MPG 6.2l

[Shawn O'Leary]

Most of my driving (with the 6.2l) is stop and go rush hour traffic in and out of downtown Chicago. Usually get between 13 and 15 mpg. That improves a lot when I'm on the freeway on the weekends and such.

I am really surprised that I never see anyone post about using a blend of E85 and regular to make a E30 blend which has 93-94 octane and using that in the 6.2.  A 1 to 4 ratio of E85 and E10 will make roughly E30.  More like E25 in the winter months.  Many in the performance car community do this.  And the resulting cost is less than using regular alone.   Many in the performance car community have figured out that many of the more hot rod engines will not throw a code for ethanol blends of 30% or less. They are designed for at least 15% anyway.  

 

If one does a casual search for E30 in the performance auto forums, you will find a stack of info about those doing it.  Seems, since the 6.2 falls into that category, it would be a good thing to try.   If one doesn't have to pay for premium fuel to get premium performance, then why do it?  I would think getting a 93-94 octane fuel at the same price as regular would have folks fighting each other to get to the fuel pump as quick as they can.

Canadian here... KM's not Miles

 

I have a 2019 AT4, I recently put 20's on.

 

I am getting between 13.1 Liters / 100 KM and 15.0 Liters / 100 KM depending on the driving conditions.

I definitely went down after going from 18's to 20's and after the Air Intake and Exhaust. Expected it though so no worries here.

 

 

 

 

For reference:

10.0 liters per 100 kilometers equals	28 miles per gallon
10.5 liters per 100 kilometers equals	27 miles per gallon
11.0 liters per 100 kilometers equals	26 miles per gallon
11.5 liters per 100 kilometers equals	25 miles per gallon
12.0 liters per 100 kilometers equals	24 miles per gallon
12.5 liters per 100 kilometers equals	23 miles per gallon
13.0 liters per 100 kilometers equals	22 miles per gallon
13.5 liters per 100 kilometers equals	21 miles per gallon
14.0 liters per 100 kilometers equals	20 miles per gallon
15.0 liters per 100 kilometers equals	19 miles per gallon
16.0 liters per 100 kilometers equals	18 miles per gallon
17.0 liters per 100 kilometers equals	17 miles per gallon
18.0 liters per 100 kilometers equals	16 miles per gallon
19.0 liters per 100 kilometers equals	15 miles per gallon

Is this just as simple as filling up with XX amounts of each and the truck does the rest or does it require a tune?

Maybe do a search on here, there is in fact threads on E85

 

i know, I stated one

Any time I have tried it in non flex fuel motors, the stock tune ran things fine.  No CEL and no other problems cropped up.   I have only had flex fuel vehicles for the last 5 years, so I have no current results with non flex fuel versions.   Many in the Mustang and other performance cars community run E30 with stock tune and get good results.  E30 is a 92-93 octane fuel which these high compression motors need. And from what I have read, there seems to be no problem and is a growing practice with those owners.   Some have indeed put alternative tunes in.   

 

Go look on some of the performance sites and you can find discussions on doing E30.     Since E30 would be about the same price as regular fuel while delivering Premium fuel performance, that alone should cause some to give it a whirl and see how it works for them.

Getting around 15 to 16 in mixed driving and over 20 on the highway all on 87 octane. No noticable pinging. Seems awesome so far.

I just completed a 438 mile with lots of speed changes ranging from 35 mph to 70 mph speed limits. I typically set the cruise for 8 over the speed limit and averaged 19.2 mpg. I feel if I didnt use the cruise I probably would have been around 20 mpg. I also am running 24" wheels which are a little heavier than the stock 20's. Typically the dic averages higher than my actual mileage when calculated manually when I fill up. On this long trip the Dic calculation was lower than the actual mileage.

Would E30 give you the same mpg as premium 93 or would it be crappy like e85?  

[OnTheReel]

 

Mostly highway, most of that was at 75-85 MPH. Couple remote starts and short trips mixed in too though. City driving hurts, speed hurts. If you are in an area where you can hang out at 65 or so, seems like an honest 23-24 MPG is attainable.

Pretty sure E30 would not deliver the same mpg as premium, but given that E30 is about a about 80 cents a gallon cheaper than premium, I would be willing to bet that even with the lower mpg, it would still be far cheaper per mile than using premium.

 

I probably only lose a hair over 1 mpg by using E30 compared to even E10 regular.  In that comparison,   E30 is about 15 cents a gallon cheaper than E10 regular, so again, even by losing 1 mpg E30 is still cheaper to use than E10 on a cost per mile basis.   And I get 91-93 octane where E10 regular is only 87 octane.

 

Of course, prices vary across the country, so the price spreads may not be there and it may not be worth trying.

I may have to try this when travelling with the rv.  In houston I use my kroger fuel points to save $1 on every gallon so it's not worth the hassle.  But when I'm in other cities it might be worth a try.  Thanks.

What kind of fuel range are you guys seeing out of your trucks? I believe the 1500 has a 26 gallon tank, anyone run there’s down until the fuel light comes on? I’m curious how many gallons you were able to put in. 

[Mudcon]

Every morning coming to work my clusters says 14-15ish but when I check the app it says on the last trip was 18mpg.  Those are on adverage numbers but I dont know which is right. 

[6.2TB]

Picked up my Trail Boss Friday night, took my first road trip yesterday. Averaged 23.5 on my return trip, 2 lane mountain roads with maximum speed limit of 55.  I can’t complain about that!
