BestLine Premium Synthetic Engine Treatment


Reducing friction and general wear-and-tear of your engine, this additive also improves your fuel performance and economy. On average, after your second oil change using BestLine, you can see a 40-50 increase in mileage on a full tank.

Harmful emissions are reduced as well. This oil additive is optimal at 10-15% oil volume (a bit higher than the standard 5% for most additives, though the performance increase is worthwhile). Engine chatter and vibration is reduced after your second startup while slightly increasing oil pressure.
