10% Ethanol + 95 V-Power

[BlitznB4]

For those of you who are interested - JDM Turbo Subarus are supposed to be run on 100 Octane. 98 is the highest we can get here in NZ. I have to drive 30 mins to get 98 and my B4 Blitzen detects detonation on 95 and reverts the ECU to "safe maps" - which i think retards the timing and decreases boost from 1 Bar to 0.5 Bar. As you may know Gull Force 10 is a 10% ethanol blend and is 98 Octane also - the car runs fine on this, but again have not got access to it. I now buy E100 ethanol and I blend up my own E10 with 95 - 58 Litres 95 and 6 Litres of Ethanol @ $2.25 per litre - Which makes close to 100 Octane. The car not only runs max boost without Det - I no longer have to travel to get 98 - its also cheaper to blend it yourself!!!

I was told its not as easy as just blending the two fuel together, a properly made ethonol blend has alot more toluene with blends the two fuels together better.

I probably doesn't matter so much in your situation (factory ecu) but if it was tuned with an aftermarket ecu closer to your engines limits a bad blend could cause loads of detonation.

from what ive read its much safer to blend methanol

I thought methanol is no good for standard fuel lines as it can cause rust and shit or some shit like that i was under the assumption that toulene was the stuff to use to up the octane rating maybe i better research some more again

Yeah, I was a bit weary about it - I have run 4 tanks of adding 5L per tank with 50L on 95 - the car doesn't "detonate" so to say and cut the timing and boost to 0.5bar like it was without it.

The thing with Methanol i believe is the water content which rusts/damages fuel components.

The car runs well with the blend but I will keep this discussion updated in future should I run into any problems - but so far so good
