At the end of the day, A, B or C you'll be fine. A (the one that replaced the R filters) will work on non R (B) applications. You just don't want to use a non R (B) on an R (A) application. So like the 3.6 V6 LGX in the Acadia, XT5, XT6, Blazer and Camaro, or the 3.0TT V6 in the Cadillacs, you do NOT want to use what was the blue PF63 (now PF63B). You have to use the UPF63R black (now PF63A) filter due to the oil pressure those engines create on cold start that can burst a regular PF63. Once the dust settles on the supplier changes hopefully they can clear it all up and simplify things back to how they were.

Fuel mileage? That's all how you use your right foot. Exhaust will give you sound. Stock exhaust 5.3 is 2.75" diameter piping. If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback. I had one on my 2019 old body 5.3 and it was just perfect. Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode. Corsa bumps their catback to 3in diameter.

My info is right from stuff we got from GM for the "A" and "B" and what they replace based on the old Duraguard (blue non "R" filters) and Ultraguard Gold (black "UPFXXR" filters) which are now gone as a result of the First Brands issue.

So far they are all ones "not to stay away from"? I haven't cut any open yet though to compare A and B style. As for what they replace: B = regular "blue" Duraguard A = The "black" Ultraguard Gold. So like UPF63R is now the PF63A. C = That I can tell, alternate supplier or same supplier but alternate model being used. Right now on like PF63 for example though, the "B" is on backorder again so we are using the "A" for both PF63 and UPF63R usage. Same with PF64s, the B is backordered, so we are using A. PF66, the most recent case we got were actually from SAIC-GM from China (GM ETurbo engines so 1.0, 1.2 and 1.3 turbo 3 cylinder). They look like engine assembly plant filters to me which even for US products have different labeling on the cans. These ones are blue with the SAIC-GM logo on them.

Just was clarifying as a lot has happened in the last 12 years in the filter business Definitely wasn't questioning your impression of the new filters as they are definitely of a better construction it seems vs. the blue ones. We did see a couple of the PF48A's and PF64A/B leak though at the seam where the can and the baseplate mate up. Right out of the box too. So I don't know if it was a bad batch that slipped through or what. 48A would be on like 07-14 LS V8 engines, 64A/B would be like 2018-current Chevy Equinox.

Anyone who would be willing to help can't because you left off the last 6 of the VIN. Besides that point. You yourself can answer your own question HERE - GM Recall Information | Chevy account | Chevrolet Put your whole VIN in and it will show you all active and expired warranties and coverages.

Correct. Supplier changes because of the First Brands bankruptcy. From First Brands (Fram) to Premium Guard. Champ Labs hasn't "made" filters for almost 12 years. They got bought by Fram in 2014, and then Fram got bought by First Brands in 2019. First Brands no longer makes oil filters as a result of the bankruptcy. Fram fixed and improved the eCore design that Champ made a long time ago that many people didn't care for. So Champ branded filters for the last 12 years are made by Fram using their old design, and then using the new design that was created under Fram. Premium Guard bought the assets from First Brands mid this year. Oil filters, wipers, air and cabin filters, and respective brand names. Premium Guard makes a lot of private label filters including Napa Gold, Carquest, and others. Their main filter supply flow comes from Vietnam Advanced Filtration Inc. Premium Guard Inc.

Its coolant disguised as oil. TSB 20-NA-166 - 20-NA-166 1..3 "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix" I'd say its the head, and its either leaking at the casting line and dripping down the intake into the cylinder, or its another spot on the casting itself at the cylinder that is getting wet.

Yea that's pretty normal to be off a few degrees after sitting. Usually 2-4 degrees from say a weather app or thermometer. I've seen it a bit more if you are parked facing the sun too when its really hot out.

You SHOULD be. IF you underinflate, you can compromise the truck's handling and stopping. Its an 8400lbs truck. LOTS of weight on the front end empty. Ideally you'll want 55-60psi all the way around. Tire light. GM dealers won't help. LIABILITIES. Others have mentioned tools that exist. That will be your only route.

Open the driver's door jamb. What do the cold tire PSI ratings on the tire placard show? I'm not saying to run it to those numbers, but I would like to know what it says.

Nah. That's called tripping over dollars to pick up pennies. Bean Counters-R-General Motors.

The fact that they went down with the other fob tells me the windows down with remote feature is still on. I would double check those settings in case the other remote decides to start doing it. Should be under "locks and remote start" in the settings page.

See...I think they are worse aside from Habanero. They are all some sort of super dark color like a super dark red or blue or teal. And the new 2027 Silverado EV colors that are coming, same thing. Dark, dark and dark.
