25 000 miles. You don't even have to do the math. Amsoil is a bit more per quart. But it's not 2.5 times more.
Amsoil is blended components yes, but they're all synthetic components.
Again more company line speak! As far as warranty secure, only if changed within manufacture specified intervals not you exaggerated claimed intervals. You are playing a semantics game by calling Amsoil 100% synthetic and saying it's better than a full synthetic oil, all oils are a blend of components. Again with the claim it maintains, I assume you meant viscosity, better. Where's the testing. What makes your detergents much better than other oils. Contaminants in the oil are still Contaminants. Again Where's the testing. You make claims you better be able to back them up.
As tfisher15 has mentioned keep it 70 or under on the highways and keep it under 2K when excelerating. Have you considered a pedal commander/ idrive / sprint booster etc. ? I recently did 1200 mile round trip, with 3 people and roughly 500 pounds of gear. Stock 2wd sport xlt crewcab with muffer delete and a pedal comander. I started with 91-93 octane. On my way out I reset my mpg monitor, put the pedal commander in eco mode and drove the speed limit pretty much everwhere. With slow starts under 2K rpm. When on the interstates ( about 400 miles worth )I kept it at 70 and used the cruise control as much as possible ( cruise cont gets no imput from the pedal commander tho) . When I arrived at my destination I rechecked my mpg and i was pleasantly surprised with 27.8 . On my way back with same people and cargo I ran 87 octane, reset my mpg monitor, disconnected the pedal commander, accelerated and merged with a lead foot and ran 80-85 on the inerstates again with lots of crusise control. Checked my mpg when i pulled into my driveway and it was 19.3. The pedal commander in eco mode certainly helps keep the acceleration slow and smooth, but significantly increases throttle resonse in the upper modes. Very fun in our trucks but certainly not " mission " specific for your purposes ? hope this helps.
Some members have reported mileage gains with the Velossa Tech Big Mouth. There is a whole thread devoted to it if you are interested. For my part, after my mods, including Ford Performance tune, Ford Performance levelling kit, heavier and more aggressive tires, my mileage tanked (sure, pun intended), falling from the low twenties to 18.5. None of this is surprising, and it is hard to know what is the most important factor, not to mention the fact that, with the pandemic and working from home, I do not travel on freeways or highways anymore. Anyway, I did order a Big Mouth, in blue, to match the truck, but have not installed it yet. Hopefully, once the Big Mouth is installed, the pandemic ended, and I am back to freeway flying, I can report some significant gains. Good luck on your mission!
Amsoil = $13.30 a quart Motorcraft synthetic blend is $4.59
I've definitely been interested in that Big Mouth. Let me know if it works for you. Seems too good to be true but for that price it's worth a shot certainly!
Ah, more Amsoil propaganda. Really nice PowerPoint deck put together by Amsoil. Probably the one used in their sales meetings. Still no independent verification.
25,000 mile oil change interval? Say goodbye to you engine warranty. If you think Magnuson Ross protects/allows you to extend manufacture recommended service intervals, you are sadly misinformed. It protects you using aftermarket parts and using non-manufacture service providers. Also, completing maintenance/install yourself as long as it was done according to manufacturers schedule and such part/install/service did not cause the failure.
I always try and keep it under 2000 rpm as best I can. Even when accelerating from a stop. The people around me aren't too happy when it takes me a mile or so to get up to speed, but I don't care. haha Obviously that's not always possible, but it's a good thing to shoot for I think.
