If you can do it probably depends a lot on whether you have a fuel injection system with a fuel pressure regulator.

If you go to www.etanol.nu (run by some Swedish enthusiasts) and click Ombyggnad and then Insprutare you will see a picture with an adjustable fuel pressure regulator. This is probably what you will need to hike up the fuel pressure to make your car run. Unfortunately, the site is in Swedish, but what I gather by reading thru the site is that the ethanol will dissolve deposits in the system. Therefore you should probably consider changing your fuel filter to start with, increase the ethanol fraction slowly by filling more and more ethanol to see what mixture your car can take, and be prepared for clogging of injectors from old deposits. Cold start may require a Start Spray or similar if temp below 10 C.

If you click Ombyggnad and then Gräsklippare (Gräsklippare means Lawn Mower) a couple of pictures show how you can increase the hole size (percentages given on the page) in the nozzle of your Lawn Mower by just increasing the hole size by drilling it up in size, so you can run it on ethanol. I don´t know if it is so wise.

The site has a forum, maybe you can post in English and see what advice you can get. Bet the guys will be really excited by some foreign language posts.

"E85" is an ethanol mixture sold at more and more Swedish gas stations, contains 85% ethanol, remainder gasoline to keep starting problems at bay, even in cars intended for ethanol.

Have contemplated testing ethanol in increments in my ´93 945 T+ (see a previous post by me), but haven´t gotten around to it due to lack of time and since the 945 is my daily driver. Can´t be without it right now if I run into problems, but I suspect that any car with APC or the turbo plus option would be able to run with quite a bit of ethanol, perhaps even on the E85. Has anyone tried in an APC or turbo plus car?

As for alternative fuels, an interesting history is how Swedish small boat engines used to have dual carburetors so that you started on gasoline, and then switched to light kerosene after engine warmed up. This was in the post-WWII time a cheap product (not so any more). At the end of your trip you had to remember to switch back to gasoline again (by flipping of a valve), otherwise you had great problems starting up again. This kind of engine setup was successively, especially as kerosene got more expensive, replaced by small diesels, made in plenty by e.g. Volvo Penta.

If you go to "Länkar" (means Links) and click BAFF there are some interesting statements about alternative fuels, some in English.

One thing to remember is that E85 and similar fuels have some additives, and I don´t think the last words have been said about the health issues of these. My inclination would be that these new fuels should be used in vehicles with a working catalytic converter to burn any remains of additives. Thus, I would not do the conversion of for example my lawn mower unless I knew exactly what is in the alcohol mixture to be used.

Cheers!
