  1. Past hour
  2. Those Western Mountains are a whole 'nuther game compared to Eastern hills. That said, I've noticed a difference even cresting the lowly Catskills in my 442, only 2250ft above sea level. It wasn't the fuel, it was the air. The higher elevation is why less octane is needed than at sea level. Denver for example, a little higher than Gillette, has air that is 82% as dense as at sea level, humidity being equal. This is where forced induction engines shine, because the intake charge is kept at roughly the same air density by the hair dryer. Because the engine is an air pump, the NA engine is only making ~82% of its power as at sea level, all else being equal. Water boils about a degree lower for every 500 ft of elevation increase. The thinner air at elevation has less ability to absorb heat via the radiator; all of these leads to lower available power to climb the grade, along with more heat and less ability to remove it. A decade ago, I towed a 4000 lb U-haul trailer 450 miles with my 110 hp '84 GMC S15 with manual transmission. Even mild grades that an unladen vehicle would never notice had me dropping into 3rd and putting the hazards on at 40 mph in a 65 mph. I've always operated on the principal that a trailer combo should be the slowest vehicle on the road; going slower than traffic, no matter how dense, means one will always have a clear lane ahead of them, important when considering increased stopping distances. Slow down, keep it in 3rd or 4th and watch your RPM and fluid temps, not the speedometer. Do 35 mph going up the grade and turn on your hazards if you need to; I've never understood "needing" to keep up with traffic at the expense of abusing the machinery. I'm sure you'd rather make it home, uneventfully, than blow a coolant hose, head gasket, spin a bearing, wipe the marginal torque converter, etc.
  3. Sunday afternoon consisted of an oil change, tire rotation, and dropped the trans pan to change fluid/filter. Picture is before I spilt the entire clear bin of ATF on my floor.... only to realize I was out of floor dry...
  4. Change the trans fluid and coolant, a 2016 would be due IMO no matter the mileage cheap insurance.
  5. Back in 2015, 2025 was the year the Environmental Protection Agency announced it would begin looking at recalls on its website. This action led to enactment of several new rules designed to make the recall process easier and more transparent. Check it https://iecasimile.com/live-casinos/ and gain information about the live casinos online. In 2022, many of these rules went into effect as new recalls began popping up all over the country verifying consumer concerns about dangerous products.
  6. 2017 1500 SLT, 52kmiles, stock other than GM/Borla. Truck is never used for towing, but is my daily driver. I noticed recently there is an "odd" upshift between 2nd and 3rd at random times. Usually after driving for a while. Took it in to the dealer who says all is good, no burned fluid and can't duplicate the issue--they say they took it up to ~190. I drove the truck about 470 miles this weekend on vacation after dealer cleared it, but monitored the tranny temps more closely and noticed on the long highway drive with minimal cargo/passengers temp is sitting around 225-232. Ambient temps in the upper 90's. This seems high to me with very little load, but I never really paid attention to temps prior to the shifting issue... so no baseline to compare to. What temps are expected/normal?
  7. Today
  8. Hello my silverado lovers. I have a 2019 silverado LT with a 4 inch lift kit. On 22 inch rims and with 33inch tires. I just order my bilstein 5100 for the front and 5160 for the rear. I'm excited... getting them installed friday.
  9. Up top they are clean and snug. I’ll have to dig deeper underneath. If it’s not the connections have any other ideas with a one click at turn over?
  10. Actually, the DEF is more harmful to people then rich diesel trucks. Folks that want to save the environment need to shut down countries like China and India not a few guys that modify their vehicles. The USA has ridiculously strict emission standards compared to most of the world and guess where all of that emissions equipment comes from, CHINA!!! Very sad that we are caught in a myth of saving the planet by choking one sector of the pollution will letting other like airlines off free of ever passing any emissions.
  11. ...probably won't get a response, Platinum LBZ hasn't logged into the site in more than 2 years...
  12. For sale is a lightly used Softopper brand topper for 6.6' beds. This topper only comes out of the garage a couple times a year. No rear window (solid canvas), no boot. I personally like not having the rear window that seems to always crack in cold weather (I have owned 5 of these toppers) and blocks the lights from tailgaters at night. 450.00 I would like to sell local, but shipping and PayPal fees are buyers responsibility. No Friends/Family transactions. PM and email to [email protected] for quick replies.
  13. Banks SKU# 66411 This can be used on a wide variety of gas and diesel trucks ranging from 1999-2016. Please verify if this works for your application. I have used this for the past 6 months and liked it a lot. Mostly used it for fuel economy on long trips empty and tow tune. Never tried the higher tunes. The USB cable went missing, so you will need to grab one of those and for the reason for the lower cost. The reason I am selling is I can now do different modifications since my CP3 conversion and do not have to worry about that issue. 250.00 Buyer pays shipping and PayPal fees (3%). I will not do Friends/Family transactions. Sorry. PM or contact me at [email protected] (or both) for fast responses. Programmer is located in Colorado Springs, CO if you are local.
  14. Tow in 4th for maximum cooling. At the rpms and speeds you mentioned, with stock tires and 3.42 gears, that tells me you were running that mountain in 2nd gear. Quit being a cheap skate and put some high octane gas in that thing when you want to hump over them mountains.
  15. The factory shocks are great if you use the truck as designed.
  16. that depends on what you are using the truck for. go to Rock Auto and browse their selection, you can spend anywhere from about $15 up and the shocks have different performance specs for different uses
  17. Don't confuse sale of assets by ExxonMobil to mean Black Rock bought ExxonMobil. Asset sales happen all the time. El Paso Refining was bought by Chevron USA. Big fish eating little fish and big fish cutting losses from non productive processing units. They have a 'life span' and past that 'Turn Around' cost get silly. SIX new gas stations in my area in since 2020. Three of those large truck stops. Oil isn't going anywhere but that wont stop the rumor mill from boiling over. As of January 1, 2021, there were 129 operable petroleum refineries in the United States. The newest refinery in the United States is the Targa Resources Corporation's 35,000 barrels per calendar day (b/cd) condensate splitter in Channelview, Texas, which began operating in 2019. Condensate splitters are distillation units that process condensate, which is lighter than crude oil. Splitter capacity is included as atmospheric distillation units in U.S. Energy Information Administration (EIA) data. However, the newest refinery with significant downstream unit capacity is Marathon's facility in Garyville, Louisiana. That facility came online in 1977 with an initial atmospheric distillation unit capacity of 200,000 b/cd, and as of January 1, 2021, it had a capacity of 578,000 b/cd. Capacity has also been added to existing refineries through upgrades or new construction. Some recent examples of large increases include In 2012, Motiva upgraded its refinery in Port Arthur, Texas, making it the largest U.S. refinery, with a capacity of 607,000 b/cd as of January 1, 2021. In 2015, Valero expanded its Corpus Christi, Texas refinery after previous expansions, bringing its capacity as of January 1, 2021, to 290,000 b/cd.
  18. What are the best shocks for a 2WD Sierra 1500hd?
  19. i have the same issue on my 3500, i think they get worn from more turns in a direction and out of balance weight loading in the bed
  20. Big oil is now the property of Vanguard Finacial and Black rock financial. my local mobile refinery was purchased by black rock about 8 years ago. so the ball is in thier court if they want to shut us all down in favor of batteries and solar panels
  21. i did a COSTCO run yesterday, and there was nothing but diesel oil on the shelf, The only oil that was NOT available there was the two jugs of Kirkland 10-w30 and 5-w30 for $25. mobile1 oil everywhere at $43 for two jugs.
  22. Those Big Horn Mountains really are something else. So I began the eastward trek today. With full tank of 87 octane, I again started up into these mountains again on 16. The first part was again a serious grade but no signs to say what the percent was. This time I kept it in the 50mph range and never went much over 4k rpms. I didnt try to maintain speed and let it drop when it needed to. Luckily very little traffic and never really held anyone up. By maybe 5 miles up, I got the warning of the air conditioner being shut down because of engine heat and by this time the coolant was at 258⁰. Luckily I was already looking for a pullout and one was right there when this happened. I stopped and let it cool down. From then on, I just kept the AC off and opened the windows instead just to be safe. When I started off again, at times the coolant would get back to the 250⁰ range but then a couple down hill sections helped it cool down again. I was able to make it all the way to Buffalo without having to stop again. It mostly stayed in the 230⁰ range. Interestingly enough one of the longer flat runs, it actually cooled down to just under 180⁰. I thought that was a bit odd. That didn't happen on the way west. Before I hit Buffalo, there was a sign that said there were 5 downhill grades of 8%. After that sign and the first downhill grade, there was another sign with the number of approching grades dropping. But it looks like that initial westward climb was 8%. I tried to calculate how long it was and it looked like maybe 5 miles or just over. So that did put the engine to a real test. Based on what happened heading east, I don't think I can put the blame completely on the 85.5 octane I used the first time through. The first time through, I know I may have been going a little faster and running the rpms a lot higher for as long as I did. I didnt do that this second time. I know the trailer brakes weren't sticking because I have a TPMS system that also shows the temperature of each tire. All maintained roughly the same pressure and temp. And there was no smell or smoke coming from them. Same with truck tire pressure. All were about same and no smell or smoke. Not quite sure what to be looking at but sure seems like something is off.
  23. The guy was doing a public service, the feds are not. Better gas mileage means less fuel used. I'll take that and simplicity over the crap they are forcing upon the public any day.
  24. I had a bit of white vinyl left over from my '21 AT4 so I thought I'd see how the bowties looked in white. This looks better than black IMO. I'm going to have them keep the center caps out of the wheels when I get the tires rotated so I can cover them in white as well.
  25. This discussion got my curiosity up, so I downloaded the OM for the 2022 refreshed Sierra. In the TPMS section: TPMS Sensor Matching Process — Auto Learn Function Each TPMS sensor has a unique identification code. The identification code needs to be matched to a new tire/wheel position after rotating the tires or replacing one or more of the TPMS sensors. When a tire is installed, the vehicle must be stationary for about 20 minutes before the system recalculates. The following relearn process takes up to 10 minutes, driving at a minimum speed of 20 km/h (12 mph). A dash (-) or pressure value will display in the DIC. See Driver Information Center (DIC) (Base Level) Driver Information Center (DIC) (Uplevel) . A warning message displays in the DIC if a problem occurs during the relearn process. Not sure how all this helps the discussion, other than to add the the truck needs to sit before a recalc, and then it needs to be driven up to 10 minutes for the relearn to occur.
