Dexbot Q-12 is investigating the source of these Asphault Thieves and is requesting your aid in his search.
return to the same spot where you had previously beaten up some Asphault Thieves. this time however you dont need to attack but go over to
a asphault thief crater.
inspect crater, really all you need to do is run over the spot indicated.
Dexter then notices a fluid in the crater and thinks it might be streetgrinder fluid and asks you to beat a streetgrinder to get some of its fluid to compare it to the fluid found in the thief's crater.
beat streetgrinder for fluid.
once you have the fluid return to Dexbot Q-12 to complete the mission
