88 Octane Gas in Maverick Hybrid?

[Old Man]

If we would all just read the manual or use Wikipedia, we wouldn' need this forum and we wouldn't get flamed.

Or we all would know how our truck works and the limitations.

Um, there is no such thing as 88 octane or E88. There is 87 octane which is regular gas and fine .
There is E85 which is 85% alcohol and used ONLY in flex fuel vehicles and is NOT ok to use.

I strongly suggest you both read your owner's manual in detail and spend some time on wikipedia or something educating yourself about gasoline.

Totally shooting from hip on that one...

Can I safely use 88 octane gas in my Maverick Hybrid? Often have lower prices for the E88 gas in my local area. Will using iteffect my hybrid engine?

No. E88 has too much ethanol. You can use regular 87 octane. It has 10% ethanol. E88 has 14-15% ethanol. The owners manual is adamant about this. There’s also E85, which is specifically blended for flex-fuel vehicles and has a much higher % of ethanol.

Manual lists 15% ethanol as the max both in general and specifically for hybrids, so it very much is allowed by Ford.

E15 or 88 "octane"/grade is okay.

E85 is not.

Fuel Quality - Selecting the Correct Fuel
SELECTING THE CORRECT FUEL

Your vehicle operates on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in high altitude areas, offer fuels posted as regular unleaded gasoline with an octane rating below 87. The use of these fuels could result in engine damage that will not be covered by the vehicle Warranty.
For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer. See Towing a Trailer.
Do not be concerned if the engine sometimes knocks lightly. However, if the engine knocks heavily while using fuel with the recommended octane rating, contact an authorized dealer to prevent any engine damage.
We recommend Top Tier detergent gasolines, where available to help minimize engine deposits and maintain optimal vehicle and engine performance.
For additional information, visit www.toptiergas.com.
Note: Use of any fuel for which the vehicle was not designed can impair the emission control system, cause loss of vehicle performance, and cause damage to the engine which may not be covered by the vehicle Warranty.
Do not use:

• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based additives, including manganese-based compounds.
• Fuels containing the octane booster additive, methylcyclopentadienyl manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is prohibited by law.

The use of fuels with metallic compounds such as methylcyclopentadienyl manganese tricarbonyl, which is a manganese-based fuel additive, will impair engine performance and affect the emission control system.

HYBRID ELECTRIC VEHICLE INFORMATION – FREQUENTLY ASKED QUESTIONS

What should I do if the vehicle runs out of fuel and the high voltage battery is out of charge?

• Refuel and start your vehicle normally. The engine will recharge the high voltage battery.

Why does the engine sometimes start at key-on?

• The vehicle's computer determines if an engine start is required at key-on. It starts the engine when necessary for cabin heating, windshield defrost, if the high voltage battery is low, or if the outside temperature is low.

Can I put E15 or E85 in my vehicle, and how will it affect my fuel economy?

• Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, but you may notice slightly reduced fuel economy because ethanol contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).

Why does it take a long time before the engine shuts down?

• There are several reasons the engine stays on for an extended amount of time when you first start it. One common reason is to make sure that the emissions components are warm enough to minimize tailpipe emission. As the climate gets cooler, the engine-on time is extended.

Why does my engine stay on when it is extremely cold outside?

• In order to make sure that the climate control system can begin heating the cabin or defrosting the windshield as soon as a driver requests it, the engine coolant temperature has to be kept sufficiently hot. Keeping the engine on is required to maintain the correct coolant temperature.

My bad. I originally read it as do not use 15%. Sorry.

 

[TheWizziard]

Yeah. Pumped the 85 in my Hyundai Accent ( in Wyoming) because it said Regular. After check engine light came on went straight to a Hyundai dealer.

Said they don't like 85, reset light and did next fill up go premium.

Just for clarification: You "pumped" E85 or 85 octane into your Hyundai?

 

[olderbudwiser]

Am waiting for those that live around 3500+ feet altitude with 86 octane pumps and those 5000+ feet 85 octane pumps to comment!

Yup spent lots of time between 5000-11,000 feet. First time I looked at gas pumps....it was WHAT !!

The MY23 manual is also available:

Is the MY23 manual available as a PDF somewhere?

Every pump at every station with more than 2 choices is a blending pump.

Additionally, there is leftover fuel in the hose from the previous pump, thereby further blending whatever your selection is, if it was different from the previous pumpers selection

This is a place in town that works on small engines and has no ethanol on all 3 grades. It's 5 miles out of my way so I only go there to get gas for my lawn mower and snowblower, maybe 3 times a year. Picture is from Google maps. Prices are usually ¢5 higher.

Well just found out the gas station I go to stopped selling 87 octane ethanol free gas. And now only sells premium ethanol free.

Ethanol is not junk.
Ethanol is not corrosive.
Ethanol can go in your body.
Ethanol is vodka.

Try putting gasoline in your body (no don't) just imagine the difference in "corrosion" and "poison".

Ethanol is a small, simple, clean molecule that when burned produces two clean molecules: water and carbon dioxide, the same "junk" you just exhaled.

If gasoline didn't exist (and one day it will run out) you'd ALL be calling ethanol a godsend.

Ethanol puts the premium in "premium".
You've all be duped. Brainwashed by big oil companies.

do you own any small engines? Why does everyone mechanically skilled use only ethanol free for small engine machines if ethonal doesn’t junk up the engine?

To add to the confusion, in Maryland and probably many other states as well, E85 Flex Fuel can be 51%-83% ethanol (USG DOE E85 flex fuel specification). E85R race fuel is the fixed blend 85% ethanol.
