10% Ethanol Safe?
Got some gas the other day,after I filled the car I noticed a sign that said "May contain 10% Ethanol". Is it safe for the Is350? Thanks.

"Lexus allows the use of oxygenate blended gasoline where the oxygenate content is up to 10% ethanol. Lexus recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions, and improve air quality."

Keep in mind though, your mileage will be less. Ethanol does not have the same specific heat as gasoline (few fuels do), so your mileage will drop slightly.

I was reading about it on the Subaru boards people were using it even in the 1999 models. It did however throw a check engine light for fuel trim code for runing lean but ran just fine. Some different mixes provided better results without any check engine, and you needed some things to run it without any problems.
Probably doesn't totally apply to our cars but its interesting to read.

MON 92 / 89 / 80 - 90
Heat of Vaporisation (MJ/kg) 1.154 / 0.913 / 0.3044
Nett Heating Value (MJ/kg) 19.95 / 26.68 / 42 - 44
Vapour Pressure @ 38C (kPa) 31.9 / 16.0 / 48 - 108
Flame Temperature ( C ) 1870 / 1920 / 2030
Stoich. Flame Speed. ( m/s ) 0.43 / - / 0.34
Minimum Ignition Energy ( mJ ) 0.14 / - / 0.29
Lower Flammable Limit ( vol% ) 6.7 / 3.3 / 1.3
Upper Flammable Limit ( vol% ) 36.0 / 19.0 / 7.1
Autoignition Temperature ( C ) 460 / 360 / 260 - 460

Just to make this very clear, a common misconceptioin. Ethanol is simply grain alcohol (the stuff that gets you drunk) is NOT corrosive to rubbers and the such. It will NOT hurt a conventional automobile.
Methanol on the other hand is corrosive, and typically is not used except in a race car application where every time the car is done being used the fuel system is "flushed" with normal gasoline, to prevent the corrosion pf aluminum and rubber fittings etc.

While aviation fuel is call 100LL (100 octane Low Lead), it's still higher lead than the old leaded mogas so it will kill your catalytic converter with one tank full. Besides, you don't need higher octane, the engine computer prevents pre-ignition anyway.
