Question about e85 gas

I have personally done it but not in the Lexus. Are cars are modern enough to "work" with e85, now I didnt say they are modern enough to "RUN" on e85. I have tried it in my 335i and escalade, but the escalade was already flex fuel.
I can tell you on the BMW it was never straight e85 always mixed with 93/e85. Cant tell you if I felt anything different. Did it for about 5 months then was tired of going to the only gas station that would supply it. The escalade I swear i felt better power but needed refueling more often, sounded better too.
The real reason, we cant do it is because the fuel pump. Injectors(need larger ones) and of course the tune. Simply it was never designed to do it.

DON'T run e85 in your Lexus!! It'll drive like ******t. I tried some 91 octane and e85 mixture and at first the car pulled a lot harder as I was running the twin turbo setup at the time so my guess is increased air flow plus increased octane equals more power? Anyway... Long story short, the car started acting up badly. I would do 50-75% throttle pulls on the hwy and the car would bog out. It would feel like it was chocking. On a 335i you can easily do e85 mixtures with a tune and gain tons of power but that is not the case with the Lexus.

I have an '07 IS 250 and I run a 50/50 Premium/E85 mixture and have been for the past 30,000 miles. I have had no issues, and have actually maintained fuel mileage(due to our vehicles high compression ratio and ethanol's octane value) with this blend. E85 is 100+ octane. I increase the ethanol portion in the summertime. This also allows me to save money beings E85 is typically $1 cheaper than 91 octane premium. I'm a big believer in E85; it helps reduce our dependence on oil and it burns cleaner than gasoline. Most of what you hear about engine damage caused by ethanol is fabricated by the oil industry who is threatened by increased use of the fuel.
Short answer, give it a shot at a lighter blend and inch the blend up if you feel comfortable.
However, on pure E85 I did have the check engine light come on until I backed the blend down, due to fuel sensor readings I assume.

i use to think this too but its mostly the older vehicles that end up suffering from this. alot of the more modern cars the fuel lines can withstand. its the running e85 on a car thats not tuned for it or the fuel system to support is what kills cars.
yeah like gville said, trying to run E85 on a car not tuned for it or the fuel system to support it, thats what kills motors. alot of people dont understand you need 40% more e85 than you do 91 oct because it burns faster. hence why alot of modded cars have huge injectors with E85. without that, you run stupid lean and of course, the motor gives up the ghost
