The Citgo in Orlando, FL, off of I4 exit 81C, tests 87½% ethanol as of a week ago.
I don't drive my Evo much nowadays, and I still have the same jugs of E85 since 9 months ago. I tested the fuel again and it appears the ethanol content went up about an estimated 2.5% compared to when it was fresh on day 1
So I repeated the test 2 more times with the same result. Not complaining
I'm gonna store a cup of this ethanol and check again in a year. This is interesting. Does anyone have an explanation for this?
I follow Propel on FB & they just posted an update on their remodeling of the pump shrouds. Here was my response & their reply
Thats good info, it further underscores what i said in post #75. If they lower the Ethanol content in the blend they will lose all their California tax incentives, which is probably the only thing keeping E85 production profitable here.
Nothing bothers me more than when ppl call E85 "Flex Fuel". The term Flex Fuel means that no matter the ethanol content, your vehicles ECU will adjust the maps accordingly to provide the best performance on that mixture. Ethanol is NOT Flex Fuel...Ethanol is an ALTERNATIVE Fuel. Flex Fuel is an Adjective as opposed to a Noun haha
E54 is obviously a 50/50 mix and quite honestly, very close to being pointless to use! anything under about E35 is an Inefficient mixture of Ethanol/Petrol. E15, which most station use these days, is the close to the maximum amount of Ethanol you can use w/o leaning the AFR out...ive used 20% before w/o any problems but once i hit the 30% mark, the mixture was starting to be a little too lean and causing occasional backfires. You wont see any performance improvements until around E50, and you really cant start advancing the Ign Timing until about E60. It wasnt until E70 to where i started to make significant gains, and from there up is where you start to have fun!
Point is, there is no Point in using E54! LoL
We have only 2 gas stations in NJ that I know of with E85. The most popular being at Newark Airport. It's a shame because it truly is a great fuel... It's all politics.
Here's a test of a 3yr old sample of E85 I have in a container jug in my garage. The same gas is still in my Evo, which I fired up after letting it sit for a while. It sputtered on a lean condition for about 5 minutes before the air/fuel ratio stabilized back to stoichiometric ratio of 14.7. I figured the fuel in the lines got bad, but not the tank.
