I’ve been using SynGas for about a month and it seems to do its thing on my usual commute. But I’m in a lot of stop-and-go traffic and was wondering if that kind of driving messes with the learning or if it just adapts to it like everything else. I haven’t noticed any issues, just curious if it’s actually doing anything in those situations. Not expecting miracles, just wondering if it’s still helping when I’m crawling along.

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.

Mine seems to keep doing its thing even when I’m stuck creeping along in traffic. I do a lot of school pickup idling and it hasn’t thrown anything off. Honestly the smoother pedal feel is what I notice most in stop and go, not some big mpg jump.

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 do a ton of stop and go on my way home, like 40 minutes of basically crawling, and mine still seems to do something. Hard to prove on a single tank but my average mpg number on the dash has stayed a bit higher than before I plugged it in, even on weeks where traffic is bad. The bigger thing I noticed is the throttle feels less jumpy when I’m creeping forward and braking constantly. Not a huge change but it’s there. I think the learning part just adjusts to whatever you normally do, so if most of your driving is traffic, that’s what it picks up on. It’s not like it needs highway runs to figure you out. Whether it saves much fuel in that specific situation I couldn’t tell you, but it hasn’t felt like it gave up in traffic.

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.

Mine still does its thing in stop and go, I sit in a lot of it on my way to work. The bigger thing I noticed was the shifting got less jerky after a couple weeks. Fuel-wise I can’t say I’ve seen much in that kind of traffic though.

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 didn’t seem to do squat in bumper to bumper stuff. It was the longer stretches where I actually noticed a difference. Stop and go is just going to eat gas no matter what you plug in.

[Dave the Curious]

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.

[Lisa Hall]

Mine behaved differently in stop and go than on the open road. It smoothed out the throttle a bit, which honestly made the crawling less jerky, but I didn’t see any real fuel savings until I started doing longer drives. So it’s doing something, just not the thing I bought it for.

[Devon Lee]

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.

[Lisa Hydrow]

I don’t think stop and go messes with the learning at all. Mine has been in for a couple months and I do mostly short city trips with tons of red lights, and it still picked up my habits fine. The traffic part is just part of what it learns, not something that confuses it.

[Emma Mirren]

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.

[Jordan Writes]

Fair enough, I’ll just keep letting it do its thing.
