I went and got an oil change at the Chrysler dealer today. This was for a 2011 Town $ Country. The service manager offered me a $30 fuel additive to remove fuel tank condensate "caused by seasonal temperature fluctuations".

 

Well, I said, I thought that gasohol would absorb water, that's why no one buys HEET anymore. He stated again that this moisture settles to the bottom of the tank. Really??? Is it still on the bottom after I've been driving for 15 minutes?

 

What do you all think?

There is a problem with condensation at the bottom of underground fuel storage tanks.  Service stations are very careful to not levels go too low or the pumps will pick up the water.  A quick google search shows that water weighs just over 8.3 lbs/gallon and gasoline weighs approx 6.25lbs/gal.  Which one is heavier?  Which one is at the bottom of the tank?  2 lbs is a significant difference in weight.

I believe that ethanol draws moisture. I use Seafoam and marine formula Stabil.

Stabil ethanol and fuel stabilizer treatment 32 oz bottle $ 24.00 treats 320 gal of  gas.   So yea I think he was trying to poke in your business unless he was giving you the remaining 28 ounces 1oz per 10 gal.

Water is certainly heavier than straight gas and will settle to the bottom if it's not agitated.

That's a much better deal!

Old 850 Ford tractor. The sediment bowl was half full of water and badly discolored. Tractor is not running good. Drained the bowl and added 1/2 a tank of 10% ethanol. Couple hours later the old tractor is running like a champ and the float bowl looks like new. Not a bit of discoloration left. That stuff is a pretty strong solvent if you ask me.

It was 70 degree's at the NJ shore today it is to be 35 degree's tomorrow morning that is the kind of temperature change that can cause condensation in fuel tanks unless there full. After the temp stabilizes no worries.

Nope, don't buy it.  Now I do like to use a can of Seafoam maybe once a year for the cleaning benefits, but it's less than $9.  Never heard of any additive costing $30!
