Not remembering what the last code that tripped before i used MM i got irritated thinking id have to take it to a shop and spend a couple hundred bucks BUT I Turned to Marvel again before needing a fill up and drove the car a week and the code reset its self so im guessing again my egr got cluttered with carbon deposit and the marvel burnt it away.This stuff is really amazing (-_-) ### ⭐⭐⭐⭐⭐ The mystery oil *by J***S on November 9, 2024* Great upper valves lubricant.
