I am averaging about 18.9 MPG on 89. I did not buy this truck with gas mileage in mind. However I have averaged much better gas mileage in my Ranger than any other truck I have owned.

i have an STX Supercab and often get 27 mpg or more. warmer weather helps and the a/c on these things doesn't seem to impact mileage. if i travel country roads between 50 and 60 mph i'll get over 28 mpg. the fuel computer always seems to indicate slightly better than i actually get but my numbers are real pencil and paper calculations.Took a trip from NJ to NC this past weekend. I averaged a little over 25 mpg and most of my driving was at 70 mph using the adaptive cruise control.
Does Virginia use winter fuel?
I have never seen 25 mpg in my truck before. I currently have around 23,000 miles on it.
Manual specifically says not to.I wouldn't use MMT based octane booster on anything with cats, or any engine that you don't plan on regularly changing plugs on.
The manual calls for 91 or higher octane for best overall vehicle and engine performance.hot nd high should help mileage on a turbocharged engine but i don't know about 6k - 7k elevation.
to those guys running anything other than 87 octane: have you tried 87 and had problems? modern auto engine technology/electronics should eliminate the need for anything other than what the owner's manual calls for.
i do accelerate gently but i drive the speed limit or sometimes more and at 800 ft. i'm getting about 27mpg (pen and paper calculations, not the ford computer which seems to read up to 1 mpg more). i loaded the truck to max gross twice and went 160 miles from sea level to 800' and still got 25 mpg at 65 mph.
real in-town stop and go driving will kill the mileage. although the new ranger has the engine-off golf cart feature it is not as aggressive as it could be.mine isnt broke in yet, has 1000 miles on it, in town driving mostly right now, after i fill up and do the math etc... last 3 tanks are solid 19.5, truck says 20.5 , so it is off..... i dont drive fast or hard ever... just saying
I will tell you that when I switch to 91 or higher, the truck runs so much better. Peppier, smoother and better MPGs. When I put in sport mode - WOW!That owner's manual clearly says minimum 87 octane is required. ford telling you what you could use a few lines later is like saying they require 5w30 sn+ but they recommend ford oil part #blah blah.
that said, i'm always willing to learn so could you tell me if there was a measurable performance and mph difference between using 87 and 91?
