And for anyone wondering, yes, the Mobil 1 Truck and SUV oil is a GF-6A spec, not the new GF-7.
The "Truck & SUV" label on this always gives me a chuckle. I picture a marketing meeting that went something like: "Guys... I figured out how we make our regular oil sound tougher!" ... "Let's slap Truck & SUV on the bottle!" 😂
Not saying it's bad oil at all. If it meets your vehicle's required specs, it'll do the job. I just don't read "Truck & SUV" and immediately think premium. If that's your thing though, go for it. You'll save $10–$15 and your engine probably isn't going to file a complaint with HR.
For me, the biggest thing is changing your oil on time, every time.
Personally, I still prefer Extended Performance. Not because I'm out here trying to squeeze 20k miles out of an oil change, but because I like the extra cushion. I usually stay under ~10k miles, but I feel better going 10k on an oil rated for 20k.
Also worth mentioning, a lot of vehicles end up with some fuel dilution in the oil between changes. Once fuel starts mixing into the oil, its ability to protect against wear can start taking a noticeable hit. That's one reason stretching intervals too far, even close to 10k is a fairly bad idea, even with extended-life oils.
Project Farm had a pretty good video where he tested motor oils (inside one of them, I know there are a few where he has tested motor oils, it was an earlier one) and showed what fuel contamination can do to an oil's ability to protect. It wasn't pretty.
Knowing this, part of me thinks the better move fir me would be buying the cheaper basic mobile 1 oil like this and changing it every 5k miles. That would probably be even better for my engine than what I currently do woth using Extended Performance for half of its rated life, but I know how lazy I am, and changing it every 5k miles just isn'tgonna happen

I definitely have to walk back my joke about the Truck and SUV label being pure marketing. The additive package is actually distinct from the regular version. It has a 10% boost in anti-wear and anti-sludge additives to handle the high heat and sludge from towing.
Extended Performance gets its high mileage rating differently by upgrading the actual base oil. It uses a heavier blend of true Group IV and Group V synthetic bases engineered to resist breaking down over time, while regular Mobil 1 relies on standard Group III bases.
Although the website is listing the Truck and SUV oil as a GF-6A spec. That comes down to lag of it being updated so they can get rid of stock on the shelf. The newer ILSAC GF-7 and API SQ specs rolled out with a grace period for manufacturers to flush out old retail stock. But, Now that the transition period has wrapped up, Mobil's master data sheets show that the Truck and SUV line, along with Extended Performance, has been fully updated to the new GF-7 standard.
The new spec is a big deal because it forces much stricter testing for timing chain wear and piston deposits as the oil ages.
Your routine completely validates why I am so paranoid about fuel dilution in the first place. I drive a Toyota Hybrid for my daily commute, I don't mind pushing that to 10k with Extended Performance, but my 4x4 GM truck hits that exact wall where the oil clearly smells like fuel contamination around 4,000 miles. . Once fuel thins out the oil, its ability to protect drops off a cliff. Even if an oil has tougher synthetic bases to survive longer, fresh oil will always beat old oil swimming in raw fuel.
Knowing now that Extended Performance does infact have a heavier dosage of anti-wear chemicals and additives vs the others does put me a bit more at ease that ive been spending more money on it each time.
