Achieved 17.4 MPH today on 2.5 hour trip through mountains

Who cares about the gas mileage

Seems to me that a lot of people care. Notice the 4 page thread on an anecdotal MPG report from some random highway trip.

The 23-25 highway claim seems significantly exaggerated, but a very uncalibrated computer reading could show it I guess. I don’t question the 17.5 mixed depending on the weight of one’s foot. I’m new to Raptor ownership, but in a year of reading on here prior to purchase I’ve never seen a claim that high.

I’ve had people on forums and in person blowing smoke about very high mileage for a couple of decades now. I recently had someone I work with claiming that his Silverado 1500 V6 was getting 34 miles per gallon on a routine trip from Phoenix to Snowflake (in the mountains), there is no way. I had a 2001 F-150 regular cab short bed 4x2 V6 with a manual that, after tuning, hand calced 23 mpg on multiple trips from Tucson to San Diego. It got over 24 on one of those trips, but I had data to back it up.

I’m hoping I can average at least 16 mpg overall with my driving being 70% highway. I will have the data on Fuelly for anyone to see. I haven’t filled up since the trip back after buying the truck, so I don’t have a hand calced number yet.

Just for kicks, I was on a long very slightly downslope road where I could maintain a bit lower speed for 60-70 miles to just to see what mileage I could get. Was hard to go so slow but kept it at or slightly below 60 (creepin along by Montana standards) on very gradual decline in elevation and got 22.1 MPG. 91 Octane. Almost no slow downs or speed ups the whole time. Really babied it! Yeah, agree 23-25 is grossly exaggerated unless the physical universe in which you live is a downward slope at all times...haha
