Your torque converter may be having issues, decreasing your mileage. Check your transmission fluid and do a tune up.

 

thank you for the suggestions guys and it just past 115k saturday ill change my tranny fluid and seafoam and go from

 

I was going to school in the US for a while and filling up at the border, since I finished school and started filling up in Canada again I've lost close to 100 Km/60 Miles per tank...

I've tried different gas stations thinking maybe that was it but still not as great of mileage





So minus 100 km/ 60 miles off of those pics

 

its possible the gas you were getting in the us didnt have/had less ethanol than the gas your getting in canada

 

Thats my thought, maybe the gas in canada differs from our gas? And i have to think, with your speedo in MPH mode, that essentially means it'll go up to 220mph?

 

Lola did 35 for me on the highway into the berkshires this year with the heat on cruising at 70 and i have no cruise control

 

HAHA! good question maybe I'll try it some time on the track I also wish I could change the Celsius to Fahrenheit when I'm set to KM

 

On winter blend fuel I was getting like 21mpg average in my monte with 166k miles on it (engine rebuilt at 148k)

It appears theyve switched to summer blend now, I'm getting 26mpg average (these #s are combined city/hwy driving).

I lose my torque converter lockup, too, almost constantly once i reach 68-70mph or higher, and normally I try to tun about 73 on the highway.
