Dirty looking gas, filter problems

We have only 2 places in the county that still sell real gas. Everything else has been E10 only for about a year and a half.
This week I saw 3 fuel filters being removed from FI cars and the gasoline coming out of the outlet side of the filters was grayish beige from suspended disolved yuck.
Even though this is passing through the filter, this has to be really good for injectors.

A month ago I redid a couple carbs that had this sandy looking residue coating the bottom of the float chambers.

I have seen some cars with see-through filters that the gasoline looked OK, so this might be a limited problem.

Anybody else experiencing dirty gasoline problems with E10 ?

alcohol attracts moisture
I already replaced my gas tank once with a stainless tank.

A friend of mine is an Honda mechanic at a dealership. They have had five cars come in with sludge buildup in the last few months.

There are 2 reasons why vehicles have come into my shop, from fuel related problems.

1. Dirty fuel filters, from buying the cheapest available, right after the fuel tanker filled the tank.

2. Vehicles requiring "mid" grade, or "premium" grade fuel. These fuels are not available at some of our local stations. Some station's have them, but those who do charge so much it is too expensive, for them to fuel up.This brings up the fact of old fuel being pumped, I have found lately.

with all due respect, I kinda have to chuckle. E10 has been used for at least 10 years. But, with the recent publicity of ethanol and the fact that most of the public has only known of its existence for the last 2 years, people blame a multitude of problems on E10 when in fact it has been shown to have NO effect at all on fuel systems other than reducing emissions.

Not busting chops, but I think there might be another more plausible explanation, like maybe a cruddy fuel tank.

Thank you Sir, but this is not california with its long ongoing smog problems,
and we just got E10.

To the best of my knowledge E10 was non-existent in most of the middle southern states, south of I 70..... and I traveled A LOT.
Illinois has had it for 5-6 years at about 40 % of the stations, mostly side by side with real gas, two 87 octane hoses, based on my travels there. Most of the 91+ was real gas, my Mark8 and TownCar use 91+.

A friend of mine is one of the last hold outs selling real gas, and he told me he could make another 12-16 cents per gallon if he converted, but his customer base wants real gas. He has 3-5 cars there continually all day long.

By the way, these states are mandatory labeling states and stations face a substantial fine for not labeling E10 as such. Besides, most people know what it smells like, and the crabb coming out of the bad filters is E10.

Ok, that's quite possible, but I still don't think its "crap" or causing any of your problems.

And I didn't always live in CA. I grew up in PA where it was just called "winter blended fuel." They didn't have to tell you what was in it and I guarantee most people didn't. I also lived in Miami, New Orleans, Austin and Montana... all of them used E10 back through the 80s at times and never called it anything but "oxygenated" or "winter" fuel.

I would look to real causes of the problem instead of blaming it on something you think is crap. Otherwise you might be chasing the symptoms for a long time.

Quite possible. Thank you.

One thing I asked on another thread was about test kits. Seems like the E10 sometimes gets MORE than 10 around here and there are lots of driveability problems. One supplier I know personally said he got a tanker load with one tank filled with E 40 by test. I also think there is a lot of suspended water.

About a month ago I was out of town and got a tank of EXXON 87 in my old TC and it pinged horribly. That car never pings. So quality is variable.

Fact remains that a lot of disolved gunk is getting through the filters. The source may never be determined without lab tests to see what it is.

Thanks again.
