Archoil Challenge Series – 2000 F350 7.3L With 165k Miles & Original Injectors
Replacing injectors on the 7.3L Powerstroke is not cheap. Today I singled out a real “hard-case” where the owner told me another shop advised him to replace the injectors. It’s a 2000 F350 with 165K on the 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.
FYI: In the video Bill uses Archoil’s “P-1” kit to revive the injectors.
What causes 7.3L injector failure?
The 7.3L Powerstroke utilizes HEUI fuel injector (Hydraulic Electronic Unit Injector) technology. What that means is that the 7.3L Powerstroke uses engine oil pressurized from 450 to 3,000 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 7.3L injectors. Poor quality fuel is a recipe for 7.3L injector disaster.
What are some common symptoms of injector failure?
- Hard Starting (especially with a cold engine)
- Low Power
- Excessive Smoke
- Rough Running
- Bucking / Jerking
