Blue Thunder is a very good fuel, not sure exactly what model of BT your referring to but Blue Thunder HP8 is top notch fuel. Some people have an issue with the blue die, insignificant....
The question you have posed is kind of like asking people what car to get, 10people, 10 different answers.
Everybody has different breakin techniques, fuel, rpm, heat cycle, temp, etc,etc.....
For example, I run
Methanol /12% castor oil for break in
