PTO Dynamometer Testing
Measured testing focused on horsepower, RPM stability, vibration, smoke reduction, and engine performance under controlled operating conditions.
Testing Focus
- Horsepower output
- RPM stability
- Smoke reduction
- Temperature monitoring
- Engine vibration
- Operational performance
PTO Dynamometer Test Conclusions
Testing showed measurable improvements in horsepower, load response, temperature, vibration, smoke, smell, and blow-by after treatment with Forté Premium ULS Diesel Booster.

Horsepower
A new 4020 is rated at 94.5 HP. After 120 minutes with Forté Premium ULS Diesel Booster in the fuel tank, horsepower increased to 100 HP.
RPM
With Forté, more load could be applied to the engine before horsepower dropped.
Temperature
Manifold temperature dropped. Less friction and more power meant the engine did not have to work as hard.
Vibration
The tractor began running smoother immediately after the tank was treated with Forté.

Smoke, Smell & Blow-By
Prior to treatment, the tractor produced significant smoke and noxious odour. Within 5 minutes of running with Diesel Booster in the fuel, the exhaust was noticeably clearer and cleaner.
Crankcase vent tube blow-by was also noticeably reduced as the test progressed, eventually reaching almost no noticeable blow-by.
