Ethanol

NoRegrets · 08-21-2009, 10:27 AM

Not a boat but I have a Lexus that was recalled due to the ethanol. There were no plastic or rubber parts involved. I am not a chemist or metallurgist so I can’t offer the quality details that you guys did.

The recall was to replace the 8 fuel rails (there are individual injectors for each cylinder) were made of a metal that could corrode with the ethanol / water properties mix. They were fine with normal gas. Instead of risking a quality problem they replaced all models that had these parts. My car was an early edition of LS460L made for the 2007 model year. Once ethanol was known to Lexus they changed the parts in mid 2007.

Short version of the story – Ethanol can affect some metals and the byproduct of the corrosion may impact the injectors.

Now why did we get this bum product thrust on us?

Al Gore and the group of greedy rich butchers that cut deep into others wallets for their personal gain. He should have stopped at inventing the internet! My blood pressure and temper boil at the thought of......Wait It Is Friday today. A few more hours and I am going to leave work and go to Winnipesaukee! Ah, now that's a better thought. Back to normal. C. J. Avery's for dinner and cocktails, back onto the boat for the night, Naswa for breakfast......

Have a safe and fun weekend all.

I was advised this season by a marina owner who carries both Star-Tron and Sta-Bill that the Sta-Bill formulated for ethanol was probably my better choice because I have an older boat (1990) with a metal gas tank. The Sta-Bill is supposed to prevent the reaction that some metals have that NoRegrets described in his Lexus recall.

I used Star-Tron on my outboard and while it got the engine running again with bad gas it didn't run well and still allowed a build up of sludge in the gas tank to the point where I by-passed the inboard tank in favor of portables, not something I want to do at the lake.

The other thing I am doing is keeping the gas tank full full full when I am not going to be using the boat for over a week. Leaves less room for moisture to form.

or the other school of thought,the moisture is absorbed by the alchohol it isn't just from condensation because it isn't a sealed but a vented system it will attract the moisture. I keep mt tank empty with seafoam and stabil for ethanol.

Actually since ethanol became an issue in my neck of the woods a few years ago I was told specifically to avoid any alcohol base gasoline storage treatment entirely!

I look at all gas treatments contents. Mosy of them are alcohol based. Including Seafoam. Stabil and Star-tron are not.
