hey guys this is probably a thread already but search engine sucks so i figured id get everyones opinion...in everyones personal encounters, what do you guys find is the best oil??
what sparked my curiosity: my buddy has a 08 civic si, he recently switched over from conventional to mobil 1 synthetic.. after the oil change the car ran horrible, slugish, noisey, ect.. i mean rough!! so he drained it back out and replaced it with conventional oil and it ran perfect again....i was considering changing to synthetic or atleast partial but im not sure now...please feel free to offer any opinions, all are welcome! thanks guys!
