 Ethanol killed fuel pump! (?)



At the end of last week my 2002 325 wouldn't start. I had it towed into the the local BMW dealer (Boston, US area) today and they tell me that the fuel pump needs to be replaced. They also say they've replaced about 50 fuel pumps in the past week or so and that it's caused by gasoline blends with more than 10% ethanol.

I didn't fill up with E85 and I know that blends are not supposed to exceed 10% ethanol, especially if that's what it says right on the pump. But the dealer thinks that off-brand stations are selling blends with >10% ethanol in order to lower their costs.

I guess that's possible and I'll be probably buy branded gasoline from now on. But if an off-brand station was "cheating" just how much does it take to f*#k up your fuel pump? That I can see this problem happening again and again is both scary and frustrating.

Anyone else heard of this?

I could be wrong... but I thought I read somewhere that ethanol was more expensive to produce than fossil fuels.

This also presupposes that an "off-brand" station has access to the ethanol required to do its own blending.

I see the tank trucks pull up to the "off-brand" stations the same way they pull up to the nameds. The 'cheat' would have to be done up the supply chain. The more people who know about it, the more likely someone would talk.

Interesting points, but the real question is if blends with >10% ethanol are safe to use.

Ethanol is subsidised in the US. Otherwise it would be much more expensive.
