Why a fuel saver makes sense right now

As we rely more on our cars for daily driving, the expenses and emissions can quickly add up. SynGas is a practical way to help address both issues.

>$2,500

That’s the average amount people spend on gas every year. For most, that breaks down to spending well over $200 a month just to commute and run errands.

4.6 Tons

On average, this is how much CO2 a typical passenger vehicle produces annually. Using less fuel naturally helps reduce that carbon footprint over time.

What SynGas actually does

Adjusts to how you drive

The concept is pretty basic. Most cars are tuned from the factory to favor performance over efficiency. Once you plug SynGas in, it maps your driving habits for a few days. After that, it adjusts the engine control unit (ECU) to run a bit leaner when you're just cruising, which saves gas.

Fits basically any car

If your car was made after 1996, it has an OBD2 port. That's the same plug mechanics use to check the check-engine light. You just find it (usually right under the steering wheel) and push the SynGas device in. No tools needed, and you don't have to be a car person to figure it out.

Installing SynGas in OBD2 port

Completely reversible

A lot of people worry about messing up their car's computer. The good thing here is that the changes aren't permanent. If you ever want your car to go back to exactly how it was, you just unplug SynGas. The ECU resets itself almost immediately.

Common Questions

Will SynGas damage my battery?

No, it uses very little power. It essentially goes to sleep when your car is turned off, so it won't drain your battery overnight.

How long until I notice a difference?

Generally, it takes about a week or two of normal commuting. SynGas needs some time to gather data on how you accelerate and brake before it can optimize anything.

What if I don't like it?

We do a 30-day return policy. If you check your mileage after a few weeks and don't see an improvement, just mail your SynGas back and we'll refund you. No big deal.
