It’s common to have issues with small gas motors. The margin in those is so tight that cost accounts search the world over for the cheapest parts that will do the job long enough to get out of the warranty. This is a rare case of replacement parts actually being better than factory originals.

 

in Jaguars? Nothing. Slightly cooler running. It won’t hurt the car.
In a car adjusted for ethanol? More power.

 

Nigel?
Alcohol makes more power than premium gasoline. The reason for that is alcohol has extra free oxygen molecules in it compared to gas.
Those extra free oxygen molecules allow more fuel to burn than gasoline can burn. More fuel consumed ( actually burned not sent out the exhaust as black smoke).

Now before you quote energy numbers. I’d like to remind you that diesel has more energy than gasoline.

In racing the amount of alcohol is carefully checked because of the added power.
Indy cars use 100% ethanol. NASCAR uses 15% alcohol . Drag racing, Land Speed record chasing all limit the amount of alcohol or move the car into the faster class

Alcohol burns cooler than gasoline and will clean up the deposits that gas leaves behind.
With regard to fuel hose. Jaguar has been selling cars in America since WW2. Wve used alcohol without problems since the 1980’s? ( I’ll look it up ). Jaguar has had 2 recalls regarding their fuel hose . Read John Egan’s SAVING JAGUAR for confirmation.

As far as economical. The price of Ethanol lowers the cost of Fuel. By using ethanol they can get the required octane numbers from more of that barrel of crude oil.

 

America has been using it since the 1980’s ( yes in our Jaguars). Without any of the problems that the scare mongers are claiming.
They are confusing Ethanol with Methanol. While they are both alcohol.
Ethanol does good things for our Jaguars
Methanol does all the bad things people claim.

 

Dude this thread hadn't had a reply since 2017, half the people you're replying to probably aren't on the forum any more...

 

IT’S not totally about being green. It’s also about sending your money out of the country.
Ethanol can be made from a big variety of things Corn, Switch Grass, any grain or fruit. Etc.
Typically that is locally grown. While oil is typically imported.
The use of ETHANOL extends the amount of gas the refinery is able to get out of a barrel of oil.
Also Ethanol makes more power than gasoline does.
Ethanol does three things. It provides more free oxygen molecules. Which means it can burn more of the energy in the fuel than gasoline. That’s where the power gain comes from. *
It’s also a cooling agent. Put some alcohol on your skin and feel how cool it is when it evaporites. Third it’s a wonderful cleaning agent. Gas leaves dirty deposits. Especially on the back side of the intake valve. Which reduces airflow into the cylinder costing power and fuel mileage. It also clogs up the fuel injects eventually and well as foul spark plugs sooner.

You can prove that to yourself by putting a small amount of gasoline into a sturdy glass container.
Carefully light the gasoline. And look how dirty the glass is. Notice too the dark smoke emitted as it burns.
Now clean the glass container back up. Put in the same amount of alcohol & carefully light it.
Notice the flame is almost invisible with no smoke.
Look at how clean alcohol burns compared to gasoline.
One final point. If you tried to put out the gas fire with water, because water floats on top of gas
the flame is spread.
Whereas with alcohol water is absorbed by alcohol and quickly goes out.
