MPG computer any consistency in margin of error?

Recommended Posts

I’ve got a 2016 SEL. Has there been any established data on how wrong the mpg gauge is? Does it vary from car to car or is there a consistent margin of error. On a trip from San Diego to L.A. light early morning traffic with the cruise control on mostly 66-68 miles an hour the mpg read 36.2. Yeah, right!

4cyl or 6? Doing that speed in my ST I have had it as high as 34mpg Imp. I could see it with the 4cyl or with a good tail wind.

I wouldn't say it's impossible then. I find my gauge relatively accurate when I manually calculate it out. Some find it's out a couple mpg too high. At any rate it's very likely you got around that.

First road trip in the 2016 2L ECOboost. Strolling 70-75 mph and was showing 25.6 after 240 miles. Not too stoked about that as the 2018 Odyssey I’m about to sell was getting  28+ mpg on the same route. 
the Edge has just over 30,000 miles on it and had it a week. I’ll prob pour a bottle of Seafoam in it and run a tank of premium through it to see if it improves.
