My lifetime average (26k kms) is 15.8 L / 100km (15.6mpg). Mostly city driving, a lot of short trips, and cold weather from October to April.

It is getting better as the weather warms up, but stop & go traffic really hurts.
Pretty much identical to mine. Although the gas in my oil is lost mpg's.

I was averaging 16-17 completely stock. That is with a commute 75% 60-65 mph and the rest stop and go. There is several miles of steep hills as well in there.

Now on the 295/60R20's it's dropped to around 15. I've notice about a 1 mpg increase since change to summer fuel.

7,000 miles - lifetime average 17.5 - but I won't tow the boat until June. I'm sure that'll kill the average.

1-2 mpg loss is about right with your gear change.

My FX4 max tow "bone stock right now" so far is 16.6 and I only have 14xx miles so far. The first day I bet I idoled it over an hour. It has been getting better, 17.5 on my last tank and only driving around the house. All of my trips have be <20 miles one way. My conclusion also stated above, if you try you can achieve 18 mpg on the EB. I also can see only getting 13 if you really don't care about mpg's. After owning one I can see why people report the mpg's are all over the place. This engine can vary a lot, all about how you drive it.

Bingo. My lifetime is about 17 at 36k miles. Including towing and 4x4 use.
