I recently added a bed cover and was surprised that I lost about 4 -5 mpg as a result. Would a wind deflector on the hood or cab help get that back? I dont think the type matters but it is a Gator soft top trifold cover. It does flutter quite a bit more than i expected, which also might be better with an air deflector, but it does great keeping water out.

I have a 2019 Silverado 1500 LT crew cab.

I got a hard tri-fold that had negligible (maybe +1mpg) effect. Maybe the flutter is increasing drag which seems to be your concern. 4-5 mpg is a lot. Over what period of time did you base this on? I will have this amount of difference when comparing city only (16-17mpg) to city/hwy (21-22mpg).

I could get 20 to 21 city/hwy but now can hardly get 18. It has been like since i put it on four weeks ago. Maybe the flutter is causing some of it but dont know how to cut that down if not with a wind deflector.

Have you tried driving around with the cover open or removed to see if that is truly what is causing your mpg loss?  4-5 mpg is a lot IMO.  You will need to try a process of elimination to find the root cause.  It could be the cover or it could be something else that just happened to appear at the same time.

I cant imagine that cover causing that large of MPG. You are more likely suffering from bad gas or similar than drag from a loose cover. A hard cover would add Total vehicle weight increase, the soft covers weight is negligible at best.

Bed covers should help improve aerodynamics. Unless it’s installed wrong I don’t think it would affect gas mileage.

      2007 Silverado classic Cooling fan running

      By Mistycool · Posted

      I am having similar issues.. 08, 4.8L granted I did had a fender bender and minor damage up front passenger side but I don’t think it had anything to do with it.. I had the high and low pressure checked and my fan for my radiator keeps coming on.. replaced the pressure switch and don’t want to keep throwing parts at it. I did have some minor problems here and there like on long road trips sometimes the ac would get a little warm and then on the highway as soon as I give it a little gas or get a little heavier on the petal it started running cooler. Never had an issue with the ac besides the here and there.. but I also started having issues when I fuel up now it takes a bit to start ( super embarrassing) it runs fine and once started ( only happens after fueling up) starts fine any other time. Could they be related?

      Spent a small fortune on fuel this weekend.   $6.69 diesel, 18 gallons of that. $6.99 92-octane ethanol free, 10 gallons of that for yard machines $5.59 87-octane for one of the cars, 11 gallons.   $250+ and I didn't even get a tug.   Hormuz ain't Hormuzin again, did not see that coming...LOL

      Auto start stop disable

      Appreciate the advice. I've watched multiple videos. Most showing the most complex for those that have a center console, to one that showed maybe 2 pieces of trim being removed, like 6 screws, pulling back the screen and switch assembly, and installing the inline module. And this was a new/newer Silverado. That didn't look too bad. All the others show alot of trim pieces that need to be removed. I've broken those kind of tabs/clips on my C8 Corvette trying to get to the battery, and that was a lot less clips than what I think is involved here after watching multiple videos and looking at my dash today. I have one on the way. Called a reputable stereo place about installing it and got a "minimum" price of $175. Ouch! Looking forward to seeing what the instructions have to say.

      Ac not keeping up

      By Atlas · Posted

      Hard to say what the issue might be. Anything from the ability to cool the AC condenser up front, to blend door issues in the HVAC unit, to refrigerant charge, to compressor issues or issues in the lines.   Report back what the techs find on the 29th.   GM has service publications which list acceptable vent temperatures and AC pressures at given ambient temps and humidity. They probably won't touch the system if it's operating within those ranges.   I'm also surprised to hear your 2024 with the L8T is still using R134a? I was pretty sure the HD's had switched to the new refrigerant around 2020.
