So your conclusion basically boils down to "your mod gives me less EU per unit of fuel, therefore it's bad"?
Nope. Your own conclusion is stupid, sorry. I think it's worst because to me the good EU value per Refined Oil Bucket is about 300 000 EU, with a better than 8EU/t rate. If greg don't think so, up to him. But you basically don't think before writing. To me, it has to be buffed because of f***ing Advanced Solar Pannels (guess what I'm not using FTB ... this and Mystcraft-CCraft-EndlessEUfromNetherwithRC-Forestry) ... and because greengen in general are a bit OP, so to be used Refined Oil needs to be more efficient.
Edit: sorry for flaming you, but you take me for a noob ...
