Octane Gas Test - 661

[Redbull661]

- all e free gas from 3 different gas stations
- all mixed with 32:1
- new .404 RS stihl chains for each test
- no reset performed. I ran some other tests previously and did reset. After a lot of testing, I just don't think a fuel or oil or oil ratio change requires it. I actually think it's counter productive to the test to do it.
- bought all this gas on the same day with-in a window of 1.5hrs.

Can you get all those e free gasses in Wisconsin? Is it the Fleet Farm in Hudson?

In Minnesota, by law, they are only supposed to sell 91 octane e free, not other octanes. Looks like Fleet Farm 89 e free is the way to go.

 

[Keith Gandy]

Id say its all over the place because of different qualities of fuel

 

[Keith Gandy]

Id be interested in pump vs canned fuel

 

[Keith Gandy]

Did the 89 have more torque when u say it ran better?

 

[Keith Gandy]

I don't know about more torque. It's the only saw I run really so I've got used to how it acts. Usually I run 91 bp. It was just running better with the 89 fleet farm. Not sure how to describe it. I was actually thinking 87 would run the best.

I figured it would too but it may be totally different if u ran it again? None was enough to be a big winner though . 87 vs 110 would be a good test also

cenex 87 times are legit. They coincide with previous tests where I was running 87 cenex.

Fleet Farm 89 times are legit as well as they also coincide with other tests I was doing. As do the temps.

why bp91 & ff91 ran hotter than cenex92 ya got me. Curious what ya guys think.

Great. Just what I guessed....91. Well the 89 same but faster than 87.

Hold on! U arent gonna average thoso 2nd set of cuts? 89 is a clear .6 seconds faster!!! Lol!!!

Didn't you guess 87??

 

[Keith Gandy]

Didn't you guess 87??

Lol! Sure wouldnt 110 . Lower octane produces more power.

 

[Deets066]

87 was faster than 92

Didn't you guess 93 Ron?

 

[Ron660]

Lol! Sure wouldnt 110 . Lower octane produces more power.

91 is less octane than 87?

 

[Ron660]

87 was faster than 92

Didn't you guess 93 Ron?

It wasn't 87. My memory is bad. That's what my wife says too.

 

[Ron660]

I'm using the cheapest non-E I can find.

 

[Deets066]

91 is usually the only e free around here

 

[Keith Gandy]

91 is less octane than 87?

Far cry from 110. Might not have been 87 but it was close to it and clearly the higher octanes fall off as u go higher.

 

[Keith Gandy]

91 is usually the only e free around here

I cant get anything over 87 efree now . Use to have 91 and 87 but they quit carrying it

 

[Ron660]

91 is usually the only e free around here

93 non-E is the closest to me. A few weeks ago it was $2.64/gallon.

I didn't see 110 in his test??
