For you 5th gen Ram guys with the 5.7 hemi.
I've been experimenting with running 89 octane over the last two months (as recommended) and finally have some results. They were surprising! Below is a good mix of city driving at 35mph avg, interstate at 78mph average, and local hwy at 63mph average.
Data was done by calculations vs. the onboard computer, however the onboard MPGs were spot on in my truck. Truck is a 2019 Limited with the standard 5.7 Hemi, 3.21 gears. I drive average, no hot rodding, but also not grandma like either.
89 octane @ $3.74/g
17mpg
Used 16.17 gallons
Drove 274.89 miles
Cost $59.65
87 octane at $3.34/g
15mpg
To drive 274.89 miles I would’ve used 18.32 gallons
Cost $61.82
Savings per fill up $1.56
Savings per 5k mile oil change $28.37
Boat towing season is just around the corner and I'll be following up with if my long distance towing of 6k lbs improves from 12.5mpg.
