GAS

Hi, Question! because we don't have 93 octane anymore but we have 92 and 100 what would be the ratio to come up with a 94 octain?math wizards help!!! Please. thanks

 

seems like about 9 gallons of 100 and the other 6 ish of 92

 

run 92 non oxy, that's kinda like running 93.

 

Here's a script I made to calculate percent mixes and the price per gallon for a target octane. There are 2 lines, one for mixing high octane fuel and the other for mixing toluene.

edit: to answer your question: about 25%

 

how do you know if it is non oxy?

 

it'll be marked on the pump (required by law)

 

I ran some tests last summer and decided 92 nonoxy is great. However, I recently switched FROM non-oxy BP 92 TO regular BP92 (with ethanol). I logged my timing advance before and after and AFTER switching to regular 92 I gained 3-6 degrees of timing advance.

My theory is that the non-oxy fuel I've been using is stale and has partly evaporated. This winter has been relatively snow-less so there hasn't been much non-oxy fuel purchased by snowmobilers. BTW, the non-oxy fuel I buy is from the BP off 494 and bass lake rd in Plymouth.


Long story short: I'm staying away from non-oxy until next summer

 

Did you just quick wip that up? you super smart

 

Not just now. I made it for a similar question a few months ago.
