ethanol in gas bad for our cars?

BTW, if you want to do some research on fuel additives, do a Google or Yahoo search for the MSDS sheet for each additive. For example, for Stabil (a popular marine additive), search for "stabil msds". You will discover that Stabil (red) is 95% isopropanol, while Stabil Marine (blue) is 80% petroleum distillate- very different chemistries.

Pay close attention to the date on any MSDS sheet you find- every time the formulation changes, a new sheet is issued and all the old ones stay on-line. For some companies, like Mercury Marine, you can find 4-5 different MSDS sheets for the product they call a fuel stabilizer, due to all the changes they've been making in the product. The latest-dated MSDS you can find probably reflects what is on shelves today.
