anybody running e85 in there car i had been doing some research and thougt i'd give it a try well i started out with 10 glns reagular gas and 10 glns e85 after the first 260 miles i changed the fuel filter because i noticed a drop in fuel pressure that fixed it right up ,eastimated 17mpg in town after that i added 13 glns of e85 4glng of regular to what was left from the first mix of 50-50, the car runs fine,the next fill up will be all e85

How about the corrosive effect of the e85 on all the fuel components? How about the fact to operate properly on all 85 the pcm must be reprogrammed for additional fuel delivery, careful here.

this i why im trying it out for my self ,i have not had one service engine light,the engine is not running lean i even added a 2.5 pulley .i did add 8oz of two-stroke oil as an added lubricant .all the forums i've read seem to be by people going off of other peoples info and have never even tryed it .just speculation at any rate i'll keep you guys posted on my progress.besides all gas has 10% ethonal in it has been for more than 10 yrs now so if it was gonna eat up seals and corrode i think it would have by now

Do what you want, it's your car! E85 was designed for use in Flex Fuel Vehicles (FFVs) only! Most cars are built to run on fuel enriched with only 10% ethanol and are warranted for its use. Big difference in E10 & E85! More and more vehicles are being made to run on E85 — (a blend containing 85% ethanol, 15% gasoline). To find out which fuel is best for your car, check your owner's manual, or ask your dealer, but I will guarantee you, neither one will recommend E85 for use in your 95 Riviera! :grinno:

There are many variables that affect fuel economy (weather, car condition, road grade, tire pressure, air conditioner use, etc.), studies indicate that fuel economy with ethanol-enriched fuels may decrease, but not as likely with E10. E85 has approximately 27% less energy then gasoline; so therefore fuel economy loss varies between 10 to 25%. Like I said; do what you want! :smile:
