Mixing Methanol and Gas
I have 2 questions about running 2 different types of fuel:
1)
I started to run Ethanol in my car and have nothing but good things to say about it. Its cheaper and has a 100-105 octane rating. It has a blend of 15% gas in it, im assuming to help keep things from corroding? I have ran 2 tanks so far and made the necessary fuel adjustments. Will I have problems with my aluminum cell and lines with ethanol?
2)
I started thinking. I should have the fuel system to support a methanol mix as far as volume. I was thinking of taking mixing methanol and regular gas and put it in my race tank(plastic). My questions are how well do they mix if they will? Will the gas mixture based on a percentage keep things from corroding?
Im thinking by doing this I want gain from the benifits of methanol and distort the negitives if everything works...What are your thoughts

That sounds like the E85 I was asking about in this thread.

1) As mentioned above, that sounds like E85
2) Methanol and Ethanol are 2 different types of alcohol. Methanol is the main ingredient of gas line antifreeze. Normally if you're trying to bring down emissions for an emission test, you can put a quart/liter per tankfull. You can't run a huge percentage of methanol without doing a big fuel system change. My race car runs 100% methanol. I burn about twice as much methanol as I would gasoline. To get that much fuel into the engine everything needs to be bigger, not just the jets. Methanol is also corrosive to fuel systems and I need to put a container of lubricant in every barrel of fuel I buy. Methanol exhaust fumes are formaldehyde which are poisonous.
Stick with the E85 blends. If using methanol was that simple to use in a daily driver, it would have been used already. Ethanol blends have been around for years. The E85 is just new.

Re: Mixing Methanol and Gas
I'll tell you what...
I have already decided to build my motor as an E85 motor.
I wasn't going to a Methanol motor, for all the reasons everyone is familiar with, but after discovering this E85 stuff...

The following is excerpted from this link.
E-Blend, however, does not have the same compatibility characteristics of conventional fuels when it comes to storage and dispensing. Soft metals such as zinc, brass or aluminum, which are commonly found in conventional fuel storage and dispensing systems, are not compatible with E85. Steel tanks and piping must be UL Marked or certified by the manufacturer for use with E-Blend Fuels.
Some nonmetallic materials may also degrade when in contact with ethanol such as natural rubber, polyurethane, adhesives (used in older fiberglass piping), certain elastomers and polymers used in flex piping, bushings, gaskets, meters, filters, and materials made of cork. In order to store and dispense E-Blend fuel, fiberglass and steel UST systems/components must be listed by UL Marked or certified by the manufacturer for use with E-Blend fuels.
