    part B - what octane booster is consider the safest and effective to buy ?

    Available for 2-1/4” or 1-1/2” hoses.

    we just fill at the pump though. You can wedge a regular pump nozzle between the spring plate and lip of the female receiver on the car. At 3mpg you’d need a lot of jugs for a weekend. Or a couple 55 gallon drums.

    98 or 100 unleaded race fuel is available at most tracks near us. But I actually think it will run just fine on 93 octane unleaded in America. US octane rating is different than Europe. 98 RON (EUR) is equivalent to 93-94 octane (US)
