline and ride it out. A one-time mix-up with E85 gas shouldn’t cause any long-term damage.

Is E85 a racing fuel?

Sunoco E85-R is an unleaded racing fuel containing 85 volume % ethanol. Because it is highly oxygenated and requires increased fuel flow compared to conventional non-oxygenated fuels, consult with your fuel injection system or carburetor supplier for correct air/fuel ratio calibrations.
