I have found BP Ultimate works well after sitting for a long time, as i have the same fuel in the tank for about 8 months, and no pinging problems, and i run near 12:1 compression. I recently went in a burnout comp, sitting on 7400rpm for over a minute in top gear, and that old fuel seemed to work as well as fresh fuel. No pinging or breaking down, no dramas at all.
What sort of life does the fuel actually have?
