Hi Folks,
I keep a log of how much gas I use, just about everything since I bought truck new in 04. (I had to do it when I worked as site service engineer and the habit stuck)
Anyway, my quesion is, I was getting around 27~34 mpg averages until Florida went to 10% ethanol fuel.
(34mpg on highway @ 65~75mph) It only dropped to 23mpg when I had 2,000 lbs in back coming from Pennsylvania (brakes were not too happy stopping from 75+)
Now, I have to drive much slower to get even close to the 27mpg.(55~60mph)
I don't know if its the fuel being lower quality/alcohol added or the urban myth? of vehicle ECM/ECU being programmed to use more fuel after 50,000 miles?
My driving style and distance hasn't changed but my speeds have (up to 30mph slower).
The usual suspects have been checked and all service /wear items/tyre pressures set or replaced.
Any thoughts?
