Gasbuddy doesn't track E85 fuel prices, so I went to the government's alternative fuels database center, and found the closest station selling E85 (which was a Sheetz station in Raleigh). I used to find the price of regular gasoline near me in the 27513 zip code area ( $1.84/gallon at the Shell station nearby). I went to the website and looked up the mpg for my Suburban using regular gasoline and E85 ( 16 & 12 mpg). įirst, I needed to collect a bit of data. So of course I decided to analyze this question using SAS software. But I wondered if it was really a better deal, since you get fewer miles per gallon with E85. The Suburban is FlexFuel capable (meaning it can use E85 fuel), and the previous owner mentioned that he had recently filled it up with E85, since it cost less than $1.50/gallon (about 30 or 40 cents cheaper than regular gasoline). So I got a 2007 Suburban LS 4wd, with the 5.3 liter v8 engine - it's got twice the space & twice the horsepower of my Cherokee, and is 1/2 the age! So I studied the used car market for several weeks, and decided that a Chevrolet Suburban would be the perfect special-purpose vehicle (to go along with my Prius daily driver). And although it's never broken down, it's getting too old for me to trust with a high degree of certainty on a long trip. And I don't think it could safely tow my 30-ft boat. The Cherokee just won't hold all the DJ gear I want to take when I play music for a car show. It never left me stranded, and has been my favorite vehicle.īut, as my hobbies have grown, so have my vehicle needs. I used it to haul DJ gear, pull trailers, and transport kayaks & canoes on top. I've been the happy owner of a 1995 Jeep Cherokee for 21 years. But can you guess whether it is more economical for me to use E85, or regular gasoline? Read the SAS analysis below to see if you guessed right! 6) Using map 7 requires 50-60% E85, the back end flash, AND the fuel pump upgrade.I recently bought a vehicle that has FlexFuel capability and can use E85 (mostly ethanol) fuel. We suggest this inexpensive inline option. 5) Most cars will need an inline fuel pump upgrade OR meth to run more than 50% E85. Alternatively you can add in a port injection kit, meth kit, or TBI injection kit, to augment the high pressure fuel pump. If it drops below 9 wide open throttle then you're maxing out the high pressure pump and need to lower the E85 mixture or lower the boost in the areas where it's dropping below 10. 4) Finally after the flash and low pressure pump, you need to keep an eye on the high pressure pump. The E85 flash also features VANOS changes, higher than factory timing advance, and some other stuff designed to help make more power on E85. If they are exceeding 50 in the JB4 logs & open loop is already at or above 90, or if you get 29F2 codes from having too high of an open loop, then you need to add the a back end flash for E85 fuels to extend the fueling range. If that is dropping below 50 then you're maxing out the low fuel pressure and should either reduce the E85 mixture or add a Fuel-IT Stage1 fuel pump upgrade. You'll want to first look at your low fuel pressure in the JB4 logs. 2) For those wanting to run higher mixtures (and more power) then you need to datalog.

If so what mixture should I use? 1) Generally speaking you can run 30-40% E85 without the need for logging or worrying about fuel trims, fuel pressure, etc. E85 offers HUGE octane increases and when combined with the JB4 it came make some serious power!ĭelivey is FREE in the GTA (Kitchener to Oshawa)
