Diluting E85 in daily driver

[Hiitman]

I have about 5 gallons of E85 leftover from the summer that I want to dispose of in my completly stock 92 tsi. What would be a safe ammount to add in with each tank of gas?

The max depends on your fuel system setup. If you were to just add it in without any adjustments, something like 25% total fuel volume will keep you within fuel trim adjustment ranges.

If my math is correct, you need to dilute about 9 gallons of 100% gasoline to bring it down to E10 which is used at BP gas stations.

When E85 was cheaper than gas, I would wait 'til I needed a fill up. I'd put in 3 gal. of E85 to about 13 gal. of gas.

I had no problems except the engine light would come on intermittently quite a bit, which is understandable. Mine is an N/T so I don't know how much difference that makes if any.

Use it, 2.5 E-85 per fill up.
Or have some fum with 1.75 gallons per fill..
No timing pull is always fun!

I was running 3-4 gallons on a fill up from mostly empty. I burned a valve in less than 700 miles in a bone stock 92 AWD Laser. So be very cautious. I highly recommend against this. I run straight E85 in my colt with no issues however. And have been for over two years. And been running E85 for nearly four years now in cars I have owned.
