For me, it's not so much the fuel stealing, it's the idiot that comes by fit no reason and puts something in there besides free fuel... Say you have your favorite teams sticker on your window, some rival fan decides he's going to be a hero, and add something to your fuel. You will not know until it's too late...

 

 

Good point.

 

 

That's the reason I had a locking door (not cap) on my old '98 and my '14. A locking cap is cheap and most if not all doesn't seal as good and usually throws a code. The only reason I worried was because a few years ago kids would mess with people's vehicles. One time someone shot BBs at a handful of cars trying to shot on windows. Luckily they missed my '98 and hit just below the window and left a dimple. Then someone went and slashed a tire on 3 or 4 trucks including mine. Now a days there doesn't seem to be a problem, but you never know.

if you shake it more than twice, your playing with it.

You can buy a cap to plug it. Don't know why anyone thought this was a good idea.   Sent from my SM-G920V using Tapatalk

Emissions. A loose gas cap pollutes more. The less human involvement, the less that'll go wrong. Not saying I agree with that but I know that's their logic. Ford has used this system for several years

I miss having my gas cap to hold the service station nozzle going while I clean my windows, etc. Now without it... I find myself going more to the full service station than the cardlock just so I'm not standing there swearing at my stupid truck for not having a gas cap lol

I know most of these trucks rarely see anything but the mall. But in WY, CO, IA, etc. there are lots of dirt/gravel roads and that dust gets into everything. What's the fix?

I ran a Dodge rental on some of that nastiest BLM roads in Idaho, everytime I opened the fuel door, it was clean.

 

If they design it right, should be a non-issue.

Well, since Ford has been out with no fuel cap systems for a while, that might explain why Ford isn't a market leader in Iowa. They never were top dog in Iowa, but they effectively made sure they never would be. And living on gravel roads, you are correct, dust gets into everything. About the only thing dust doesn't get into over time is a container that has never been opened. It is one of several reasons why I don't follow the OLM for my oil changes. And the closest some of the folks who come up with this stuff came to rural living was taking their kids to a petting zoo to pet a goat.

Exactly why GM needs to come up with a locking fuel cap for the 2017 Silverado / Sierra configurations. Anybody find one that works? I bought a chrome locking fuel door and it was advertised as fitting the 2017 but it only fits a 2014 and 2015. The mounting holes don't line up with the existing rubber stops that are used to secure the door to the truck.... Not happy....

I use plastic water bottle to hold pump handle when filling up. No issues

I have a new 2017 Denali I've noticed that without a gas cap there is potential to let dirt and water into the fuel system. I have seen water puddling up in around the filler hole as well as bit of dirt. Any thoughts on how to seal this up a bit better.

 

Not sure what can be done, but it is the way everything is going.

I have this on my Denali, my Corvette and now on my wife's Caddy XT5......hope it doesn't end up being a problem!

I am currently on the process of tracking down the correct part numbers so I can convert my truck to a non-capless system. When I get it figured out, I'll post up...

Have this on my 2017 2500hd, don't particularly like it. Why on earth do we need this? Who is so lazy that taking off the gas cap is a problem? Stupid, stupid, stupid. If Ford makes a cake shipped car, wtf, GM has to fallow? Truly stupid.

This won't help with any locking issues, but there is a plastic cap that goes over the capless circle/hole/structure to keep it clean. Search "WATER DUST GAS CAP COVER 2017 2018 CHEVROLET SILVERADO CAPLESS FUEL FILL" on ebay. I'm going to see if Home Depot has a basic plastic cap like this that will fit.

It's a shame that owners have to resort to this.....it wasn't a redesign it was a too lazy and too cheap kludge on an existing chassis. Glad they didn't do me that favor of a capless system on my '16. Likely more for Chevy than owners so they don't have to reset engine codes or deal with complaints related to a loose or missing gas cap.

 

Doesn't mean they can't design it properly from the ground up. My '18 Traverse has a properly designed capless system with a baffle on the back of the fuel door that fits neatly into a recess protecting the cap area from water dirt and dust plus an interlock to warn if the door is open while driving away. Bottom of the filling hole is tapered outwards so pilled liquids or a driving rain while the fuel door is open will not remain up against the closed door and the hinge area is encapsulated instead of the Silverado's hinge which opens directly into a hole inDSCN0351.JPG.627a56f57b9564a47f8a3171365e14e5.JPG the inner fender open directly to the ground. Outer body covered with road salt and road crap, but the fuel filler area remains clean as a whistle.

 

When using that 25 cent PCV tubing cap it might be a good idea to inform the wife before she fills up or warn a filling station attendant in States where you can't pump your own. Failing to do so, a well placed blow from an unleaded fuel nozzle might be enough to force it into the pipe and really screw up the spring loaded doors.

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
