Optifuel Reviews and Complaints The Optifuel software functions by combining inputs—start and destination points, truck-specific fuel usage profiles, payload and engine considerations, live station-level fuel prices, and optional private fuel contract rates—then running an algorithm that weights cost against detours and time to provide refueling recommendations. The Optifuel OBD2 device works differently: once plugged into the OBD2 port the Optifuel module reads live engine parameters including fuel flow, ignition timing, boost pressure, and driver inputs; the Optifuel module then communicates with the vehicle ECU and applies pre-programmed calibration profiles to alter injection timing, throttle mapping, or other control points to improve combustive efficiency and reduce transient fuel waste. Because the Optifuel OBD2 device is described as preprogrammed and tested on many vehicles, it typically begins affecting fuel use immediately, though actual savings vary by engine type, driver behavior, and fuel quality.
Optifuel Reviews and Complaints The OptiFuel FT-IR analyzer’s specifications are more technical and include a full-range, laser-referenced interferometer, industry-standard calibration models for dozens of fuel properties, wide AC voltage compatibility, a multi-hour battery pack for mobile lab use, ruggedized components to withstand vibration and humidity, a touch-screen interface, rapid calibration transfer, and LIMS connectivity; OptiFuel FT-IR instruments come with long warranties on optics and sources and more than 50 factory calibration models built from hundreds of real-life samples. OptiFuel Systems’ hardware and system-level offerings include Total-Zero™ Diesel-RNG dual-fuel locomotives that are EPA-certified as zero NOx and PM emissions, modular tenders for RNG and hydrogen, quick-disconnect modules for swapping in about an hour, multi-fuel integrated refueling stations, and retrofit and new-build options; the OptiFuel Systems platform emphasizes long range, modularity, and certifications like FRA concurrence and EPA recognition. The OptiFuel International fuel catalyst is described as a catalytic additive that stays suspended in fuel without derogation, is dosable at terminals or directly into tanks, passed “no harm” engine testing by an independent lab (Innospec), and remains compatible with fuel standards such as ASTM and EN; Optifuel additive packaging like a 250 mL bottle is designed for easy dosing. Granby Optifuel de-aerators are UL/ULC listed, include a proprietary fusible link oil safety device, meet CAN/CSA and NFPA codes, and are compatible with biodiesel blends up to B100.
