???? Tanks friggin huge. I can’t imagine there’s even a regular passenger vehicle out there w/ a larger one.11.4 is average for mine. Best I have gotten is 13.1. It's a truck I don't worry about my fuel economy, just wish the tank was larger. Sucks having to constantly refuel.
How many miles on it? Took a few thousand for my ‘18 to break in (I suppose) & mileage started noticeably improving.
Also- it’s pretty clear these trucks much prefer 93 octane, Better mpg by .5-1 for me.
I have 12.5k now- no mods other than colder SP542 plugs & moving my license plate to keep IC cooler. That was only recently...I’m averaging 15.5 - that’s for all 12,500 miles
Going over 70-72 on the hwy mileage really seems to drop off, and I can’t help but be 78-80 most of the time.
Well there ya go, check back after 2-3k milesi have like
i have about 500 miles on the truck and i put in 93 octane...
