The smart plug-in device that communicates with your vehicle's ECU to optimize fuel delivery, timing, and throttle response — reducing fuel consumption by up to 55% with zero mechanical modifications.
SynGas connects to your vehicle's standard OBD2 diagnostic port — the same 16-pin trapezoidal connector used by mechanics. Once plugged in, it engages in real-time bidirectional communication with the Engine Control Unit (ECU).
Over approximately 150 miles of normal driving, the device reads live performance data and progressively fine-tunes engine management parameters — including fuel delivery, injection timing, and throttle response — tailored specifically to your vehicle and your driving habits.
SynGas delivers measurable fuel savings and engine optimization without any permanent modifications to your vehicle.
Reduces fuel consumption by 15% to 35% on average, with a best-case reduction of up to 55% after full calibration.
Real-time bidirectional communication fine-tunes fuel delivery, injection timing, and throttle response specific to your engine.
Installation takes under 3 minutes with zero tools or technical knowledge. Just locate your OBD2 port and plug it in.
Works with virtually all OBD2-equipped vehicles — gasoline, diesel, and hybrids — from cars and SUVs to trucks and vans.
No permanent changes to your ECU. Simply unplug the device to return your vehicle to its original factory settings at any time.
By burning less fuel, SynGas helps reduce CO₂ emissions, contributing to a cleaner environment with every mile.
One-time purchase with no subscriptions, no hidden fees, and no maintenance required. It just works, silently and efficiently.
Easily transfer SynGas to another compatible vehicle. The device initiates a fresh learning period to optimize for the new engine.
Try SynGas risk-free. If you don't see meaningful fuel savings after the full calibration period, request a full refund within 30 days.
No tools, no technical skills, and no mechanic required. Anyone can install SynGas in under three minutes.
Find the standard 16-pin trapezoidal connector — usually under the dashboard near the steering column.
Firmly insert SynGas into the OBD2 port. It fits securely without any adapters or wiring.
Turn the key or press the keyless start button once (without pressing the brake). The device powers on automatically.
That's all. SynGas calibrates itself during regular driving. No special procedures or adjustments needed.
SynGas is compatible with virtually all vehicles manufactured after 1996 in the US and after 2001 in Europe that are equipped with a standard OBD2 port.
Cars & Sedans
Trucks & SUVs
Vans & Crossovers
Gasoline, Diesel & Hybrid
Also compatible with keyless start systems and light commercial vehicles across all major manufacturers.
By optimizing fuel efficiency and reducing overall fuel consumption, SynGas helps lower carbon emissions with every mile driven. It's a simple, accessible way to contribute to environmental sustainability — without buying a new vehicle.
SynGas comes with a no-questions-asked 30-day refund policy. If you allow the full 150-mile calibration period, track your fuel economy honestly, and don't see a meaningful improvement, you're entitled to a full refund within 30 days of purchase.
Your purchase is completely risk-free. Try it, test it, and see the results for yourself.

"Installed SynGas on my 1999 Buick Regal with 180,000 miles and saw fuel economy improve from about 22 mpg to almost 35 mpg after calibration. Installation was quick and simple, and the device just works silently. Highly recommend for older vehicles with less optimal factory tuning."
Verified Buyer"As a truck owner, SynGas helped reduce my fuel consumption by about 25% according to my logs. It adapts well to larger engines and driving conditions that usually sacrifice economy for power. The reversible install gives me peace of mind."
Verified Buyer"I drive about 40 miles daily and after a week using SynGas, my fuel bills dropped noticeably. The device paid for itself in fuel savings within a month and installation took less than three minutes with no hassle."
Verified Buyer"I was skeptical at first, but after about 200 miles of driving, my SUV started feeling noticeably smoother during acceleration. My fuel log shows roughly a 20% improvement in MPG. For the price, this is a no-brainer — especially with the 30-day guarantee backing it up."
