HKS DDR VS hydrogen carbon clean up vs engine oil change and general servicing
HKS DDR and hydrogen carbon clean up is enough or just engine oil change for nissan pathfinder 2003 or just either of the 2 for better fuel efficiency and sluggishness to reach 100km/he uphill. I am getting 6km/l right now
