Archoil's AR9100 oil additive is suitable for use in all diesel and gasoline engines (including Cummins, Duramax and Power Stroke).
AR9100 forms a solid boundary lubricating film that improves performance and protects engines, gearboxes and hydraulic systems.
Why we like this product! - AR9100 eliminates hard/cold start issues caused by HEUI injector misfires in 6.0L & 7.3L Power Strokes.
Most of our customers who use this, say it pays for itself in fuel economy savings, and the incredibly smooth idle it delivers.
