So, Bolens 1000, what your saying is, that regular gasoline, 87 octane is lower than 87 because of the ethanol. ??

Noel

 

From what I heard the ethanol has a lower energy output than the regular fuel requiring you to burn more than regular gas in an older engine.

Bro you are full of it. My advice if you have no clue what you're talking about you should not be posting.

The guys I know who go to the service seminars for all the major engine manufactures tell me this, I guess they are lying to me!

That's my understanding too.  The energy content of ethanol is lower than gasoline, so you get less mpg.

The octane rating of a fuel is a measurement of it's resistance to spontaneous ignition under high temperatures and pressures.  It's often presumed to be higher energy because high performance engines sometimes require higher octane fuel.  What actually happens is the engine designer uses higher pressures (compression) to boost performance.  Higher octane fuel is then required to prevent pre-ignition.

Correct, MiCarl. This is also my understanding of octane rating.

So energy output or content means btu's per a certain amount of fuel. In other words, so many btu's, per gallon, per type of fuel.

Correct, as I stated before!

I am confused as to which part of Bolens 1000's post you are disagreeing with. The first paragraph is correct, when unleaded fuel was introduced valves/seats had to be made differently.

The second paragraph is also correct, a cheap HF infared thermometer will show you that. Easy test, run 10% ethanol, check the head temp. Drain gas, use non-eth fuel and re-check.
Ethanol burns hotter than gasoline.
Ethanol has less btu's per gallon. That's the easiest to check. If you have or know someone with a flex fuel vehicle, ask them their mpg using both fuels. Normally, E85 gets 25% less mpg than E10. My FIL has a '07 1500. 19-21 mpg on E10, 14-16 on E85.
Ethanol pulls moisture from the surrounding air. It tarnishes and leaves deposits in carbs if left idle in as little as 3 weeks in some environments.

His last paragraph may be open to interpretation. If going by pollutants released per gallon burned, his statement is false. It would be true if you were going by emissions per btu.
Or maybe he was just commenting towards the well documented fact that it takes 1.2 - 1.3 gallons of fuel to make a gallon of ethanol.

If you knew Brian at all, you would be very well aware of the fact that he knows small engines inside and out. Rather passionate about them, as a matter of fact.

I was waiting to read the "stupid son of a B-iotc*" statement! Lol

Good call, if ethanol IS "SO" good, it would be everywhere!

Put that in ur Briggs N light it rippinryno ;)

Im done with this nonsense...

In your previous post, you said you were done with this nonsense. Now you're the thread's jury? Good grief, make a choice and stick with it!

If I was the texting type the LOL would follow the above statement. But I am not.

LOL.

I do what works for me --> Post #2. I assume each does his own. as Regular and leaded gas is available for a price. I deal with the E-10 as I can.

Mixture as stated in post #2, and replace the fuel lines and filters around 3 years.
