But it's not for e85



But on all seriousness, I need plastic. Me clumsy.

I park my car for a month or so sometimes with E85, no issues.

I got an update on my car Kaj, 8 months in the shop without a start and my eca still says e87 after sitting that long so it should be ok.

As an FYI, the way the sensor works is that it measures gasoline characteristics, not actual ethanol. (I know, it seems counterintuitive)

You could have 87% water and 13% gasoline and it would read E87.

So basically what I am saying is that the sensor is not a good indicator of showing you if the ethanol is contaminated with moisture or not.

If that is the case then why do they sell it as an analyzer? And why would it read different between fuels? I understand what your saying but it doesn't make since to me being if that was the way it worked then it would read high all the time no matter what type of fuel was in it.

Sweet, thank you! Assume all other factors are more or less the same, that makes me feel warm and fuzzy
. I ran through the 85 and have been on pump one tank, e85, now back to pump. No problems to report.

cool thanks for the vids i look forward to watching them.

The sensor measures Dielectric Constant. The dielectric constant of Gas is about 2.0, Water is 80.4 and Ethanol is 24.3. These values change a little depending on temperature.

If you add water, the meter will read higher. The engine will also be less likely to detonate. The water increases the octane rating of the cylinder contents as water does not combust, and therefore does not detonate. If the water content gets high enough, it will phase separate and then you will have a water ethanol mixture in the bottom of your tank and a gasoline mixture in the top. Burning the water/ethanol mixture may keep your car from running...it may not combust well.. Burning the gasoline may make your car detonate due to the lack of octane. If you are running E85 it takes a lot of water to get phase separation.

One thing to note, if you fill up and months later your meter shows an increased reading, your fuel has absorbed water, raising the Dielectric Constant of the fuel mixture.

Great info and thank you for the link good stuff

Here is an interesting article on "water uptake" for E10 blends.
