capoeirajosh Report post Posted May 3, 2015 Hey, everyone! Just got a new truck! 2014 Chevy Silverado LT 4x4. I see on the window it says FlexFuel E85 Ethanol. Do any of you run this stuff? Any benefit? Share this post Link to post Share on other sites
AZbowhntr Report post Posted May 3, 2015 I don't know if I have ever been to a gas station that sells it down here. I know up in Idaho where I am from 85 is the regular low grade. I have the Silverado with the 6.2 and it was fine. But it was also only a few tanks of gas. Share this post Link to post Share on other sites

capoeirajosh Report post Posted May 3, 2015 It is cheaper over here in N Peoria. I think it is $2.19 Right! I saw that! Price is looking good. Just wondering if you get better gas mileage with it or if it is better for my truck. I have the 5.3 v8. Share this post Link to post Share on other sites

HuntHarder Report post Posted May 3, 2015 From What I know, your mileage will go down between 20-30%. Atleast this was the case with the previous e85 capable vehicles. I have not heard of any big improvements on the newer vehicles to change the MPG. I say you do a test and give us the results. 5 Share this post Link to post Share on other sites
elkaholic Report post Posted May 3, 2015 why bother - I got a 2013 and have no intention of using flex - fuel -- averaging 18+ on my 5.3 on regular Share this post Link to post Share on other sites
Savageman25 Report post Posted May 3, 2015 If the price difference isn't around 40 cents or more than don't bother. You get less mpg. If e85 is more than 40 cents cheaper then it's benificial. Share this post Link to post Share on other sites
reganranch Report post Posted May 3, 2015 Gasoline energy density 114x10^3 BTU/gallon E85 energy density 81.8x10^3 BTU/gallon 28.25% less energy dense. Huntharder was pretty spot on with a minimum margin of error. 1 Share this post Link to post Share on other sites

Right now I am averaging like 17.5 mpg using gasoline. Share this post Link to post Share on other sites
capoeirajosh Report post Posted May 3, 2015 I also heard from the dealership that you get more HP with the e85. Not sure if this is true or not. Share this post Link to post Share on other sites

HUNTnTAT2 Report post Posted May 3, 2015 Ive had my 2014 silverado lt 4x for A year and a half. E85 has less mileage. More horse power. Most times Less expensive. I find I burn through the tank quicker than with gasoline. I average around 18/19 mpg. Now that gas is going up ill probably be putting more e85 in it. 1 Share this post Link to post Share on other sites
