Archoil Challenge Series – 2006 E350 6.0L With 167K Miles & Original Injectors
Replacing injectors on Powerstroke is not cheap. I singled out a customer truck today where the owner told me two other shops told him he needed to replace the injectors. It’s a 2006 F350 box truck with original injectors and it runs pretty awful. Watch how this truck revives once we use Archoil AR9100 in the oil and AR6200 in the fuel.
What causes 6.0L Injector Failure?
The 6.0L Powerstroke utilizes HEUI fuel injector (Hydraulic Electronic Unit Injector) technology. What that means is that the 6.0L Powerstroke uses engine oil pressurized to 450 to 3,600 psi to fire the fuel charge into the cylinder. Therefore, engine oil quality/maintenance plays a critical role on injector performance, especially for worn injectors with high mileage.
Besides oil quality/maintenance, fuel is the second major issue that affects 6.0L injectors. Poor quality fuel is a recipe for 6.0L injector disaster.
What are some common symptoms of injector failure?
- Hard Starting (especially w/ cold engine)
- Low Power
- Excessive Smoke
- Rough Running
- Bucking / Jerking
