Ethanol 101

Run your A on E85, and ethanol free fuel back to back, and you'll notice a seat of the pants difference. Go talk to the tuner guys that run E85 in their cars and make tons more power than on straight gas. Go play with alcohol / ethanol toys (sand cars, drag cars), and there are components designed to run on these fuels. Carb jets, injectors, pumps and other things are different for cars that are designed to run "flex" fuels, over cars that run straight gas.

I'm sure the dealer received their intel on pump failures tied to people running ethanol free fuel.

The diesel guys are going through the same thing with current emissions relating to sulfur content, DEF and other things.

It's completely believable.

The Chrysler Pacifica isn't a flex fuel vehicle. These cars are designed to run on fuels from a wide range of countries. A lot of EU countries are 5% ethanol, Japan's standard is 3% ethanol, and there's plenty of countries where E0 is still the standard.

Ethanol free fuel won't cause issues with automotive fuel system components designed to run on ethanol fuel. But ethanol fuel will cause problems on older automotive fuel system components that weren't designed to run ethanol.

The diesel fuel issue is related to modern diesel fuel's lower lubricity rating. Which is a completely separate issue from ethanol in gasoline

I thought it was implied that my comments were overly general regarding fuel issues in new vehicles, gas or diesel. Hence my use of "" around "flex" fuel; I wasn't calling the Pacifica a flex fuel vehicle. My high level comments were relative to gas and diesel fuels changing for emissions reasons (vapor, particulate, liquid), and how the change in the make up of fuels over the past couple of decades has drastically impacted the design of vehicles, to the point that using the old fuel formulations for a period of time will affect the performance and longevity of powertrain parts.

Ethanol free gas is not an "old formulation"

It's modern gas, that adheres to modern gasoline standards but minus the corn alcohol. It has the same detergent additives as E10 gasoline does. Any fuel system components designed to run E10 will not be affected by running name brand ethanol free gasoline.

I have ran E0 in every gasoline powered vehicle and engine I have ever owned. Like I said in my previous comment, the only difference between E0 and E10 is that E10 has 10% anhydrous ethanol blended into it. Otherwise, they are the same base gasoline, detergent, and additive mixture. Never once had an issue. I've found that all my cars run smoother, get consistently better MPG, and a small but noticeable increase in power.

You said in your previous post you have it delivered to your house. The only thing that could have caused your issues is either the tank you're storing it in is filled with debris or you've got very old gas sitting in the tank you store it in. That, or more likely IMO, the "tech" that "diagnosed" your car just made that up because he heard you put E0 in it and didn't feel like coming up with a proper answer as to why your fuel pump/filter kicked the bucket.

All the components of a fuel system designed to handle ethanol fuel are more robust than the components of older model cars not designed to handle ethanol. A fuel system designed to run ethanol will not be affected whatsoever by running pure gas. They are designed to handle the corrosive nature of ethanol.
