Was talking with a friend on this, he says the Regular Gas (93 Octane) will Degrade the Racing gas (110 octane). I always thought it was the opposite. If you have and 20 gallon fuel tank and have 10 gallons of Regular 93 Octane gas and add 10 gallons of Racing Fuel at 110 Octane; what would be the Octane rating of the mixed fuel in the 20 gallon tank ? I'd say it would be somewhere around 101 octane. What say you on this ? I know you could run all 20 gallons of Racing fuel but at $12.00 per gallon that would be a $240.00 fill-up, can't afford this. Also, the 10% Ethanol in the 93 octane gas comes into the picture.... Also, what about mixing with Aviation gasoline.... I've heard good and bad on this, something like AvGas has additives to keep airplane carbs from icing up in higher altitudes. Any views on this ? This mixed gas is for my 69 Charger with a 383 Magnum engine, stock rebuild.
