info on E 85 tune

[buschris]

I'm curious about this too, since we have E85 for just at a dollar a gallon

Jack,
Ya beat me to it as usual.. but you are correct about octane ratings. it is purely for preventing pre-detonation of the fuel. END OF STORY! it doesn't do anything else. Here is Colorado our regular gas is 85 not 87 octane but can be used as 87 becase when you are a mile or more high in altitude the oxygen in the air is less so that is a natural inhibitor of combustion.. E85 requires about 15 to 20% more fuel to go the same distance or produce the same power. and thus you will see your E85 mpg drop by 15 to 20 % so unless the gas is more than 15% to 20% Less expensive that regular gas you are not saving anything... locally to me its only about 20 to 40 cents a gallon cheaper than regular gas

Thank you southpaw - nice addition from you to the octane and E85 story too!

Here's a link for nationwide and state-by-state percentage spread in prices between gas and E85:

http://e85prices.com/


Nationwide, there's an overall 12% difference right now. A few states have as much as a 16% difference and some (AZ, UT), show E85 is more expensive than gas.


I'll save my opinions about E85 for another forum section...

Good link, Sburn! I have not noticed E85 for sale here in Tucson at all. I KNOW what my opinion of E85 is (and it's not good - I ranted on it in a couple of other threads, here, and on f150Online).

I'll be interested to see your opinion!

All I am going to say is that Jack and I agree on this point.

Good post Jack, Sburn, and Soutthpaw.

Jack, Bill and I have already some threads and or posts on this subject.
Sorry I can't post links to them.

In Utah, CNG is actually pretty popular as its about 75 cents a GGE (gasoline gallon equivalent)
compare to $2.19 a GGE here in CO when I had my CNG crown vic. if we had a decent infrastructure for CNG fueling stations nationwide it would be a great choice for alternative fuel.. Along with the various new Biodiesel sources like algae, synthetic engineered bacteria diesel etc..
Natural Gas is the product used to make hydrogen for hydrogen fuel cells... why add the extra step? We have the fuel and technology to run CNG now.

Good, southpaw - I do think CNG is a viable alternative. We have a lot of CNG vehicles on the road here in Tucson, most notably, city buses. As you say though, the infrastructure is the BIG problem. If I put a CNG tank in my truck and then travel up to Mt. Graham, I'd like to think I can refill the tank in Wilcox, when I come back down off the mountain.

I think this is where Obama should have taken his infastructure improvement package... but doesn't seem like it is going to be in there.... there are some real benefits ot CNG. one is that after 25K miles the oil looks as clean as the day you put it in the engine because there is no by-products of combustion... 25 or 30K mile oil changes... I can't help but think the oil companies have something to do with the lack of CNG popularity
Los Angeles CA has the largest Clean Air mass transit system in the nation. just more useless info.
I also remember reading that for the cost to build 1 mile of 6 lane Freeway you could build 76 miles of Monorail... I am a big supporter of building monorail systems too... I think they could solve a lot of mass transit issues but Politics and special interest money keep it from happening... Like the recent attempt to make the funding of a monorail/train from Disneyland to Las Vegas look like a bad ides.... If you have ever driven on I15 from CA to LV on any Given Friday or Sunday you would see how many people would benefit and how much emissions it would reduce... as well as good for the economy of both states...
