i was reading the bord today and read that some people where running a different type of motor oil than what is recomended in the book for a non supercharged enging, what are the advantages of running, i think it was 0w-30 oil? where is the best place to get this oil? and it sounded like you dont have to change the oil as offten as 5w-30 oil. i really really want to get the Urd kit for my turck, when i went to the dealership they made it sound like they just added on one more injector around the supercharger with their 7th injector kit (that and it was more expensive). is it worth voiding the warrenty with the urd kit? that and what shouldnt i do, with a supercharged engine? i just want long engine life, more power is not really my goal. but more power is a nice side affect. if i have more questions i will post when i am of better mind.
