you should be able to mix the 98% and 72% to get 85%.
Don't know your comp ratio, but I would stay away from 72-80%.
Can the mtx-l be set to lambda? The fuel type or percentage isn't required with lambda. .75-.80 lambda will be safe and make good power.

Today I bought some E-98 to add to the fuel. Will this work to help get back around E-85? ^^^It work for me ^^^did you purchase that fuel in a 55 gallon drum? Wondering if it can be purchase in something smaller say 25 gallons .

I have done some tuning on my motor on E85, mostly at a dyno in Klamath Falls OR at 4300 ft. I have since reinstalled the original jets (that fuel teted to be E75 winter mix )but I haven't jetted it up at the track yet on back to back test to see if it wants richer or not I do test the E85 now and find that when the fuel sits in the plastic fuel jugs or metal cans over a period of time the Ethanol content increases, not decreases due to the gasoline evaporating out of the fuel I had 15 gallons sitting in three different containers in the race car trailer since last October, one can and two jugs. They tested in May to be between 87 and 90 % I need to buy some pure Ethanol or at least E98 so I can play with mixing it with the fuel I have to get all of it to a set level of Ethanol instead of having 10 to 15 % differences in batches

If you plan to use much E-85, especially blending your own.....a Hydrometer will be required Monte, what range hydrometer range do you recommmend for E85? I've been testing my pump E85 the the Quick Fuel water tester, I do have gas hydrometer left over from racing NHRA stock back when they checked the specific gravity of all the gas we could run back then. Once they switched to the dialelctric tests all that went away

I have the quick fuel tester Cab_Burge mentioned, but no Hydrometer. I plan to switch where I buy the fuel, and maybe just buy 55-gallon drums of Real E-85 race fuel? When I was running E-85 I tested(same tester as you have)and the one place I bought from it had to be summer fuel and it tested at 85-86 and when it tested good I bought 2 55 gal drums at a time

Some other issues with ye ole pump E85 is what they use to denature it. Sometimes they use something called "natural gasoline", and it's the dregs of the gasoline world. When fuel costs are high, you can bet it's the fuel of choice.
You can water test E85 with a graduated beaker, and determine what percentage the ethanol is. Doesn't tell you what's in the "gasoline" side, just how much.
I've gone to VP C85. Works great with nitrous, and makes more NA power than any pump mix I've found. Trouble is, it's a little expensive, like 5+ bucks a gallon, and it's chock full O MTBE, and some other unsavory additives. Up side is, whatever anti corrosion spooge they use really works. Can sit, and sit without turning to white goo.

At the one place I bought from I always went inside to see the drop sheets for the E-85... all of ours in the Detroit area was a 2 part drop... ethanol and the regular gas... it told what it was and the percentage (number of gals each).. at first(the first couple times they looked at like I was crazy) until I explained what I wanted to see.. usually the manager understood... then I could see the total content of each component.. after a few times they knew what I was asking for... plus they sorta got use to me

I get my VP-101 unleaded from a local Arco station is that junk too........... That's not pump gas. And as far as knowing the percentage drop like MrP said, that still doesn't tell you WHAT they dropped, just how much of it
