Isopropyl Alcohol
 

with ethanol(E10) almost fully integrated into our filling stations, i keep hearing about isopropyl alcohol. can it be used as a safe additive(fuel cleaner) and perhaps increase FE?

i did have great increases in FE w/ acetone, but now to debate its results is a moot point since ethanol negates its affect. i did confirm that in my testing as well.

so, is isopropyl safe enough to test? might it have a positive affect on FE? if so, why would E10 not keep fuel systems clean and increase instead of decrease FE?

Absorbs 5 times more water than regular gas-line antifreeze. Recommended for fuel-injection engines. Safe for catalytic converters and oxygen sensors. Use in all engines including 2-cycle or diesel engines.

Does that sound safe? MSDS linked on that page will tell you it's 99% isopropanol (another name for isopropyl alcohol) and I'd put $1 on the 1% proprietary additive being water :D

Edit: Oh by the way, grocery/drug store stuff don't go below 70% concentration. Holds it's water in solution in gasoline down to about 68% IIRC, if you wanna use it in winter, go up to the 91 or 99% for best antifreeze benefits.

I've heard it mentioned that it is a good idea to use something like MMOil in the gas also to lube the fuel pump.

Also...I intend to test 24 oz canola and 3 oz 91% iso per 10 gallons...a promising combo where the canola is supposed to burn and lube and the iso boosts power some.

I'm afraid it might smoke a lot though.

I tested 4-5 oz 91% iso and it gave more power for sure.

You're going to put canola into a gasoline engine? I'm rather skeptical...

There's some theory about it making metallic soap surface lubes and bonded polymer coatings, personally, I call that sludge :D

I've added 4oz of 91% iso alcohol and 4oz of used motor oil into a push lawnmower tank of gas with minimal smoke. 8oz of oil did cause smoke but still ran.

Don't foul up your cat with all that extra oil added - I would think that caster oil would be better since it is a good two stroke lube.

24 ounces of canola per 10 gallons? That's nutty. What's the science behind this? What's it supposed to do? It's certainly more oil than you'd ad for any upper cylinder lube.

Exactly, I can see using a couple or three ounces, but unless you're trying to "cure" an accidental tankfull of E85 in a non-flexfuel vehicle, I'd say that much is overkill and may gunk up your motor quickly. On the metal soap and polymer coating thing, that seems like something you want as an occasional treament, not being made in dozen ounce quantities for every tankfull.

The info I'm referencing is here:

"I'm currently doing 1qt to a daytona tank (13 or 14 gallons). Plus Acetone at 3oz per 10gal.

I used just soy veggy oil last 3 times to brake the myth about canola oil. Paid 1.25 a qt at Biglotts.

Filled up 3 days ago and we had 40's at night and 70's to low 80's during the day and my tank average display is showing 30.1mpg. It is normally at least 4mpg off from the actual.

Other sucesses here at work:

Ford festiva was 38 now 44

Late Jeep wrangler 2.5L was 15 to 16, now 18 to 20."


These last two are 38 % and 22% mpg gains. The iso would maybe help offset the ethanol issue. I still say SMOKE though. Good idea to pull a plug and check for oil?

Final analysis? use DUE DILIGENCE...some of the stuff I post is hypothetical.
