As a player who has just installed Real Fuels, I have a few questions that I am seeking clarification for. Please forgive my ignorance if these questions have been asked before. Firstly, what are the different tank types for and what differences do they have? Secondly, must certain tank types be used with certain types of engines? Thirdly, is it possible that the FAQ on the front page could include a short section dedicated to explaining the different tank types? While I might have missed out the information, I do believe that a small overview of what the different tank types mean for the user on the FAQ would benefit new users of RF.
