#11 of 13 '00 suburban + ethanol = great pleasure by suburban68 May 01, 2009 (10:09 pm)
Hi all. I own a '00 (gmt830) Suburban that has been equipped with an aftermarket E85 kit. Runs fine, more silent at idle, sounds greater at 2500-3500 rpm and more power when running on Ethanol. Kit was installed by the owner before me. Running on Ethanol with this 5.3litre is genius! Olivier (France)

Replying to: kiawah (Apr 19, 2009 8:59 pm) I thank you so much for that information, as I said I needed a guru and there you were. No need to get excited about trading for a 2009 unless of course my good wife says I should anyway............... Once again thanks for your comeback, it truly is a "peace of mind" to me.   I have not seen any 85% ethanol stations and we have lots of regular unleaded gas outlets here in Ontario.   Have a good day.

Replying to: whitey1940 (May 10, 2009 7:51 am) just a word about consumption and co2 emissions   If regular unleaded gives 100% CO2, 5% ethanol gives 97% CO2, 85% ethanol gives 25% CO2. Cleaner! source: http://www.etha-plus.ch/fr/infos-pratiques/differences-e85-essence5.html   About consumption, no noticeable difference between regular unleaded (I can buy some in the very near Switzerland) and 5% ethanol which is the standard unleaded distributed in France. When you play with 85%, big change. As Ethanol gives a poor burning in the engine (about 20% difference), injection system reacts to obtain stoechiometric mix, to have the best explosion in the cylinder. You then can see consumption change from 20%. My 'burb goes from 16 litres p. 100 km to 19... calculate, that's 20% difference... Regarding prices (and in France it's sooooooooo high), E85 is cheaper than regular unleaded (0.85 Euro vs 1.16 Euro per litre/ 1.16 USD vs 1.59 USD / 1.35 CAD vs 1.84 CAD ). About 20% today, few months ago it was really worthy to run Ethanol because the gap was higher. And remember, you can run up to 10% Ethanol with no mods on the engine. I own an old beast ('92 Ford Explorer, V6, 4.0 litre) than runs a home-mix of 50% unleaded 50% E85. Funny, powerful, cleaner, despite its 314.000 km (about 198.000 mi) Yes, Ethanol can be adapted to most engines Even if no FI system and no CAT, running on Ethanol may require a timing setting, that's all. Don't forget the first car running on Ethanol (in this time, it was called 'alcohol') was a car called Ford Model T...
