HI there for the past 5 years I'd fill a tank of gas, half with premium gas and the other with regular. I'd do this once a year. I've been told by my neighbor to fill the car with premium gas 5/6 times a year and use a fuel additive on a full tank of gas? I put about 7,000km on my civic every year?
