SynGas and stop-start traffic, does it help there?

Mine seemed to take longer to settle in than the 150 miles they mention, probably because my commute is mostly short trips with a lot of waiting at lights. I think the stop and go stuff actually gives it more to work with in a way, since it’s seeing how you handle creeping along and light throttle. I noticed the smoother feel more in traffic than on the highway honestly. Hard to say if the mpg gain is as big there though, since that kind of driving is just thirsty no matter what. But it didn’t seem confused or anything, it just kept doing its thing. Curious if anyone else noticed the difference between highway and city driving with it.

Traffic probably isn’t the main thing it cares about, but I don’t think it does much when you’re barely moving either. My mileage gains mostly showed up on open road, not in gridlock.

I’m not convinced it does much in that kind of traffic. Mine only really started showing gains once I was doing longer stretches at steady speed, the constant crawling never seemed to change anything. Stop and go is just where these things have the least to work with.

Stop and go is where mine actually surprised me. My morning crawl to the office is 25 minutes of pure brake and gas, and I started seeing better numbers after about 3 weeks of that. Longer highway runs didn’t change much for me.

Mine still does something in stop and go, but it’s way less noticeable than on the highway. I’ve had mine about two months and honestly the crawling parts feel basically the same as before. If you’re mostly in traffic you might not see much.

I do a mix of highway and city and my experience has been a little different from what some folks are saying. The stop and go part is actually where I noticed my fuel numbers stop bouncing around so much. Before the device, my tank average would swing all over the place depending on how bad traffic was that week. After about a month and a half with it, the bad traffic weeks don’t drag my average down nearly as much as they used to. It’s not like the car magically sips fuel while idling, but the overall weekly number stays more consistent, which I appreciate. The 150 mile learning thing probably matters here because the first couple weeks I wasn’t sure it was doing anything at all. Once it settled in, the difference in consistency showed up. So yeah, I’d say crawling traffic is still part of what it’s working with, not something that throws it off.

Stop and go is actually where mine did the most, but not for fuel really. It made the throttle less touchy so I wasn’t lurching forward every time traffic moved a few feet. That alone was worth it for me, the mpg thing was secondary.
