Hi everyone.

I have a car that was mapped in a different country for e20 fuel . When it was imported it had half a tank of e20 and it drove great.

Where I live the only fuel available is e10. I will be getting the car mapped as soon as I can get a slot with a tuner that can work on the car. But in the mean time I have a few places I need to bring the car and I've run out of fuel.

I bought a barrel of c85 and mixed it down with e10 in the correct ratio to make e20 .

This is obviously not a long term solution and it's been mainly used to start and move the car around the yard. But car runs very well on my frankenstien mixture.

There is a show roughly 400km round trip distance from me next weekend and I'm wondering if I would be crazy to drive there using my home made fuel combination?

Is there any major safety concerns I should have related to my engine ?

Engine is a single turbo 2jz and it's currently on a hks fcon ecu .

Mate, you are absolutely fine with driving it on e20 of your own mix- nothing to worry about at all.

Thanks shota

I won't be doing any hard driving ect , it's more just to move the car around till it's mapped.
