E85 can be perfect for the high horsepower or high compression build, as long as it is readily available in your area. 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. What cars can run e85? What Vehicles Can Use E85?
The brand with the most Efriendly vehicles on the market is General Motors. Does e85 Make your car faster? E85 allows your to run more timing, which yields more power gains. To reap the full power benefits of ethanol based fuels you'll need to increase fuel flow. Despite having a higher octane rating, E85 has a lower overall energy density than pure pump fuel.
How do you make e85 fuel? This is the standard ratio used to turn pure ethanol into a reliable fuel source. Mix the two liquids in a clean gas can or similar container, and make sure you seal the container afterwards. What is the octane rating of e85?
Do flex fuel engines last longer? Flex fuel gas mileage tends to be somewhat less than standard gasoline mileage. However, since ethanol has at best, an 85 percent energy density, when compared to gasoline, you can see that ethanol does not get better gas mileage. Joined Mar 8, Messages 13 Location wisconsin. My first flex fuel vehicle.
SM Full Member. You can. However, you might want to run a few tanks of regular gas through it first to establish a baseline on your average fuel economy. When you switch to E85, be prepared for a BIG drop in fuel economy. Ya gotta pay to be green. SabreXray SM It seems to be working out fine.
The Av's computer will do the rest!! Aussie Red SM Hard to always find E Joined Oct 3, Messages Location Georgia. Aussie Red said:. I think GM recommends burning at least 7 gallons of the existing fuel in the tank prior to switching to the other.
That shouldn't be a big deal in the AV - just accelerate hard from a stoplight and watch the needle drop! Maybe he was wrong? Rocky07 Full Member. The computer will adjust to any percentage. I use both fossil and E and re-fill at all ranges of the gas guage. PM He was wrong, although I tend to do that anyway. Rocky07 said:. Mix it how ever you want. The only problem is that non flex-fuel vehicles don't have the sensors necessary to detect ethanol content.
They also don't have the control software to manage the air fuel mixture properly. It could also cause major damage, and using E85 in vehicles not equipped for E85 usually voids your warranty. Flex- fuel vehicles can run on either gasoline or E85 , a fuel that's 85 percent ethanol, an alcohol made from fermented plant material in the U.
To accept E85 , some parts of the engine have to made from materials resistant to the corrosion ethanol can cause. Not all Dodge Grand Caravans are flex- fuel vehicles. If your gas cap is yellow, then your vehicle can run on regular gasoline or E85 fuel , which is a blend of 85 percent ethanol and 15 percent gasoline. Yes you can , but it's a waste of money.
Run the lowest octane that your car will run optimally. Many cars today have knock sensors so running regular gas in a car that recommends premium is ok, with reduced performance. Compression is one indication of whether or not you require premium. Flex - fuel Vehicles. Except for a few engine and fuel system modifications, they are identical to gasoline-only models. If you put mid-grade gas in your car, it's actually cheaper to pump in a mixture of premium and regular to get the same octane level.
It's perfectly fine to combine different octane levels of gas , as long as they're both unleaded. Neither do they vary horsepower ratings for E85 ethanol flex-fuel engines.
E85 ethanol has an octane rating of , versus for gasoline, but manufacturers do not tune E85 ethanol-capable engines for higher performance than their gas-only counterparts. E15 was approved for use in model year and newer cars, light-duty trucks, medium-duty passenger vehicles SUVs , and all flex-fuel vehicles FFVs by the U. Write Your Answer.
