Buildcraft Oil turning into Actually Addition Oil

[bagaznal]

So I went to go pump buildcraft oil from a geyser and when it pumped, it pumped out actually addition's canola oil. Whats weird is the buildcraft geysers look like buildcraft oil, and if you hover over them it says its buildcraft oil, yet it comes out as actually addition oil. Furthermore, when I went underground, it seems that half of the oil in the oil pocket was exchanged with actual Actually Additions oil.
