Roto-dyno tests have shown that with the BMW N52B30 straight six V-power gasoline gives you an average of about ~+10hp and ~+10Nm compared to regular 98E RON fuels. Even higher if compared to 95E RON fuels, but those are not meant to be used in BMW's high-quality engines anyway, even though they can accept anything between 91 to 99+ RON and adjust themselves accordingly. You should always use a minimum of 98E on BMW's if better is not available.

Besides the added power, most BMW owners I know have noticed a marked decrease in consumption in highway driving, depending on the make and model of the BMW car and engine, anywhere between 5% to 13% less fuel consumption using the same average speed on the same route as with the compared 98E RON fuels.

Best regards,
