Say if you just got a 240 (s13), w/ a k24de, or it's around the time for you to change your oil. Is there anyway to get rid of periodic carbon build up. What is the safest thing to use, and what are the safe steps to using it?
Figured it might help to get everything to its peak performance when you gotta change the oil anyway.
BTW I did a search, but there's a lot of uncertainty
ThanksChris
