is costco gas E90?

[artinist]

so i was getting gas from costco and saw a sticker that said this gas contains 10% ethanol, so does this mean its E90?

I would say its going to get crappy mpg and definetly not worth saving a few cents per gallon but would it be worth having a special tune for this fuel for power gain?

That mean its E10 lol. The Ethanol has to be 90% to be E90.

That mean its E10 lol. The Ethanol has to be 90% to be E90.

lol yup. But pretty much all gas station have about 10% ethanol and other mixed substances, like nitrogen, etc to keep the engine clean.

thanks for clarifying. my bad, I got the E10 and E90 backwards, lol. I thought the federal requirement was 5% ethanol. according to this site http://carwoo.com/blog/the-differenc...soline-brands/
the top tier gasses are closer to about 5% but cheaper gases like arco have higher ethanol content.

they didnt' have E85 back in 04 when I joined the forum nor in early 90s when we were street racing till 5am and since my car was always a daily driver, never looked into anything other than 91 octane until recently. that's why the post was in the form of a question

quit making excuses. you are now double failing. 1st you failed to correctly read/comprehend the sticker on the fuel pump, that by the way is on every fuel pump in cali. they ALL have 10% ethanol, as well as most of the country. and having 10% ethanol would not make it a "lower tier" fuel.
and now you go on to say thay did not have e85 back in the day when you were street racing.... ok well where you street racing? what were you driving back then? and what crew/shop did you run with? beacuse it sounds like you have been living under a rock since then..

the only information on the pumps at chevron is this although they probably don't have an updated sticker since Costco just recently got theirs

When I'm just doing the daily drive business, I do. In the gas I spend doing the daily drive and with Costco executive membership, my "rewards" check at the end of the year pays for another year of executive membership along with an extra $500+. I like being paid back for polluting the environment.
