Wiggums

I have 3.23 on mine and I believe the 2019 V8 is more efficient with the DFM. I don't use the cruise control, I maintain a steady foot on the gas pedal so that the DFM doesn't keep turning on and off. I never use the cruise control, I just wish there was a 30-mph leeway with the cruise control, ranging from 50 to 80 mph, depending on terrain. I hate braking while going downhill and I hate flooring the gas while going uphill. I'm OK with 50 mph to 80 mph, it doesn't have to be exactly 65 mph. EPA highway gas mileage on mine is 20, I believe, it's a 4x4. I think EPA's testing method includes a full throttle a few times even at highway speeds to stimulate merging into traffic. I don't do that. Some cars are immune to my hypermiling techniques. I could barely hit the 26 mpg my Benz C300's EPA numbers showed, even going 60 mph for a couple hours. It sucked! My Isuzu Trooper said 19, I was lucky to get 13 mpg! No DIC in the Trooper, all hand-checked. My 2012 Ford F-150 responded very well to my hypermiling techniques, usually got 3 to 4 mpg better at 21 mpg, but the 2016 F-150 was pretty much in line with EPA numbers, I was lucky to get 18 mpg in a mix while EPA numbers showed 15/19. Both were Supercrew 4x4 XLT's with 5.0 V8. EPA no longer does the flawed technique which resulted in Prius getting way overly optimistic numbers. I don't know what part was changed though. I have my car in metric so it measures how many litres for every 100 kilometers. When I'm coasting, I do see zero which would be accurate. Zero litres consumed per 100 kilometres. I don't know why it would not show above 99 mpg which is obviously not accurate.

Only 0.25 mpg? Way better than my Ford's trip computer. My 2012 Ford did 850 miles once on a single tank, all highway, and the trip computer reported 27.5 mpg after all kinds of hypermiling techniques. I got excited until I got to the pumps.. it was off by 3 mpg so I actually got 24.5. Still better than EPA's 19 mpg highway. So the 28.8 mpg I got with the Silverado.. it could either be 28.5 or 30.1 mpg (I haven't driven much). That's still damn good! Today, I'll be filling it up with the same gas tank and at the same pump today, will find out how much I'm off. The past three times, I didn't use the same pump.

I'd agree with you if I was still driving the 2012 Ford F-150. Ford's trip computer was every 10,000 miles so I'd reset it every 10k miles. All three times, it was over 23 mpg, usually 23.7 or 23.8, and I can confirm it was overly optimistic by 2 mpg, sometimes 3 mpg. So I got 21 mpg with about 30% city and 70% highway. EPA said it'd get 19 mpg highway so i did better. It is much more spot on with Chevrolet, the past three times I measured it, it was off by 0.2 or 0.3 mpg either way. And others have chimed in, the 2019 and afterwards, the trip computer is much more accurate.

That clearly shows how unreliable EPA numbers are. Sometimes it's spot on, but not always. My Benz barely got EPA's 26 mpg highway while my Silverado easily exceeds it.. 20 mpg highway and I'm getting 26. I'm impressed with the Silverado.

Surprisingly, I spend much less in taxes because my property taxes are fixed at the price I bought my house.. way back in 1995 so I pay literally pennies on the dollar compared to the neighbors. The owners of the brand-new condominiums three miles away face $1,800 a month in taxes and "special assessments" (technically not tax so that's legal). Electric trucks. I don't know if I can live with range anxiety. If I can get at least 800 miles within a single trip and there are filling stations all over, I may reconsider.

Driving for two hours before sunrise, I'd have thought the engine would have warmed up by then. Wouldn't adding tarp on the grill make a difference? I saw trucks doing that in Europe and was told it was for gas mileage. For a while, I thought it was aerodynamic-related and kind of figured it out when summertime arrived. Your 4 mpg difference is probably accurate if you have a Chevy trip computer. After measuring it at the pumps, I found GM's is much more precise, maybe off by 0.2 mpg either way, hot or cold. Ford's was consistently overly optimistic by 1 to 3 mpg, hot or cold. The temperature doesn't fluctuate where I live. In winter, temperature rarely goes below 55°. In summer, it rarely goes above 80°. Heck, even daily temperatures don't fluctuate much. It's been around 65° in the daytime and 56° at nights for the past month. Good to know that cold temperatures negatively impact gas mileage by 4 mpg, I thought it was smaller than that. I am actually very pleased with the 28.8 in my Silverado especially since the same trip would get around 24 on my F-150's overly optimistic trip computer so I might have actually gotten around 21 or 22. A month ago, gas hit $4.39 a gallon, which explains my keen interest. It's nicer having $30 more in my wallet when I arrive in Vegas after a long trip, more money for me to lose in craps.

I only go 80 when it's downhill. I move all the way to the right when going uphill, usually at 45 to 50. When it gets flat, usually 55 to 60, but I'm going to try 51. Easy to do that here, trucks in California aren't allowed to go above 55 so I stay around them and blend in. In cities, I try hard to avoid hitting the brakes. If I see a red light from a distance, I immediately let my foot off the gas and try not to brake until the very last minute. A lot of times, I never need to hit the brake pedal. Then I gently accelerate. I accelerate quicker if somebody is behind me, I'm not a horse's ass. I try to stay on the right or stay in empty lanes. I used to live in Germany, I am very anal about driving etiquette. That's how hard-core I am with hypermiling.

I've consistently gotten above 26 in highway driving. My average after 900 miles is 22 which is about 70 percent city and 30 percent highway. My F-150's sticker said 19 mpg highway and I never reset the trip computer. I got 24 mpg after over 30k miles with about half city and half highway. So, yes, it is representative for me. Sorry if you can't accomplish that.

I have to justify the purchase of the Silverado to my girlfriend, boss, and my parents who lecture me whenever they think a purchase is frivolous. The most common criticism I got for buying a Silverado was the gas mileage so I am now demonstrating to them I am getting the same gas mileage as I did on my 2008 Benz C300, a very tiny cramped sedan with a shitty V-6 and a lousy 228 ponies. Now, I have a big ass V8 with 355 hp, 4x4, and way more space in the back, with the same gas mileage I did on my Benz... so now I can say, "See?"

Ah, thanks for the input! I wanted to find that "sweet spot" but wasn't sure. On my Ford, it was 44 mph. DFM kind of fuzzes it up and I've been having trouble pinpointing it. I am going to try 52 mph, thanks! Many thanks! I also have the 3.23 so that helps

My previous best gas mileage was 28.6 after a drive from Dana Point to Riverside and back. Just now, I did Dana Point to Orange County Airport and back and managed to get 28.8. It's not flat all the way and I went 55 mph to 60 mph. I am very pleased with it. My 2012 F-150 got around 24 but discovered it was overly optimistic when I filled up my tank so I'm guessing around 22 mpg. My understanding is that the Silverado's computer is spot-on so I am getting at least 28 mpg. Not too bad for a 4x4 V8. I am curious to see what I'd get after I fill it up with Mexican gas. I do notice improvement because it doesn't contain ethanol as required in the U.S.

Going 55 on a flat surface, my 5.3 V8 gets me 26 to 27 mpg. Going 65, it drops to around 22 to 23. But I have a 2019. Slowing down makes a big difference, sucks, I know, but that's one way I did it.

I looked it up, I do have the HD. Yes, you're right, Convenience II. I didn't know I had that in mine. I guess that's why I have that issue. I did in the rental car though.. I noticed the quality was quite a bit less than what I was accustomed to.

I have the RST too, and my screen is 8". I think the lower trims have the 7". So my 8" isn't HD? I haven't experienced that. Strangely though, I just rented a Chevrolet Equinox over the weekend and noticed that problem, even said "Service Rear Video System." Seems to be a GM issue.

Just got it yesterday.. and, yep, shifted it in reverse right after starting it. Had to look it up to find out what was causing it. Never had it before and I realized it's because I always back in my garage so I never saw it in the mornings.

Damn good deal.

A lot of F-150 owners had the same problem, it's an easy fix. Seems to happen with all pick-up trucks.

Good reason to get side bars so I could climb in. I just tried it without, forget it. I'm 5' 10" and it is much taller. I'm getting much older too!

Have to agree here. No matter how many gears the transmission has, 4L is way lower than the lowest, no comparison here, probably by a magnitude of ten

No, I don't care about any of this, but 4L is a must since I have been in situations where I needed it. The gearing would not matter, none would have the ultra-low gears the 4L has. I only needed it just once when I was in a situation that required 4L and very convenient. I wanted the Z71 because I thought it had better handling. I later found out that the Z71 has two-speed which is really nice! I would have been pissed if I found out I didn't have it!

I just looked in cars.com for AT4 around here (150 mile radius just so I can get L.A. and San Diego)..it looks like you'd be lucky to get $3k off. Not great deals.

I tried Google... nope. I don't have Wi-Fi and OnStar has been deactivated.. but I had it connected to the Wi-Fi of my house and verified it numerous times but I keep getting this error. Do I really have to buy 4G internet to make this work? I wanted to get the text messaging app.

Mine was $51,060, bought at $41,320, walk out was around $45,000. California caps the documentation fee at $80.. I know it can be $400 in other parts. So I know I won't get screwed in the sales tax or the documentation. I had a great deal and am very happy with mine. That was the reason why I did not do OTD, there really is no reason to if I'm in California. Try e-mailing first, that was what I did with the 2016 Ford. In fact, I went to Ford.com, checked the inventory, picked exactly what I wanted, and picked the cheapest F-150 with what I wanted.. with 302A package, 4x4, and 6.5' bed. The MSRP on that was $51k, I e-mailed the dealership (no number) and they weren't advertising specials. I asked, "$10k off the MSRP like the other dealers and $24k for my 2012 F-150 Supercrew?" We haggled a bit.. and I got $23k for my trade-in and $10k off. That was for the truck with exactly what I wanted.

Right, that's why I said my credit union treats any refinance on a new car as a new car finance provided that it was bought new less than 12 months ago. If it was within 2 months, no credit check, they will assume whatever loan was done the first time. If it was more than 12 months OR if it was refinanced again with the same credit union, then it would be a used car loan subject to blue book values.

Not my credit union. They treat any new loans (within 2 months) as a new car loan where no credit check will be performed. If it's more than 2 months but less than 12 months, they may run a credit check. But, as long as it's less than 12 months, it will be given the new car finance rate. No cashing out.
