    I'm running a stock revo 3.3 with optimix 16% fuel I'm running my engine relatively rich and a whole bunch of blue smoke is visible during the acceleration, so i assume that everything should be theoretically fine apart from the fact that the temp was at 280f, i tried richening the needles but...

    Does different nitro content really make a big impact on a car's performance?

    Q1: is it worth purchasing 20 or 25% nitro in Europe when u need a license for it? Q2: I'm running a stock 3,3 engine and wanna know if switching from 20% to 16% really is a night and day difference? Q3: Will fuel with a lower nitro content decreases the life of the engine? Q4: I'm into buying...
