Can I put regular gasoline in my flex fuel ford car

SAMETHING

Regular gasoline, E-10 all the way up to E-85 (85% ethanol). The higher the E number you use the larger the drop in fuel mileage. Just DO NOT put diesel in it.

All correct, just don't put regular leaded gas in./ if there is any around anymore.

Aviation gas still has some lead.

Ok I was wondering because my truck says flexfuel but I been putting in 91 in it

That is fine. Flex fuel system means you can run the E85 corn gas and or the regular unleaded gas. 91 or 87 octane is fine.

i have 2006 impala LS. it is also flex fuel. so there is not any close station of E85. can i also use 87 UNleaded gas?

Yes you can umair007, I have 2010 Impala flex fuel. I run the regular 87 octane gas in it.

The regular unleaded 87 octane gas is even better than the E85 corn gas. The E85 is just an alternative fuel.

I have a 2015 Ford Focus Hagback and it seems to be drinking my gas when I use 87 unleaded do I need to start using mid grade gas or is something wrong with my car ?

CR1D may need to change the air filter. Also make sure you have the proper air pressure in your tires, and keep your foot out of the gas pedal...

Is there a problem starting a flex fuel engine and turn it on and off in a short time causing it to run bad?

No there should not be any problem starting. You must have some problems starting to arise. If the check engine light is on go to a auto parts store and have the vehicle scanned for trouble codes. Write them down for diagnostics.

Do general maintenance on it, change air filters, oil, check tranny fluid ( maybe needs a change), change spark plugs. I dont know about newer trucks bit older trucks get about 15-20mpg. If its flex fuel try putting in either 88 or higher. I have a flex-fuel Chrysler 200that was inly getting 22 average mpg. So I did general maintenance, and started using 88 (aka e15) and gas mileage out of town has improved. If it still does not improve, check for even the smallest of leaks.

Also check for vapour leaks. Any vapor leakage would also drop your mpg.

I have a 2008 Ford Crown Victoria can I switch back- and-forth from 85 to 87

I bought a 2013 F150 5.0 V8 flex fuel. Does the E85 have any bad effects on the engine over time?

Can I put regular gasoline on my Ford Escape it’s a flex fuel

Yes you can put regular gas in a flexfuel vehicle. Referring to the owner's manual would yield that information.

I have a 2017 Dodge Grand Caravan that has started having all kinds of starting issues lately in this cold weather. At 25k miles, I took it into dealer to fix. Finally after bringing it in multiple different times for them to try stuff to fix it, they checked the fuel. Turns out, according to this Chrysler dealer, mixing e85 and unleaded is causing particles to show up in my gas tank, or debris in the gas. It ran great all summer with my mixing regular and e85 all the time but once it got cold (10 F or lower) I started getting these sputter starts where the engine had to sputter and sputter to finally get started. They recommended i use up the whole tank before I switch to regular or to e85....not to mix. Funny how my last vehicle, a Chevy Uplander had no problems running both kinds of gas all mixed up . I ran that vehicle to 200k miles before trading it in. Thoughts anyone?

From what I understand, that doesn't make a lot of sense. I would talk to another dealership.

Daniel - The Chrysler 3.6 honestly just doesn't handle E85 at cold temperatures well. They didn't get the mapping right - and maybe, someday, they will own up to it. It's been a problem with that engine since the day they rolled the first one off the line.

I have a 2012 Jeep Grand Cherokee the manual says and the gas cap says to use E85 if I use regular gas will it mess my car up

To the guy above. That is totally wrong. Your Jeep may be able to run on E85 but it will run better on real gasoline.

2015 Ram 1500 3.6L Flex Fuel, I have experimented using E85, while towing and not. I ran I full tank of 91 octane gasoline got 15.5 mpgs. The next tank all while driving cross country, filled full tank of E85, got 18 mpgs average the full tank. This was towing same trailer, on a steeper roads too. This plus the fact that all the people at the local race track have converted their race cars to Ethanol. I'm sold, better mileage, half the price! Plus reading specs on my truck, it's fuel system components are better upgraded parts to withstand the Ethanol, so hopefully longer life on the engine. The truck runs great, and it's a V6 that thinks it's a V8!!

E85 will NOT yield better fuel economy. Comparing straight gasoline to E-85, E85 has a much higher octane rating, but yields less energy than gasoline.

Good morning Bob...

i have 2014 focus that is flex fuel, with the 2.o liter engine, how will it run with it, and can i switch back to gas if i dont like the way it runs. lee

Is it a waste of money to use premium or plus gas on a Ford flex fuel or would the vehicle run better for the long run ?

Yes it is a waste of money.

E85 in cold weather will give you issues with your cold crank start ups. Use a lesser amount of ethanol if there’s one around you. Usually companies will do it depending if it’s summer or winter. But if you can’t find a less ethanol alternative, just use regular gas. Issue will go away.
