I have no idea if this has been suggested yet or not, but it bugs the crap out of me every time I see oil and lava make obsidian.

I see this could be done one of three ways: when lava and oil touch, all the oil is turned into lava instantly, all the oil vanishes, or the oil is actually "flammable" according to game mechanics and burns until it disappears..

as stated in the readme file: post sugestions here

sorry but we try to keep github for the developers, only open something on github if it's a bug you are going to (try) to fix or if it's an idea that already has been approved by the comunity and you are implementing. Just so we know who is working on what

we have a new forum here

I totally understand. Thank you for explaining and not being an asshole. I searched "Buildcraft Suggestions" and I got the old forums, which I could not register for (the out of date link seems to only be on the forum front page). Then I found the Github and posted here.

Oil used to be flamable in 1.4.6 buildcraft, I know as I have a world where a volcano has set the entire oil field alight. It's trivial to fix we want that oil fires back.

Pease add it that Fire use Oil Up when it is burning on It. Its a thing what is missing!

Talk about grief. Not only is your Oil burning, but it is also lost. IF we let the Oil be consumed by fire we should also add a tool of some kind that can help extinguish it in a reasonable time frame.
