1150 miles and suddenly seeing 5-7 mpg improvement

Mine runs a bit low, the tank actually calculated out to 23.5 mpg.

 

My truck still drives the same as when I drove it off the lot. Maybe my ECU is broken.

 

here are the stats for the Tacoma. 89 octane with ethanol.

 

I average about 18.5- 19.5 mpg

 

I filled up for the 2nd time. Combined hwy/city 17.7, 2nd dbl cab. Seems low.

 

that temperature difference would do it if it wasn't warmed up at the start....mine gets horrible mileage when under 35mpq for a short trip during warm up and then average drops about 1-2 mpg going from 50 to 20 degrees

 

I was having the worst mpg but I just hit 1.1k miles and the transmission doesn't try as hard and I've seen a definite increase of about 3 mpg. We'll see if it continues or if I had a tailwind to and from work today. That's going 70mph, RPM about 1800-1900.

 

You can do 70mph with under 2k rpms....?

 

Yes on both flat, slight up hill and slight downhill.
