octane in fuel
At my local petrol station i can get several differant fuels.
i can get standard unleaded at 95 ron i can get super unleaded at 98 ron and shell optimax at over 99 ron which is the best fuel to run on a turboed B16? |
Re:octane in fuel
The higher the octane the better.This will help prevent detonnation since high octane gas is less likely to pre-ignite.99 octane?Where do you live?

Re:octane in fuel
add toulene
Formula #1 - Toluene R+M/2.........114 Cost...........$2.50/gal Mixtures with 92 Octane Premium 10%...........94.2 Octane 20%...........96.4 Octane 30%...........98.6 Octane Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores. Formula #2 - Xylene R+M/2.........117 Cost...........$2.75/gal Mixtures with 92 Octane Premium 10%...........94.5 Octane 20%...........97.0 Octane 30%...........99.5 Octane Notes: Similar to Toluene. 12-16 ounces will only raise octane 2-3 *points*, i.e. from 92 to 92.3. Usually mixed with Toluene and advertised as *race formula*. Formula #3 - Methyl-tertiary-butyl-ether (MTBE) R+M/2.........118 Cost...........$3.50/gal Mixtures with 92 Octane Premium 10%...........94.6 Octane 20%...........97.2 Octane 30%...........99.8 Octane Notes: Oxygenate. Very common in octane booster products. Has lower BTU content than toluene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy. Formula #4 - Methanol or Ethanol R+M/2.........101 Cost...........$0.60 - $1.75/gal Mixtures with 92 Octane Premium 10%...........94.3 Octane (Methanol) 10%...........94.7 Octane (Ethanol) 20%...........Not Recommended Notes: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combine with water. Formula #5 - Isopropyl Alcohol and Tertiary Butyl Alcohol R+M/2.........101 Cost...........$0.60-$1.50/gal Mixtures with 92 Octane Premium 10%...........94.5 Octane 20%...........Not Recommended 30%...........Not Recommended Notes: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol. |

IS THIS REALLY SAFE in the long run for your fuel lines and motor? LEMME KNOW GUYS, i have been considering this for a while now. |
Re:octane in fuel
yep its safe. toulene is the main ingredient in the gasoline to create octane..
alot of snowmobilers use toulene to get 100 octane without it being leaded.. its safe dont worry. but just dont mix it wrong.. only 30% no more. |
Re:octane in fuel
Just remember that those percentages given by Shortyz are by volume.So if you have a 10 gallon tank to get 94octane you have to first only have 9 gallons of gas in it or the toulene wont fit ::)But to 9 gallons of gas to be 94 octane you would ad 9 tehths of 1 gallon of toulene.
So my point is that the % is of the volume of gas in your gas tank. |

So my point is that the % is of the volume of gas in your gas tank. so basically 30% mix is 7gal gas, 3 gal toulene. so how many of YOU, not somebody else, use this ---- in your cars? just curious. |
