As we all know E85 At the pump is usually considerably lower than E85 maybe E70.

My question is can you use E98 to get what every you Pump E85 come in at to get it up to E85.

If so is there a formula out there can be used to calculate the volumes needed

Yes you can add e98 to e70 to bring it up. About (that's the key word) one quart e98 to 5gals of e70 works. Remember add and test. If you add too much and get e87 even e90 no biggie. Btw for what it is worth. My sbc 400 bracket motor will run basically the same on as low as E75 as E90. Our pump e85 here in central Georgia can be as high as 90 in summer,but winter is usually dead on 75. Motor is at 13.5/1 compression. I have no signs of detonation with any of the pump blends and as I said, performance is basically the same.

Here in the north I am being told that most are E70-E75 during the summer. I would go back and run Meth but locally that is to expensive, (my local track wants 75-100 dollar for 5 gal can). I can get about a hour away from my track at about 2 bucks a gal, but I have to buy barrels, and don't like having barrels as I live in the city limits, and I am no sure if that would be legal.

Thanks for you response Wooley.

Mr. Bill, if you are going to run e85 go ahead and buy the tester from quickfuel. It is a glass tube, real easy to use. That way you can test your e 85 when you get a jug home. I have e98 available a short drive away, but have to get it in 55gal drums. That is the only problem with haveing to mix my own. I usually just buy pump e85 and run it. Early September before winter blend comes in I will get 25 or 30 gallons. I don't race but a few times a year and usually use less than 50 gallons all year.

I should have looked in my log book notes before I answered you about the mix. It takes two quarts to five gallons sometimes two and a half quarts. That's what I get going but memory.

When you run e70 in a carb that was set up for e85, do you change jetting or anything in the carb set up when your running the e70?

I have not made any changes to the carb. Run the same jets all year round, just change dial in. Like gas I am faster in spring /fall than summer. Only difference I have noticed is with e75 cold start up is easier.

Around here the plunder pumps are usually run around mid to upper 70s the few locations that don’t use plunder pumps run low 80s. We always check ours at the pump before buying. We have a few 15 gallon plastic drums we fill and then usually transfer into five gallon jugs checking it as needed for a race. Never had to make any carb changes, just keep good records to predict the dial in.
