Just did some online searching, you should try it some time, and figured out what our difference in MPG is from.
In Candada you use IMPERIAL gallons which are ~1.2 of our gallons.
Went to Toyota Canada website and looked at specs.
Your tank is 17.6 while ours are 21. Same tank just different units of measurement.
I asked you for specifics many messages ago if you read it and replyed in a less smarta s s response than read my message and had answered my questions it could have saved a lot of banter between us.
Now, a friend of mine has your same truck and the best he has gotten was 21mpg american driving 65-70mph on a long trip. That would translate to roughly 25-26 mpg Imperial? Correct me if I'm wrong.
Good luck seeing 28 though.
