Octane Gas Test - 661

[Deets066]

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

I'd run it too if that was the only e free

Until a few weeks ago I only ran vp 93 but when I switched to 50:1 is also switched to 89 and my saws seem happier.

Think it was due to less oil in your mix or change in octane?

I didn't see 110 in his test??

U wouldnt want to but we did see it on Chads dyno? Lower octane over average produced more?

Less oil produces more power?

Good stuff Mr. Redbull.

I'm thinking the 87 is of a lesser quality since the higher octane fuels in E free are sold there. Here, we can only get E free in 87.

 

[Ron660]

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.

Your octane tests with your ported 362 proved the highest octane was faster????

Both.

I'd love to see Redbull do that test. Same oil, same fuel, same saw, only different mix ratios. Like 50:1 vs 32:1. Most say more oil more power. I really don't know.

I dont either. Most articles say more oil produces more ring seal

 

[Mastermind]

Depends on the saw, and the tuner.

I believe it

I just dont believe my test was creditable . Too many variables in the wood and my cutting techniques at that time when I did that

And the oil

You did a good job I thought. At least it was consistent one way.

Thank goodness for mtronics. At least for all these tests.

 

[Keith Gandy]

And the oil

Surely some oils dont combust better and make more power?

Redbull's tests will hopefully solve that question with a comparison of timed cuts.

I'd like to see the rpm changes on a non mtronic saw
