Not sure how many times its been posted....hopefully not many times..but its OC racing (Overminds Challenge Racing). It a really good time waister game. It has alot of parts to upgrade, and alot of cars you can buy...You get 100 races daily - Max is 600 - and your fuel tank holds 80 liters of fuel. Gas prices change everyday. There are tournaments, you enter 2 per day. There are racing teams but I choose to stay out of'em (really no use for them). Uhh...Thats all i can think of to tell you about the game...The link is below.
