Most of them do, but they rely on oil change monitors and app notifications for when to perform service. Increasingly, automakers are adding virtual dipsticks, or replacing physical dipsticks with virtual dipsticks, which has its benefits too. Oil color is no long a great indicator of oil health anyway. We live in this funny timeline where we insist on using fire to power our vehicles, so we still have to regularly change the oil in the fire machine.

I definitely can absorb that, and I didn't say you were on welfare or knew anyone on welfare, but thanks for the information? My current fleet is 6 vehicles. The oldest is a 2000, and the 2nd oldest is from 2022, two are diesel, 3 are gas, one is a battery-electric. but I've had all kinds of vehicles, and much, much older, and much higher mileage. I've just never found it interesting that vehicles go 100k, 200k with regular maintenance. But, the boss says I need to get off the computer and back to making McMuffins. The drive-thru is stacking up.

I'd rather work than be on welfare. Inhibited growth is driving an old minivan and thinking anyone cares that it has high mileage. Guess what? Nobody cares.

Are we still talking about the 2.4L in GM's little blobs, and a 10 year old Honda Minivan? Really?

I've definitely had tanks of fuel where the pump clicked off and I just shook my head when I looked at the meter. No freaking way that much gas could even fit in there given what was left, or the known capacity of the tank. But, never pursued it...just added those stations to the list of them that I'll never visit again. I see our state inspection stickers and it's a sign that the pump was possibly accurate at the point and time when the sticker was affixed to the outside of the pump. And that's about all it could mean!

The crap we put up with from the petro-chemical industry... No such thing as Top Tier electrons for EV's or snake-oil additives to clean your EV injectors.

The signage does seem inconsistent. And, at some stations, you'll see a "Top Tier" decal on a pump and second guess if it's actually Top Tier. While I don't doubt that Top Tier fuel is actually a better product, the marketing side seems to be run fast/loose.

That's just sad/unforunate. It would be more funny if the tractor was a John Deere. I'll see myself out.

Diesel $4.99. The other cars take premium, 92. That's $4.87 at the same discount station (lowest price) nearby. ConocoPhilips announced it's laying off 20-25% of its workforce today in a "restructuring". I thought the oil/gas industry was supposed to be on fire. Wait, not like this! lol

I'm not sure how accurate it is, either. But, it is the official site put out there by the organization that heads up Top Tier.

Three of them. According to the official Top Tier website, none of the Costcos in our area sell Top Tier diesel. They sell Top Tier gasoline only. Two Costcos farther out (25+ miles away, in directions I don't regularly travel) sell Top Tier diesel but that's it. None of the local Chevrons, Shells, 76's, Cenex, Sinclair, Texaco, or store brand (Safeway, Fred Meyer) stations sell top tier diesel either. In case anyone wanted to see if their local stations sell Top Tier gas/diesel: https://www.toptiergas.com/fuel-stations/

Top Tier Diesel? GM recommends the use of Top Tier diesel in its diesel engines. If that's not available (which, it's not, around here) they recommend AcDelco branded fuel conditioner to be added to each tank. That stuff is unobtanium, so I'm not really sure what the risk is by running regular diesel from a busy fill station. For other diesels I've owned, I haven't paid any attention to additives or making sure I find top tier diesel. I buy fuel. The truck uses it. And I change fuel filters a little ahead of schedule, just to be extra safe. And that's it. Never had one that's been hard to start, not even in cold.

Fixed that for ya @diyer2....

And she appears to make a lot of money doing it, as most people at her income level do. They typically recognize global supply chain dependencies. Barra adds more value with the automotive company she leads than most of her internet critics.

Manufacturing defect

Loaded question. You'll soon get all kinds of responses about how emissions have ruined modern diesels and it's all a problematic, unreliable nightmare AND its a government conspiracy designed to cost the consumer money. All while George Soros rides around in a jet and a farmer with a diesel tractor is put out of business because of DEF issues. Most of the evidence is anecdotal and spiteful. My anecdotal evidence, having owned a few different modern diesels, is I've never had an issue. Whether by luck or just good maintenance, I've not had problems with SCR systems, EGR's or anything else. But I also don't modify my diesels or do things which cause issues like letting DEF go bad over seasons of no engine use, or using various fuel additives when the manufacturers say specifically don't do that. The reality few people talk about is the trucking industry and the billions of miles driven with SCR systems operational. For the most part people don't have problems, but it's certain you will hear about it when someone does. That provides a skew in both anecdotal evidence, and on forums, etc.

Fewer parts? The 3.0 has 2 fewer cylinders, one less head, 8 fewer spark plugs, only one exhaust manifold instead of two, and doesn't have DFM garbage The LZ0 Duramax has a fully forged crank, steel pistons. It's built very well, but it's also subjected to higher pressures than a 5.3. All the makings of a long lasting small diesel are there...but time will tell.

Which one? LOL Poop rolls downhill? What goes up, can definitely come crashing down? The wheels fall off the clown car eventually? Pedophiles will burn in hell?

I doubt we'll be seeing deleted diesels and carbureted V8's in new vehicles from the factory. This whole undoing is a scam...our nation has grown and has experienced unprecedented wealth accumulation since the Endangerment Finding, so I'm not really sure why we can't make money AND protect our air and water. At any rate, this is another disruption for businesses and investors as it just creates more near term uncertainty, and a higher likelihood that things will snap hard in the other direction again soon.

Before I install this thing, a few more questions: Does the 10L80 require a minimum transmission temperature to achieve TC lockup? I remember this from my 2015 6-speed. Would installing a PPE TB prolong the fluid warmup, and extend the time it takes for TC lockup to occur? Does the 10L80 (specifically, for LZ0 diesels) have an ATF heater? If so, does installing the PPE TB cause any heater to continually heat the fluid in attempt to achieve stock run temperatures of ~195F+ ?

Oh please, god, can it be?

See? I appreciate that. Thank you. Compatible, but probably just different enough to trip my OCD. So I will wait for the $14 quart...grumble grumble...of Dexron ULV to arrive before installing the PPE thermal bypass. Truck is brand new <500 miles so I don't want to be mixing fluids just yet. Else I could have picked up a quart of Valvoline ULV at the store yesterday.

Anyone know of any key differences between the two fluids? Valvoline appears to be commonly available at retail auto parts stores. Dexron is purchased at a dealer or ordered online, at least around here. What do you use when you perform maintenance on your transmission requiring ULV? Safe to mix the two? Are they the same? Different?
