Narrative:

With the arrival of the new 900s; fuel has been calculated wrong. When I thought numbers were off at first I was brushed aside and was told because the engines are more efficient the numbers would be different. Then another dispatcher thought the numbers were way off; so he and I started discussing a different release; he involved the 900 coordinator. Eventually the conclusion was that reserve was incorrect; as it was only calculating one engine versus two. I have dispatched a couple different flights with; at least incorrect reserve numbers and burn numbers for the last week. The 900 coordinator concluded that it was 'fine' because there has been extra fuel and the engines performance is better than what is planned and the fuel is ok. I feel this was a safety issue as the required takeoff fuel has been wrong this whole time. Basically I thought I was planning for 45 minutes in reserve; but really was off. Due to another dispatcher's persistence; the 900 coordinator looked more closely at planning numbers. Calculation errors on it and or management. Also; a way to manually check computer information is not available. Better training on the 900s might have helped this situation.
