Birch Performance say: We're blown away at how well this product performs. Through recent times the higher octane fuel at the petrol stations has been very poor due to slow turnover and we have supplied a lot of this product to people who have experienced engine knock and poor performance due to fuel issues. Each and every time the feedback has been excellent. Under normal circumstances a bottle or two of this in your fuel tank will help the car feel more responsive in addition to providing extra engine protection against knock or detonation. Highly recommended.
