Im not due for an oil change but is it a good or bad idea to put an additive in there just to keep things free? Its a 5.7 with M1 synthetic i put in about 5k ago. Ive looked at Lucas oil but they have two diff additives that look like they do the same thing. But i cant decide if one is better than the other.... chime in for any helpful advise.
