Not sure about Monument, but the only place I knew of in the Springs was a place on 30th and Centennial. Unfortunately, they got bought by Phillips 66 and initially switched the 93 over to E85 (awesome!), but now they switched that to diesel

If you find a place, post it up please!

Will the E85 eat up the fuel lines or the lining in the fuel system?

No, you'll be fine Just mix in a little to prevent timing drops if you're worried.

I didn't realize you could get 93 in CO. I've only seen 91. Isn't Octane a function of atmospheric oxygen concentration? If you brought CO 91 down to sea level it would be 93, correct?

No that's not correct. You only need 91 octane to get the effect of 93 at sea level due to the reduced oxygen content, so they say. However, when we used to get 93, every modded car I owned was much happier on the 93 than it was/is on 91.

I live 5 minutes from the 30th/centennial station. Once I finally return to Colorado with the Flex Fuel kit, it's going to stink not having such close access to E85.

Nice - we must live very close to each other. What does your car look like? I want to make sure I don't line up next to you at a light and embarrass myself

Nice! We are basically twins then (black E90 LCI) but I'm not x-drive and have the style 287 wheels. You should plan on going to some of the bimmer burger nights and Bandimere/Pueblo MS - I bet that thing is a beast with x-drive and E85!

See you around town!

I'm running the jb4 map 2 which requires 93 octane and I'm running the 91 with 30% e85 and it works out perfectly! It's a fun, quick car for sure! 30% in these tanks are about 4.11 gallons. Hope this helps!

No, most gasoline can contain up to 10% of ethanol and this is disclosed on the pump. Also, the materials use in the fuel system for newer cars can withstand E85 without any issues. The stock fuel system is just not capable of delivering enough fuel to support E85 and higher horsepower, which is why it is recommended to upgrade the fuel system when using E85.

I put over 100K miles on a car with a custom dyno tune for 93 octane and only ever put 91 in it. As noted earlier, because of the altitude and the lower pressures that can be achieved even with turbos, you don't need the octane rating up here. The gas companies know that, and that's why the don't supply 93 up here very often. Once you drive back down towards sea level you will start to see 93 again, and once you do, just fill up with 93 while you are down there.
