I don't think you're making up a story about driving a new Super Duty. I'm glad you think it's fast and fun. That's not the kind of vehicle I'd call fast and fun, but I do think they are nice trucks built for a specific purpose. Excessive oil consumption is a problem. What is excessive? Manufacturers try to define it, although they err on their side to limit warranty and manufacturing costs. Diesel engines burn oil. Gas engines burn oil. By design. And they burn more oil the harder they're worked How much? Over 5k-15k in a light duty pickup you might not notice the cup of oil the engine burns normally, or a couple of cups in a sump that holds a few gallons. On a semi, if you're adding a couple of quarts over 20k that's nothing on a sump that holds 15 gallons. A whole quart in 3k on a 6.6L gas engine? Yeah, I'd consider that excessive if it were my truck. It has a relatively small sump (8 qt?) and 3k miles isn't very far.

I'm curious for the 1500 diesels with exhaust brakes too but haven't towed with mine enough to check it out or care too much. Our motorhome illuminates the brake lights on any engine brake setting (turbo or the actual Jake). Makes us look like idiot drivers riding the brakes all the way down a mountain pass when the opposite is true, we try to use lower speeds and gearing to never need the brakes coming down. We've done the Ike/ I70 too. Supposedly it's a setting that can be updated by Freighliner but IMO not worth paying to bring it to a dealer. I see semi's with this "feature" enabled sometimes too.

Intellectual elitism really needs to make a comeback. You've got retired chemical engineers oil from the oil industry here, an active GM tech who works on these things all day long, and other people telling you you're wrong. You came here asking for opinions. But sure, trust your feelings on this one and keep pumping whatever Ford you owned in the past, that's helping establish your credibility on the issue.

If you knew anything you'd know heavy towing increases oil consumption, pickup, semi, whatever you're driving. 24k still isn't heavy for a lot of 1-tons. Go ahead, call GM and tell their engineers how wrong they are because you once towed 24k.

kNut, that's not heavy. Crossing a scale at 105,500 on the nose is heavy, and legal, here. Pulling off a jobsite at 160k is heavy. Heavy haul is heavy. Pulling that stuff up an 8% grade is heavy. You and your purse crossing a scale at 24k isn't heavy.

Eating cheeseburgers idling a truck isn't exactly creating the cylinder pressures or temperatures that cause oil consumption. 24k, wow, were you pulling your purse?

Try to keep up. Oil consumption is affected by driving habits. That's generally true. I'm not sure anyone has said that is the cause of your L8T's oil consumption, but as a general rule, the harder you work an engine, the more engine it's likely to consume. A quart every 3k does seem like a lot, but, by GM's documentation it's somewhere within their self-determined limits of consumption. The limits are set mostly so they don't have to do anything about it except for extreme cases. If GM won't help you and you're uncomfortable with your L8T consuming a quart every 3k, get rid of the truck? Seems like the only option you have left?

Driving habits definitely affect oil consumption. Grumpy knows. Towing with light trucks, heavy trucks, when you're running full boost more often or spinning gas engines at their peak torque for prolonged periods, they consume more oil. Period. Y'all flat-landers need to come out here in the Mountain West and tow for a while.

You want me to take you and your mental breakdown above seriously and that's just not going to happen. You're free to identify as a victim and whine about how the left hurt you, tell someone who cares.

How is it that everyone who doesn't sympathize with your victimhood is somehow a drug user?

Did you fall and hit your head? Are you OK? Are you going to blame taxes and immigrants for that, too?

Stan, when are prices going to hit $2.00 in Texas?

Yep. Living in the best places in this country comes at a price, doesn't it?

$5.60 for 87. We ain't Hormuzin' yet...

I wouldn't recommend PDR, and any good PDR guy is going to tell you to find a body shop. Paint is missing, and the bedside now has fitment issues as evidenced by the narrowing gap with the tailgate, and the bumper appears to either be bent or it's possible the brackets are bent. Even if you planned to use touch-up paint where the bumper met the bedside and where the tailgate is rubbing, the underlying damage needs to be addressed. A body shop will need to pull out the bedside and possibly replace the bumper depending on where the damage is, disassemble all the adjacent trim and repair the ding and rub with the tailgate, clear and likely clear both the bedside and tailgate. If I had to guess you're looking at a couple thousand dollars in damage to make it look like factory again.

I wonder why the initial secrecy around his death. They knew he was being treated for pneumonia in the days leading up before he died. Of course if it started with something like Covid, his fans would have spiraled out of control on the news.

That's a new one for me...did not know the ambient light sensor also provides input to HVAC. Makes sense though, lots of light probably corresponds with a lot more UV / heat generation inside the cab, so it would increase cooling.

No, there's real truth to this. Disrupt global supply and damage the facilities that produce it, and inventory will be affected. Pretty simple. Pricing is already affected. I never understood the TP freaks during covid. How much toilet paper do you use, jesus. Never heard of a bidet? Sadly there really isn't a substitute for high quality base stock oils.

That's very sad news. But also, his last name is - Busch. Thread title needs to be updated.

Or on modern systems, manual or auto HVAC systems can call for the AC compressor to run in any vent mode or blend door setting based on ambient humidity. Even with the AC button on the controls off/disabled. It's kind of annoying. I find that I can get along with auto HVAC systems, mostly. But really I'd prefer simpler and manually adjustable fan speed/temp/vent setting knobs. We're talking about the inside of a car, not a multi-story building with many rooms.

I don't think the OP's question was ever answered. Sometimes the HVAC doesn't run full-blast to bring the temp down to the set temperature. He gave the example of a 90-degree day (inside of the car is probably ~120+) and the system being set to 71 degrees and not activating fully when he restarts the truck. I would have suspected the Auto Fan setting too, but the problem sounds intermittent, and it sounds like it does run on high as part of the auto setting.

As for sniffing the dipstick, well, I'm not here to kink-shame. For real, though, they wouldn't have a good indicator of exactly how much fuel dilution is occuring by sniffing the dipstick of a GDI engine. They all smell like gas. It's when you suddenly have a half more quart of "oil" according to the dipstick and you know you definitely didn't add any, now that's a problem.

Leaky injectors and HPFP's just aren't that common but it can happen. Most "average owners" follow oil change intervals set by the manufacturer and don't give any of it second thought. And they generally get the service life most of them expect from their car, given that average length of new car ownership is between 7-10 years. The average age of cars on US roads has now risen to almost 13 years old driven by rising prices for new vehicles. My first GDI was in a 2007 GTI here in the US. The engine had been out for 4 years previously in Europe and it first debuted in the US market in 2005. VW has been using the same engine with a few updates since then. Although I sold my GTI I know who still owns it and it's on the original engine and turbo at 156k miles. Pretty good for a small car that has been driven spiritedly its whole life. My second GDI was in a 2014 Camaro, 3.6. No issues for me, and it's still on the road with 120k+ as I know the owner of that car also. Neither of those are rare cars and the engines are used almost ubiquitously across models and plaforms, and those are just two common GDI engines. My third GDI was a 2.0 in a Jeep Wrangler. The engine/trans was fine but the rest of the rig was a Stellantis heap of crap, although I still keep up with that forum and 2.0's (first introduced in 2018) are going strong with 100k. Leaking injectors and HPFP failures aren't common on the 2.0, nor is extreme fuel dilution, coked valves, etc. My fourth GDI engine is a 6.2L LT1. I just don't have many miles on it to give any sort of report yet. Shoot...I forgot I've owned two different 5.3's, a 2014 and a 2020. The 2014 I tracked down since selling it and has almost 200k now, although I don't know the service history. I didn't own the 2020 long enough to care. I'll remember this thread and come back to say "you're right!" if I have problems with my GDI 6.2. It might be 20 years before it hits 100k though.

Sigh. GDI is ~30 year old technology now (since mass production adoption, but the tech has been around a lot longer) and GDI engines have no problem achieving high mileage.

How do you reconcile in their own words (The White House and cabinet members) they "completely destroyed" Iran's nuclear capability last summer in 2025? Were you lied to? They didn't just rebuild Fordow and enrich that much uranium in less than a year. You balked at them being able to do it in 6 years in a post above. We still don't have that supposed stockpile of uranium, but they have destroyed 42 US aircraft since we started this war of choice.
